1.6.0 RC1

Note that Compose 1.6.0 requires Docker 1.9.0 or later.

If you're a Mac user, the Docker Toolbox will install Compose 1.6.0 for you, alongside the latest versions of the Docker Engine, Machine and Kitematic.

You can use the usual commands to install or upgrade:

curl -L https://github.com/docker/compose/releases/download/1.6.0-rc1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

See the install docs for more install options and instructions.

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.

See the Compose file reference for more information:
https://github.com/docker/compose/blob/1.6.0-rc1/docs/compose-file.md

• 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 want to
keep using links, 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://github.com/docker/compose/blob/1.6.0-rc1/docs/networking.md

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.

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.

1.5.2

Note that Compose 1.5.2 requires Docker 1.7.1 or later.

If you're a Mac user, the Docker Toolbox will install Compose 1.5.2 for you, alongside the latest versions of the Docker Engine, Machine and Kitematic.

You can use the usual commands to install or upgrade:

curl -L https://github.com/docker/compose/releases/download/1.5.2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

See the install docs for more install options and instructions.

Here's what's new:

• 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

Thanks @mnowster, @aanand, @viranch, @StefanScherer, @seguins, @simonvanderveldt, @jonaseck2

1.5.1

Note that Compose 1.5.1 requires Docker 1.7.1 or later.

If you're a Mac user, the Docker Toolbox will install Compose 1.5.1 for you, alongside the latest versions of the Docker Engine, Machine and Kitematic.

You can use the usual commands to install or upgrade:

curl -L https://github.com/docker/compose/releases/download/1.5.1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

See the install docs for more install options and instructions.

Here's what's new:

• 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 printing 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 it's 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

This release contains breaking changes.

Note that Compose 1.5.0 requires Docker 1.7.1 or later.

If you're a Mac or Windows user, the Docker Toolbox will install Compose 1.5.0 for you, alongside the latest versions of the Docker Engine, Machine and Kitematic.

Otherwise, you can use the usual commands to install/upgrade. Either download the binary:

curl -L https://github.com/docker/compose/releases/download/1.5.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

Or pip install -U docker-compose==1.5.0 if you prefer pip.

Here's what's new:

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/129092b7/docs/yml.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/129092b7/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

Firstly, note that Compose 1.4.2 requires Docker 1.7.0 or later.

Secondly, if you're a Mac user, the Docker Toolbox will install Compose 1.4.2 for you, alongside the latest versions of the Docker Engine, Machine and Kitematic.

Otherwise, you can use the usual commands to install/upgrade. Either download the binary:

curl -L https://github.com/docker/compose/releases/download/1.4.2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

Or install the PyPi package:

pip install -U docker-compose==1.4.2

This release fixes a regression in the 1.4.1 release that would cause docker-compose up without the -d option to exit immediately.

1.4.1

Firstly, note that Compose 1.4.1 requires Docker 1.7.0 or later.

Secondly, if you're a Mac user, the Docker Toolbox will install Compose 1.4.1 for you, alongside the latest versions of the Docker Engine, Machine and Kitematic.

Otherwise, you can use the usual commands to install/upgrade. Either download the binary:

curl -L https://github.com/docker/compose/releases/download/1.4.1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

Or install the PyPi package:

pip install -U docker-compose==1.4.1

The following issues were fixed in this release:

• 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

Firstly, note that Compose 1.4.0 requires Docker 1.7.1 or later.

Secondly, if you're a Mac user, the Docker Toolbox will install Compose 1.4.0 for you, alongside the latest versions of the Docker Engine, Machine and Kitematic.

Otherwise, you can use the usual commands to install/upgrade. Either download the binary:

curl -L https://github.com/docker/compose/releases/download/1.4.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

Or install the PyPi package:

pip install -U docker-compose==1.4.0

Here's what's new:

• 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.
