Docker Compose 1.21.0 已发布，获取地址：https://www.docker.com/products/docker

新版本带来了一些新特性，以及 bug 修复：

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.
