chmod +x /usr/local/bin/docker-compose
See the install docs for more install options and instructions.
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 independs_on
. - Fixed a bug where
networks
andnetwork_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 usingextends
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 acontext
would show a stack trace instead of a helpful validation error message. - Improved compatibility with swarm by only setting a container affinity to the previous instance of a service's container when the service uses an anonymous container volume. Previously the affinity was always set on all containers.
- Fixed the validation of
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.

1.6.0
Note that Compose 1.6.0 requires Docker Engine 1.9.1 or later, or 1.10.0 if you're using version 2 of the Compose File format (see the changelog below).
If you're a Mac or Windows user, the Docker Toolbox will install Compose 1.6.0 for you, alongside the latest versions of Docker Engine, Machine and Kitematic.
Alternatively, you can use the usual commands to install or upgrade:
curl -L https://github.com/docker/compose/releases/download/1.6.0/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.
Check the upgrade guide for full details.
- 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.
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 animage
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, whiledocker-compose pull
will attempt to pull it. - There's a new
events
command for monitoring container events from the application, much likedocker 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 rundocker-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 andextends
. - Added a new command
create
for creating containers without starting them. - Added a new command
down
to stop and remove all the resources created byup
in a single command. - Added support for the
cpu_quota
configuration option. - Added support for the
stop_signal
configuration option. - Commands
start
,restart
,pause
, andunpause
now exit with an error status code if no containers were modified. - Added a new
--abort-on-container-exit
flag toup
which causesup
to stop all container and exit once the first container exits. - Removed support for
FIG_FILE
,FIG_PROJECT_NAME
, and no longer readsfig.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 withextends
. - 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
andlogs
. - 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
ordns_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).
- Fixed a bug where some config options, such as
links
andports
, were not properly merged when using multiple Compose files. - Fixed a bug where setting COMPOSE_PROJECT_NAME to an empty string would result in an empty project name, rather than falling back to the directory name.

1.6.0 RC2
Note that Compose 1.6.0 requires Docker 1.9.1 or later.
If you're a Mac or Windows 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:

chmod +x /usr/local/bin/docker-compose
See the install docs for more install options and instructions.
On top of RC1's considerable list of changes, RC2 contains the following:
links
andexternal_links
are now supported in the version 2 file format.- Added the
depends_on
key for expressing dependencies between services without creating links. - Added the
network_mode
key in the version 2 format as a replacement for version 1'snet
. - Containers now join networks with an additional alias: a short version of the container id.
- Fixed a bug where multiple volumes (both prefixed with the project name and un-prefixed) would be created when a named volume was mounted into a service.
- Configuration under the
networks
key is now properly validated. - Fixed a bug where containers started with
docker-compose run
didn't join networks defined for their service indocker-compose.yml
. - Fixed a
docker-compose scale
bug which would cause all containers to be removed if they exited immediately. - Fixed a bug where
extends
didn't work in the version 2 format. - Fixed "name is reserved" errors when running against Docker 1.10.0 RC1.
- 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).
- Fixed various bugs with zsh completion.

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 usedADD <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

build
- Improved the validation of the
expose
option

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 tobuild
. - 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 usingimage
to usingbuild
. - 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 avolumes_from
was changed. - Fixed a regression in 1.5.0 where non-utf-8 unicode characters would cause
up
orlogs
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
orlogs
, 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 namedmydatavolume
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 theipc
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 likedocker run -p
, for publishing specific ports to the host.docker-compose pause
anddocker-compose unpause
have been implemented, analogous todocker pause
anddocker unpause
.- When using
extends
to copy configuration from another service in the same Compose file, you can omit thefile
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.

, e.g.
volumes_from: ["servicename:ro"]
. - Since Docker now lets you create volumes with names, you can refer to those
volumes by name indocker-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.

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 theipc
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
anddocker-compose unpause
have been implemented,
analogous todocker pause
anddocker unpause
.- When using
extends
to copy configuration from another service in the same
Compose file, you can omit thefile
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.
