1.2.0 RC1

This is a release candidate for Compose 1.2.0. To try it out, run the following commands:

curl -L https:/docker/compose/releases/download/1.2.0rc1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

Optionally, you can also install command completion for the bash shell.

Here's what's new:

• 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.
• 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.
• Filenames in env_file and volume host paths in 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>.
• Problems with authentication when using images from third-party registries have been fixed.
• 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

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.

To install Compose, run the following commands:

curl -L https:/docker/compose/releases/download/1.1.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

Besides that, there’s a lot of new stuff in this release:

• 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:/docker/compose/blob/1.1.0/docs/completion.md
• We’ve made a few small changes to ensure that Compose will work with Swarm, Docker’s new clustering tool (https:/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. Check the integration doc to see how it's progressing.
• A number of bugs have been fixed - see the milestone for details: https:/docker/compose/issues?q=milestone%3A1.1.0+

1.1.0-rc2

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.
• The PyPi package is now docker-compose.

This is a release candidate for Docker Compose 1.1.0. To try it out, install via curl:

curl -L https:/docker/fig/releases/download/1.1.0-rc2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose; chmod +x /usr/local/bin/docker-compose

(If you install via PyPi, use pip install docker-compose==1.1.0-rc2.)

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.

Here's the changelog for 1.1.0-rc1:

• We’ve made a few small changes to ensure that Compose will work with Swarm, Docker’s new clustering tool (https:/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.

1.0.1

Install/upgrade instructions here.

• 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

Install/upgrade instructions here.

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:/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

Install/upgrade instructions here.

• 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

Install/upgrade instructions here. Note that Fig now requires Docker 1.0 or greater.

• 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

Install/upgrade instructions here. Note that Fig now requires Docker 1.0 or greater.

Lots of new stuff in this one:

• 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
  

• 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 and @mozz100 for their help with this release!

0.4.2

This release fixes various encoding errors when using fig run, fig up and fig build.
