(Compose files v2.1 and up).
- Fixed a bug where falsy values of `COMPOSE_CONVERT_WINDOWS_PATHS`
(`0`, `false`, empty value) were being interpreted as true.
- Fixed a bug where forward slashes in some .dockerignore patterns weren't
being parsed correctly on Windows
1.9.0 (2016-11-16)
-----------------
**Breaking changes**
- When using Compose with Docker Toolbox/Machine on Windows, volume paths are
no longer converted from `C:\Users` to `/c/Users`-style by default. To
re-enable this conversion so that your volumes keep working, set the
environment variable `COMPOSE_CONVERT_WINDOWS_PATHS=1`. Users of
Docker for Windows are not affected and do not need to set the variable.
New Features
- Interactive mode for `docker-compose run` and `docker-compose exec` is
now supported on Windows platforms. Please note that the `docker` binary
is required to be present on the system for this feature to work.
- Introduced version 2.1 of the `docker-compose.yml` specification. This
version requires to be used with Docker Engine 1.12 or above.
- Added support for setting volume labels and network labels in
`docker-compose.yml`.
- Added support for the `isolation` parameter in service definitions.
- Added support for link-local IPs in the service networks definitions.
- Added support for shell-style inline defaults in variable interpolation.
The supported forms are `${FOO-default}` (fall back if FOO is unset) and
`${FOO:-default}` (fall back if FOO is unset or empty).
- Added support for the `group_add` and `oom_score_adj` parameters in
service definitions.
- Added support for the `internal` and `enable_ipv6` parameters in network
definitions.
- Compose now defaults to using the `npipe` protocol on Windows.
- Overriding a `logging` configuration will now properly merge the `options`
mappings if the `driver` values do not conflict.
Bug Fixes
- Fixed several bugs related to `npipe` protocol support on Windows.
- Fixed an issue with Windows paths being incorrectly converted when
using Docker on Windows Server.
- Fixed a bug where an empty `restart` value would sometimes result in an
exception being raised.
- Fixed an issue where service logs containing unicode characters would
sometimes cause an error to occur.
- Fixed a bug where unicode values in environment variables would sometimes
raise a unicode exception when retrieved.
- Fixed an issue where Compose would incorrectly detect a configuration
mismatch for overlay networks.
1.8.1 (2016-09-22)
-----------------
Bug Fixes
- Fixed a bug where users using a credentials store were not able
to access their private images.
- Fixed a bug where users using identity tokens to authenticate
were not able to access their private images.
- Fixed a bug where an `HttpHeaders` entry in the docker configuration
file would cause Compose to crash when trying to build an image.
- Fixed a few bugs related to the handling of Windows paths in volume
binding declarations.
- Fixed a bug where Compose would sometimes crash while trying to
read a streaming response from the engine.
- Fixed an issue where Compose would crash when encountering an API error
while streaming container logs.
- Fixed an issue where Compose would erroneously try to output logs from
drivers not handled by the Engine's API.
- Fixed a bug where options from the `docker-machine config` command would
not be properly interpreted by Compose.
- Fixed a bug where the connection to the Docker Engine would
sometimes fail when running a large number of services simultaneously.
- Fixed an issue where Compose would sometimes print a misleading
suggestion message when running the `bundle` command.
- Fixed a bug where connection errors would not be handled properly by
Compose during the project initialization phase.
- Fixed a bug where a misleading error would appear when encountering
a connection timeout.
1.8.0 (2016-06-14)
-----------------
**Breaking Changes**
- As announced in 1.7.0, `docker-compose rm` now removes containers
created by `docker-compose run` by default.
- Setting `entrypoint` on a service now empties out any default
command that was set on the image (i.e. any `CMD` instruction in the
Dockerfile used to build it). This makes it consistent with
the `--entrypoint` flag to `docker run`.
New Features
- Added `docker-compose bundle`, a command that builds a bundle file
to be consumed by the new *Docker Stack* commands in Docker 1.12.
- Added `docker-compose push`, a command that pushes service images
to a registry.
- Compose now supports specifying a custom TLS version for
interaction with the Docker Engine using the `COMPOSE_TLS_VERSION`
environment variable.
Bug Fixes
- Fixed a bug where Compose would erroneously try to read `.env`
at the project's root when it is a directory.
- `docker-compose run -e VAR` now passes `VAR` through from the shell
to the container, as with `docker run -e VAR`.
- Improved config merging when multiple compose files are involved
for several service sub-keys.
- Fixed a bug where volume mappings containing Windows drives would
sometimes be parsed incorrectly.
- Fixed a bug in Windows environment where volume mappings of the
host's root directory would be parsed incorrectly.
- Fixed a bug where `docker-compose config` would output an invalid
Compose file if external networks were specified.
- Fixed an issue where unset buildargs would be assigned a string
containing `'None'` instead of the expected empty value.
- Fixed a bug where yes/no prompts on Windows would not show before
receiving input.
- Fixed a bug where trying to `docker-compose exec` on Windows
without the `-d` option would exit with a stacktrace. This will
still fail for the time being, but should do so gracefully.
- Fixed a bug where errors during `docker-compose up` would show
an unrelated stacktrace at the end of the process.
- `docker-compose create` and `docker-compose start` show more
descriptive error messages when something goes wrong.
1.7.1 (2016-05-04)
-----------------
Bug Fixes
- Fixed a bug where the output of `docker-compose config` for v1 files
would be an invalid configuration file.
- Fixed a bug where `docker-compose config` would not check the validity
of links.
- Fixed an issue where `docker-compose help` would not output a list of
available commands and generic options as expected.
- Fixed an issue where filtering by service when using `docker-compose logs`
would not apply for newly created services.
- Fixed a bug where unchanged services would sometimes be recreated in
in the up phase when using Compose with Python 3.
- Fixed an issue where API errors encountered during the up phase would
not be recognized as a failure state by Compose.
- Fixed a bug where Compose would raise a NameError because of an undefined
exception name on non-Windows platforms.
- Fixed a bug where the wrong version of `docker-py` would sometimes be
installed alongside Compose.
- Fixed a bug where the host value output by `docker-machine config default`
would not be recognized as valid options by the `docker-compose`
command line.
- Fixed an issue where Compose would sometimes exit unexpectedly while
reading events broadcasted by a Swarm cluster.
- Corrected a statement in the docs about the location of the `.env` file,
which is indeed read from the current directory, instead of in the same
location as the Compose file.
1.7.0 (2016-04-13)
------------------
**Breaking Changes**
- `docker-compose logs` no longer follows log output by default. It now
matches the behaviour of `docker logs` and exits after the current logs
are printed. Use `-f` to get the old default behaviour.
- Booleans are no longer allows as values for mappings in the Compose file
(for keys `environment`, `labels` and `extra_hosts`). Previously this
was a warning. Boolean values should be quoted so they become string values.
New Features
- Compose now looks for a `.env` file in the directory where it's run and
reads any environment variables defined inside, if they're not already
set in the shell environment. This lets you easily set defaults for
variables used in the Compose file, or for any of the `COMPOSE_*` or
`DOCKER_*` variables.
- Added a `--remove-orphans` flag to both `docker-compose up` and
`docker-compose down` to remove containers for services that were removed
from the Compose file.
- Added a `--all` flag to `docker-compose rm` to include containers created
by `docker-compose run`. This will become the default behavior in the next
version of Compose.
- Added support for all the same TLS configuration flags used by the `docker`
client: `--tls`, `--tlscert`, `--tlskey`, etc.
- Compose files now support the `tmpfs` and `shm_size` options.
- Added the `--workdir` flag to `docker-compose run`
- `docker-compose logs` now shows logs for new containers that are created
after it starts.
- The `COMPOSE_FILE` environment variable can now contain multiple files,
separated by the host system's standard path separator (`:` on Mac/Linux,
`;` on Windows).
- You can now specify a static IP address when connecting a service to a
network with the `ipv4_address` and `ipv6_address` options.
- Added `--follow`, `--timestamp`, and `--tail` flags to the
`docker-compose logs` command.
- `docker-compose up`, and `docker-compose start` will now start containers
in parallel where possible.
- `docker-compose stop` now stops containers in reverse dependency order
instead of all at once.
- Added the `--build` flag to `docker-compose up` to force it to build a new
image. It now shows a warning if an image is automatically built when the
flag is not used.
- Added the `docker-compose exec` command for executing a process in a running
container.
Bug Fixes
- `docker-compose down` now removes containers created by
`docker-compose run`.
- A more appropriate error is shown when a timeout is hit during `up` when
using a tty.
- Fixed a bug in `docker-compose down` where it would abort if some resources
had already been removed.
- Fixed a bug where changes to network aliases would not trigger a service
to be recreated.
- Fix a bug where a log message was printed about creating a new volume
when it already existed.
- Fixed a bug where interrupting `up` would not always shut down containers.
- Fixed a bug where `log_opt` and `log_driver` were not properly carried over
when extending services in the v1 Compose file format.
- Fixed a bug where empty values for build args would cause file validation
to fail.
1.6.2 (2016-02-23)
------------------
- Fixed a bug where connecting to a TLS-enabled Docker Engine would fail with
a certificate verification error.
1.6.1 (2016-02-23)
------------------
Bug Fixes
- Fixed a bug where recreating a container multiple times would cause the
new container to be started without the previous volumes.
- Fixed a bug where Compose would set the value of unset environment variables
to an empty string, instead of a key without a value.
- Provide a better error message when Compose requires a more recent version
of the Docker API.
- Add a missing config field `network.aliases` which allows setting a network
scoped alias for a service.
- Fixed a bug where `run` would not start services listed in `depends_on`.
- Fixed a bug where `networks` and `network_mode` where not merged when using
extends or multiple Compose files.
- Fixed a bug with service aliases where the short container id alias was
only contained 10 characters, instead of the 12 characters used in previous
versions.
- Added a missing log message when creating a new named volume.
- Fixed a bug where `build.args` was not merged when using `extends` or
multiple Compose files.
- Fixed some bugs with config validation when null values or incorrect types
were used instead of a mapping.
- Fixed a bug where a `build` section without a `context` would show a stack
trace instead of a helpful validation message.
- Improved compatibility with swarm by only setting a container affinity to
the previous instance of a services' container when the service uses an
anonymous container volume. Previously the affinity was always set on all
containers.
- Fixed the validation of some `driver_opts` would cause an error if a number
was used instead of a string.
- Some improvements to the `run.sh` script used by the Compose container install
option.
- Fixed a bug with `up --abort-on-container-exit` where Compose would exit,
but would not stop other containers.
- Corrected the warning message that is printed when a boolean value is used
as a value in a mapping.
1.6.0 (2016-01-15)
------------------
Major Features:
- Compose 1.6 introduces a new format for `docker-compose.yml` which lets
you define networks and volumes in the Compose file as well as services. It
also makes a few changes to the structure of some configuration options.
You don't have to use it - your existing Compose files will run on Compose
1.6 exactly as they do today.
Check the upgrade guide for full details:
https://docs.docker.com/compose/compose-file#upgrading
- Support for networking has exited experimental status and is the recommended
way to enable communication between containers.
If you use the new file format, your app will use networking. If you aren't
ready yet, just leave your Compose file as it is and it'll continue to work
just the same.
By default, you don't have to configure any networks. In fact, using
networking with Compose involves even less configuration than using links.
Consult the networking guide for how to use it:
https://docs.docker.com/compose/networking
The experimental flags `--x-networking` and `--x-network-driver`, introduced
in Compose 1.5, have been removed.
- You can now pass arguments to a build if you're using the new file format:
build:
context: .
args:
buildno: 1
- You can now specify both a `build` and an `image` key if you're using the
new file format. `docker-compose build` will build the image and tag it with
the name you've specified, while `docker-compose pull` will attempt to pull
it.
- There's a new `events` command for monitoring container events from
the application, much like `docker events`. This is a good primitive for
building tools on top of Compose for performing actions when particular
things happen, such as containers starting and stopping.
- There's a new `depends_on` option for specifying dependencies between
services. This enforces the order of startup, and ensures that when you run
`docker-compose up SERVICE` on a service with dependencies, those are started
as well.
New Features:
- Added a new command `config` which validates and prints the Compose
configuration after interpolating variables, resolving relative paths, and
merging multiple files and `extends`.
- Added a new command `create` for creating containers without starting them.
- Added a new command `down` to stop and remove all the resources created by
`up` in a single command.
- Added support for the `cpu_quota` configuration option.
- Added support for the `stop_signal` configuration option.
- Commands `start`, `restart`, `pause`, and `unpause` now exit with an
error status code if no containers were modified.
- Added a new `--abort-on-container-exit` flag to `up` which causes `up` to
stop all container and exit once the first container exits.
- Removed support for `FIG_FILE`, `FIG_PROJECT_NAME`, and no longer reads
`fig.yml` as a default Compose file location.
- Removed the `migrate-to-labels` command.
- Removed the `--allow-insecure-ssl` flag.
Bug Fixes:
- Fixed a validation bug that prevented the use of a range of ports in
the `expose` field.
- Fixed a validation bug that prevented the use of arrays in the `entrypoint`
field if they contained duplicate entries.
- Fixed a bug that caused `ulimits` to be ignored when used with `extends`.
- Fixed a bug that prevented ipv6 addresses in `extra_hosts`.
- Fixed a bug that caused `extends` to be ignored when included from
multiple Compose files.
- Fixed an incorrect warning when a container volume was defined in
the Compose file.
- Fixed a bug that prevented the force shutdown behaviour of `up` and
`logs`.
- Fixed a bug that caused `None` to be printed as the network driver name
when the default network driver was used.
- Fixed a bug where using the string form of `dns` or `dns_search` would
cause an error.
- Fixed a bug where a container would be reported as "Up" when it was
in the restarting state.
- Fixed a confusing error message when DOCKER_CERT_PATH was not set properly.
- Fixed a bug where attaching to a container would fail if it was using a
non-standard logging driver (or none at all).
1.5.2 (2015-12-03)
------------------
- Fixed a bug which broke the use of `environment` and `env_file` with
`extends`, and caused environment keys without values to have a `None`
value, instead of a value from the host environment.
- Fixed a regression in 1.5.1 that caused a warning about volumes to be
raised incorrectly when containers were recreated.
- Fixed a bug which prevented building a `Dockerfile` that used `ADD <url>`
- Fixed a bug with `docker-compose restart` which prevented it from
starting stopped containers.
- Fixed handling of SIGTERM and SIGINT to properly stop containers
- Add support for using a url as the value of `build`
- Improved the validation of the `expose` option
1.5.1 (2015-11-12)
------------------
- Add the `--force-rm` option to `build`.
- Add the `ulimit` option for services in the Compose file.
- Fixed a bug where `up` would error with "service needs to be built" if
a service changed from using `image` to using `build`.
- Fixed a bug that would cause incorrect output of parallel operations
on some terminals.
- Fixed a bug that prevented a container from being recreated when the
mode of a `volumes_from` was changed.
- Fixed a regression in 1.5.0 where non-utf-8 unicode characters would cause
`up` or `logs` to crash.
- Fixed a regression in 1.5.0 where Compose would use a success exit status
code when a command fails due to an HTTP timeout communicating with the
docker daemon.
- Fixed a regression in 1.5.0 where `name` was being accepted as a valid
service option which would override the actual name of the service.
- When using `--x-networking` Compose no longer sets the hostname to the
container name.
- When using `--x-networking` Compose will only create the default network
if at least one container is using the network.
- When printings logs during `up` or `logs`, flush the output buffer after
each line to prevent buffering issues from hiding logs.
- Recreate a container if one of its dependencies is being created.
Previously a container was only recreated if it's dependencies already
existed, but were being recreated as well.
- Add a warning when a `volume` in the Compose file is being ignored
and masked by a container volume from a previous container.
- Improve the output of `pull` when run without a tty.
- When using multiple Compose files, validate each before attempting to merge
them together. Previously invalid files would result in not helpful errors.
- Allow dashes in keys in the `environment` service option.
- Improve validation error messages by including the filename as part of the
error message.
1.5.0 (2015-11-03)
------------------
**Breaking changes:**
With the introduction of variable substitution support in the Compose file, any
Compose file that uses an environment variable (`$VAR` or `${VAR}`) in the `command:`
or `entrypoint:` field will break.
Previously these values were interpolated inside the container, with a value
from the container environment. In Compose 1.5.0, the values will be
interpolated on the host, with a value from the host environment.
To migrate a Compose file to 1.5.0, escape the variables with an extra `$`
(ex: `$$VAR` or `$${VAR}`). See
https://github.com/docker/compose/blob/8cc8e61/docs/compose-file.md#variable-substitution
Major features:
- Compose is now available for Windows.
- Environment variables can be used in the Compose file. See
https://github.com/docker/compose/blob/8cc8e61/docs/compose-file.md#variable-substitution
- Multiple compose files can be specified, allowing you to override
settings in the default Compose file. See
https://github.com/docker/compose/blob/8cc8e61/docs/reference/docker-compose.md
for more details.
- Compose now produces better error messages when a file contains
invalid configuration.
- `up` now waits for all services to exit before shutting down,
rather than shutting down as soon as one container exits.
- Experimental support for the new docker networking system can be
enabled with the `--x-networking` flag. Read more here:
https://github.com/docker/docker/blob/8fee1c20/docs/userguide/dockernetworks.md
New features:
- You can now optionally pass a mode to `volumes_from`, e.g.
`volumes_from: ["servicename:ro"]`.
- Since Docker now lets you create volumes with names, you can refer to those
volumes by name in `docker-compose.yml`. For example,
`volumes: ["mydatavolume:/data"]` will mount the volume named
`mydatavolume` at the path `/data` inside the container.
If the first component of an entry in `volumes` starts with a `.`, `/` or
`~`, it is treated as a path and expansion of relative paths is performed as
necessary. Otherwise, it is treated as a volume name and passed straight
through to Docker.
Read more on named volumes and volume drivers here:
https://github.com/docker/docker/blob/244d9c33/docs/userguide/dockervolumes.md
- `docker-compose build --pull` instructs Compose to pull the base image for
each Dockerfile before building.
- `docker-compose pull --ignore-pull-failures` instructs Compose to continue
if it fails to pull a single service's image, rather than aborting.
- You can now specify an IPC namespace in `docker-compose.yml` with the `ipc`
option.
- Containers created by `docker-compose run` can now be named with the
`--name` flag.
- If you install Compose with pip or use it as a library, it now works with
Python 3.
- `image` now supports image digests (in addition to ids and tags), e.g.
`image: "busybox@sha256:38a203e1986cf79639cfb9b2e1d6e773de84002feea2d4eb006b52004ee8502d"`
- `ports` now supports ranges of ports, e.g.
ports:
- "3000-3005"
- "9000-9001:8000-8001"
- `docker-compose run` now supports a `-p|--publish` parameter, much like
`docker run -p`, for publishing specific ports to the host.
- `docker-compose pause` and `docker-compose unpause` have been implemented,
analogous to `docker pause` and `docker unpause`.
- When using `extends` to copy configuration from another service in the same
Compose file, you can omit the `file` option.
- Compose can be installed and run as a Docker image. This is an experimental
feature.
Bug fixes:
- All values for the `log_driver` option which are supported by the Docker
daemon are now supported by Compose.
- `docker-compose build` can now be run successfully against a Swarm cluster.
1.4.2 (2015-09-22)
------------------
- Fixed a regression in the 1.4.1 release that would cause `docker-compose up`
without the `-d` option to exit immediately.
1.4.1 (2015-09-10)
------------------
The following bugs have been fixed:
- Some configuration changes (notably changes to `links`, `volumes_from`, and
`net`) were not properly triggering a container recreate as part of
`docker-compose up`.
- `docker-compose up <service>` was showing logs for all services instead of
just the specified services.
- Containers with custom container names were showing up in logs as
`service_number` instead of their custom container name.
- When scaling a service sometimes containers would be recreated even when
the configuration had not changed.
1.4.0 (2015-08-04)
------------------
- By default, `docker-compose up` now only recreates containers for services whose configuration has changed since they were created. This should result in a dramatic speed-up for many applications.
The experimental `--x-smart-recreate` flag which introduced this feature in Compose 1.3.0 has been removed, and a `--force-recreate` flag has been added for when you want to recreate everything.
- Several of Compose's commands - `scale`, `stop`, `kill` and `rm` - now perform actions on multiple containers in parallel, rather than in sequence, which will run much faster on larger applications.
- You can now specify a custom name for a service's container with `container_name`. Because Docker container names must be unique, this means you can't scale the service beyond one container.
- You no longer have to specify a `file` option when using `extends` - it will default to the current file.
- Service names can now contain dots, dashes and underscores.
- Compose can now read YAML configuration from standard input, rather than from a file, by specifying `-` as the filename. This makes it easier to generate configuration dynamically:
$ echo 'redis: {"image": "redis"}' | docker-compose --file - up
- There's a new `docker-compose version` command which prints extended information about Compose's bundled dependencies.
- `docker-compose.yml` now supports `log_opt` as well as `log_driver`, allowing you to pass extra configuration to a service's logging driver.
- `docker-compose.yml` now supports `memswap_limit`, similar to `docker run --memory-swap`.
- When mounting volumes with the `volumes` option, you can now pass in any mode supported by the daemon, not just `:ro` or `:rw`. For example, SELinux users can pass `:z` or `:Z`.
- You can now specify a custom volume driver with the `volume_driver` option in `docker-compose.yml`, much like `docker run --volume-driver`.
- A bug has been fixed where Compose would fail to pull images from private registries serving plain (unsecured) HTTP. The `--allow-insecure-ssl` flag, which was previously used to work around this issue, has been deprecated and now has no effect.
- A bug has been fixed where `docker-compose build` would fail if the build depended on a private Hub image or an image from a private registry.
- A bug has been fixed where Compose would crash if there were containers which the Docker daemon had not finished removing.
- Two bugs have been fixed where Compose would sometimes fail with a "Duplicate bind mount" error, or fail to attach volumes to a container, if there was a volume path specified in `docker-compose.yml` with a trailing slash.
Thanks @mnowster, @dnephin, @ekristen, @funkyfuture, @jeffk and @lukemarsden!
1.3.3 (2015-07-15)
------------------
Two regressions have been fixed:
- When stopping containers gracefully, Compose was setting the timeout to 0, effectively forcing a SIGKILL every time.
- Compose would sometimes crash depending on the formatting of container data returned from the Docker API.
1.3.2 (2015-07-14)
------------------
The following bugs have been fixed:
- When there were one-off containers created by running `docker-compose run` on an older version of Compose, `docker-compose run` would fail with a name collision. Compose now shows an error if you have leftover containers of this type lying around, and tells you how to remove them.
- Compose was not reading Docker authentication config files created in the new location, `~/docker/config.json`, and authentication against private registries would therefore fail.
- When a container had a pseudo-TTY attached, its output in `docker-compose up` would be truncated.
- `docker-compose up --x-smart-recreate` would sometimes fail when an image tag was updated.
- `docker-compose up` would sometimes create two containers with the same numeric suffix.
- `docker-compose rm` and `docker-compose ps` would sometimes list services that aren't part of the current project (though no containers were erroneously removed).
- Some `docker-compose` commands would not show an error if invalid service names were passed in.
Thanks @dano, @josephpage, @kevinsimper, @lieryan, @phemmer, @soulrebel and @sschepens!
1.3.1 (2015-06-21)
------------------
The following bugs have been fixed:
- `docker-compose build` would always attempt to pull the base image before building.
- `docker-compose help migrate-to-labels` failed with an error.
- If no network mode was specified, Compose would set it to "bridge", rather than allowing the Docker daemon to use its configured default network mode.
1.3.0 (2015-06-18)
------------------
Firstly, two important notes:
- **This release contains breaking changes, and you will need to either remove or migrate your existing containers before running your app** - see the [upgrading section of the install docs](https://github.com/docker/compose/blob/1.3.0rc1/docs/install.md#upgrading) for details.
- Compose now requires Docker 1.6.0 or later.
We've done a lot of work in this release to remove hacks and make Compose more stable:
- Compose now uses container labels, rather than names, to keep track of containers. This makes Compose both faster and easier to integrate with your own tools.
- Compose no longer uses "intermediate containers" when recreating containers for a service. This makes `docker-compose up` less complex and more resilient to failure.
There are some new features:
- `docker-compose up` has an **experimental** new behaviour: it will only recreate containers for services whose configuration has changed in `docker-compose.yml`. This will eventually become the default, but for now you can take it for a spin:
$ docker-compose up --x-smart-recreate
- When invoked in a subdirectory of a project, `docker-compose` will now climb up through parent directories until it finds a `docker-compose.yml`.
Several new configuration keys have been added to `docker-compose.yml`:
- `dockerfile`, like `docker build --file`, lets you specify an alternate Dockerfile to use with `build`.
- `labels`, like `docker run --labels`, lets you add custom metadata to containers.
- `extra_hosts`, like `docker run --add-host`, lets you add entries to a container's `/etc/hosts` file.
- `pid: host`, like `docker run --pid=host`, lets you reuse the same PID namespace as the host machine.
- `cpuset`, like `docker run --cpuset-cpus`, lets you specify which CPUs to allow execution in.
- `read_only`, like `docker run --read-only`, lets you mount a container's filesystem as read-only.
- `security_opt`, like `docker run --security-opt`, lets you specify [security options](https://docs.docker.com/engine/reference/run/#security-configuration).
- `log_driver`, like `docker run --log-driver`, lets you specify a [log driver](https://docs.docker.com/engine/reference/run/#logging-drivers-log-driver).
Many bugs have been fixed, including the following:
- The output of `docker-compose run` was sometimes truncated, especially when running under Jenkins.
- A service's volumes would sometimes not update after volume configuration was changed in `docker-compose.yml`.
- Authenticating against third-party registries would sometimes fail.
- `docker-compose run --rm` would fail to remove the container if the service had a `restart` policy in place.
- `docker-compose scale` would refuse to scale a service beyond 1 container if it exposed a specific port number on the host.
- Compose would refuse to create multiple volume entries with the same host path.

1.2.0 (2015-04-16)
------------------
- `docker-compose.yml` now supports an `extends` option, which enables a service to inherit configuration from another service in another configuration file. This is really good for sharing common configuration between apps, or for configuring the same app for different environments. Here's the [documentation](https://github.com/docker/compose/blob/master/docs/yml.md#extends).
- When using Compose with a Swarm cluster, containers that depend on one another will be co-scheduled on the same node. This means that most Compose apps will now work out of the box, as long as they don't use `build`.
- Repeated invocations of `docker-compose up` when using Compose with a Swarm cluster now work reliably.
- Directories passed to `build`, filenames passed to `env_file` and volume host paths passed to `volumes` are now treated as relative to the *directory of the configuration file*, not the directory that `docker-compose` is being run in. In the majority of cases, those are the same, but if you use the `-f|--file` argument to specify a configuration file in another directory, **this is a breaking change**.
- A service can now share another service's network namespace with `net: container:<service>`.
- `volumes_from` and `net: container:<service>` entries are taken into account when resolving dependencies, so `docker-compose up <service>` will correctly start all dependencies of `<service>`.
- `docker-compose run` now accepts a `--user` argument to specify a user to run the command as, just like `docker run`.
- The `up`, `stop` and `restart` commands now accept a `--timeout` (or `-t`) argument to specify how long to wait when attempting to gracefully stop containers, just like `docker stop`.
- `docker-compose rm` now accepts `-f` as a shorthand for `--force`, just like `docker rm`.

1.1.0 (2015-02-25)
------------------
Fig has been renamed to Docker Compose, or just Compose for short. This has several implications for you:
- The command you type is now `docker-compose`, not `fig`.
- You should rename your fig.yml to docker-compose.yml.
- If you’re installing via PyPI, the package is now `docker-compose`, so install it with `pip install docker-compose`.
Besides that, there’s a lot of new stuff in this release:
- We’ve made a few small changes to ensure that Compose will work with Swarm, Docker’s new clustering tool (https://github.com/docker/swarm). Eventually you'll be able to point Compose at a Swarm cluster instead of a standalone Docker host and it’ll run your containers on the cluster with no extra work from you. As Swarm is still developing, integration is rough and lots of Compose features don't work yet.
- `docker-compose run` now has a `--service-ports` flag for exposing ports on the given service. This is useful for e.g. running your webapp with an interactive debugger.
- You can now link to containers outside your app with the `external_links` option in docker-compose.yml.
- You can now prevent `docker-compose up` from automatically building images with the `--no-build` option. This will make fewer API calls and run faster.
- If you don’t specify a tag when using the `image` key, Compose will default to the `latest` tag, rather than pulling all tags.
- `docker-compose kill` now supports the `-s` flag, allowing you to specify the exact signal you want to send to a service’s containers.
- docker-compose.yml now has an `env_file` key, analogous to `docker run --env-file`, letting you specify multiple environment variables in a separate file. This is great if you have a lot of them, or if you want to keep sensitive information out of version control.
- docker-compose.yml now supports the `dns_search`, `cap_add`, `cap_drop`, `cpu_shares` and `restart` options, analogous to `docker run`’s `--dns-search`, `--cap-add`, `--cap-drop`, `--cpu-shares` and `--restart` options.
- Compose now ships with Bash tab completion - see the installation and usage docs at https://github.com/docker/compose/blob/1.1.0/docs/completion.md
- A number of bugs have been fixed - see the milestone for details: https://github.com/docker/compose/issues?q=milestone%3A1.1.0+

1.0.1 (2014-11-04)
------------------
- Added an `--allow-insecure-ssl` option to allow `fig up`, `fig run` and `fig pull` to pull from insecure registries.
- Fixed `fig run` not showing output in Jenkins.
- Fixed a bug where Fig couldn't build Dockerfiles with ADD statements pointing at URLs.
1.0.0 (2014-10-16)
------------------
The highlights:
- [Fig has joined Docker.](https://www.orchardup.com/blog/orchard-is-joining-docker) Fig will continue to be maintained, but we'll also be incorporating the best bits of Fig into Docker itself.
This means the GitHub repository has moved to [https://github.com/docker/fig](https://github.com/docker/fig) and our IRC channel is now #docker-fig on Freenode.
- Fig can be used with the [official Docker OS X installer](https://docs.docker.com/installation/mac/). Boot2Docker will mount the home directory from your host machine so volumes work as expected.
- Fig supports Docker 1.3.
- It is now possible to connect to the Docker daemon using TLS by using the `DOCKER_CERT_PATH` and `DOCKER_TLS_VERIFY` environment variables.
- There is a new `fig port` command which outputs the host port binding of a service, in a similar way to `docker port`.
- There is a new `fig pull` command which pulls the latest images for a service.
- There is a new `fig restart` command which restarts a service's containers.
- Fig creates multiple containers in service by appending a number to the service name (e.g. `db_1`, `db_2`, etc). As a convenience, Fig will now give the first container an alias of the service name (e.g. `db`).
This link alias is also a valid hostname and added to `/etc/hosts` so you can connect to linked services using their hostname. For example, instead of resolving the environment variables `DB_PORT_5432_TCP_ADDR` and `DB_PORT_5432_TCP_PORT`, you could just use the hostname `db` and port `5432` directly.
- Volume definitions now support `ro` mode, expanding `~` and expanding environment variables.
- `.dockerignore` is supported when building.
- The project name can be set with the `FIG_PROJECT_NAME` environment variable.
- The `--env` and `--entrypoint` options have been added to `fig run`.
- The Fig binary for Linux is now linked against an older version of glibc so it works on CentOS 6 and Debian Wheezy.
Other things:
- `fig ps` now works on Jenkins and makes fewer API calls to the Docker daemon.
- `--verbose` displays more useful debugging output.
- When starting a service where `volumes_from` points to a service without any containers running, that service will now be started.
- Lots of docs improvements. Notably, environment variables are documented and official repositories are used throughout.
Thanks @dnephin, @d11wtq, @marksteve, @rubbish, @jbalonso, @timfreund, @alunduil, @mieciu, @shuron, @moss, @suzaku and @chmouel! Whew.
0.5.2 (2014-07-28)
------------------
- Added a `--no-cache` option to `fig build`, which bypasses the cache just like `docker build --no-cache`.
- Fixed the `dns:` fig.yml option, which was causing fig to error out.
- Fixed a bug where fig couldn't start under Python 2.6.
- Fixed a log-streaming bug that occasionally caused fig to exit.
Thanks @dnephin and @marksteve!
0.5.1 (2014-07-11)
------------------
- If a service has a command defined, `fig run [service]` with no further arguments will run it.
- The project name now defaults to the directory containing fig.yml, not the current working directory (if they're different)
- `volumes_from` now works properly with containers as well as services
- Fixed a race condition when recreating containers in `fig up`
Thanks @ryanbrainard and @d11wtq!
0.5.0 (2014-07-11)
------------------
- Fig now starts links when you run `fig run` or `fig up`.
For example, if you have a `web` service which depends on a `db` service, `fig run web ...` will start the `db` service.
- Environment variables can now be resolved from the environment that Fig is running in. Just specify it as a blank variable in your `fig.yml` and, if set, it'll be resolved:
```
environment:
RACK_ENV: development
SESSION_SECRET:
```
- `volumes_from` is now supported in `fig.yml`. All of the volumes from the specified services and containers will be mounted:
```
volumes_from:
- service_name
- container_name
```
- A host address can now be specified in `ports`:
```
ports:
- "0.0.0.0:8000:8000"
- "127.0.0.1:8001:8001"
```
- The `net` and `workdir` options are now supported in `fig.yml`.
- The `hostname` option now works in the same way as the Docker CLI, splitting out into a `domainname` option.
- TTY behaviour is far more robust, and resizes are supported correctly.
- Load YAML files safely.
Thanks to @d11wtq, @ryanbrainard, @rail44, @j0hnsmith, @binarin, @Elemecca, @mozz100 and @marksteve for their help with this release!
