  • v1.8.0 Changes

    June 14, 2016

    💥 Breaking Changes

    • 🐳 As announced in 1.7.0, docker-compose rm now removes containers created by docker-compose run by default.

    • 0️⃣ 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.

  • v1.7.1 Changes

    May 04, 2016

    🐛 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.

  • v1.7.0 Changes

    April 13, 2016

    💥 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.

  • v1.6.2 Changes

    February 23, 2016
    • 🐳 Fixed a bug where connecting to a TLS-enabled Docker Engine would fail with a certificate verification error.

  • v1.6.1 Changes

    February 23, 2016

    🐛 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.

  • v1.6.0 Changes

    January 15, 2016

    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).

  • v1.5.2 Changes

    December 03, 2015

    • 🛠 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

  • v1.5.1 Changes

    November 12, 2015

    • 🏗 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.

    • 0️⃣ 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.

  • v1.5.0 Changes

    November 03, 2015

    💥 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:

    🆕 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.
