- [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.
- 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:
