|
+### New features
|
|
|
+
|
|
|
+#### Compose file version 2.4
|
|
|
+
|
|
|
+- Introduced version 2.4 of the `docker-compose.yml` specification.
|
|
|
+ This version requires Docker Engine 17.12.0 or above.
|
|
|
+
|
|
|
+- Added support for the `platform` parameter in service definitions.
|
|
|
+ If supplied, the parameter is also used when performing build for the
|
|
|
+ service.
|
|
|
+
|
|
|
+#### Compose file version 2.2 and up
|
|
|
+
|
|
|
+- Added support for the `cpu_rt_period` and `cpu_rt_runtime` parameters
|
|
|
+ in service definitions (2.x only).
|
|
|
+
|
|
|
+#### Compose file version 2.1 and up
|
|
|
+
|
|
|
+- Added support for the `cpu_period` parameter in service definitions
|
|
|
+ (2.x only).
|
|
|
+
|
|
|
+- Added support for the `isolation` parameter in service build configurations.
|
|
|
+ Additionally, the `isolation` parameter is used for builds as well if no
|
|
|
+ `build.isolation` parameter is defined. (2.x only)
|
|
|
+
|
|
|
+#### All formats
|
|
|
+
|
|
|
+- Added support for the `--workdir` flag in `docker-compose exec`.
|
|
|
+
|
|
|
+- Added support for the `--compress` flag in `docker-compose build`.
|
|
|
+
|
|
|
+- `docker-compose pull` is now performed in parallel by default. You can
|
|
|
+ opt out using the `--no-parallel` flag. The `--parallel` flag is now
|
|
|
+ deprecated and will be removed in a future version.
|
|
|
+
|
|
|
+- Dashes and underscores in project names are no longer stripped out.
|
|
|
+
|
|
|
+- `docker-compose build` now supports the use of Dockerfile from outside
|
|
|
+ the build context.
|
|
|
+
|
|
|
+### Bugfixes
|
|
|
+
|
|
|
+- Compose now checks that the volume's configuration matches the remote
|
|
|
+ volume, and errors out if a mismatch is detected.
|
|
|
+
|
|
|
+- Fixed a bug that caused Compose to raise unexpected errors when attempting
|
|
|
+ to create several one-off containers in parallel.
|
|
|
+
|
|
|
+- Fixed a bug with argument parsing when using `docker-machine config` to
|
|
|
+ generate TLS flags for `exec` and `run` commands.
|
|
|
+
|
|
|
+- Fixed a bug where variable substitution with an empty default value
|
|
|
+ (e.g. `${VAR:-}`) would print an incorrect warning.
|
|
|
+
|
|
|
+- Improved resilience when encoding of the Compose file doesn't match the
|
|
|
+ system's. Users are encouraged to use UTF-8 when possible.
|
|
|
+
|
|
|
+- Fixed a bug where external overlay networks in Swarm would be incorrectly
|
|
|
+ recognized as inexistent by Compose, interrupting otherwise valid
|
|
|
+ operations.
|
|
|
+
