Change log

1.1.0-rc2 (2015-01-29)

On top of the changelog for 1.1.0-rc1 (see below), the following bugs have been fixed:

  • When an environment variables file specified with env_file doesn't exist, Compose was showing a stack trace instead of a helpful error.

  • Configuration files using the old name (fig.yml) were not being read unless explicitly specified with docker-compose -f. Compose now reads them and prints a deprecation warning.

  • Bash tab completion now reads fig.yml if it's present.

1.1.0-rc1 (2015-01-20)

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 and restart options, analogous to docker run’s --dns-search, --cap-add, --cap-drop and --restart options.

  • Compose now ships with Bash tab completion - see the installation and usage docs at https://github.com/docker/fig/blob/1.1.0-rc1/docs/completion.md

  • A number of bugs have been fixed - see the milestone for details: https://github.com/docker/fig/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. 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 and our IRC channel is now #docker-fig on Freenode.

  • Fig can be used with the official Docker OS X installer. 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!
