Docker Compose 1.22.0 已发布，Docker Compose 是一个可以简化多容器应用组合的编排工具。通过使用 Compose，你可以在一个配置文件中定义应用的组件，包括容器、配置、连接、卷等，然后你可以通过一个简单的命令将所有的东西组合并运行。

Docker Compose 属于一个“应用层”的服务，用户可以定义哪个容器组运行哪个应用，它支持动态改变应用，并在需要时扩展。

该版本主要是修复了 bug，还为 Compose format 增加了新特性。

新特性

Compose format version 3.7

• Introduced version 3.7 of the docker-compose.yml specification.
  This version requires Docker Engine 18.06.0 or above.

• Added support for rollback_config in the deploy configuration

• Added support for the init parameter in service configurations

• Added support for extension fields in service, network, volume, secret,
  and config configurations

Compose format version 2.4

• Added support for extension fields in service, network,
  and volume configurations

Bug 修复

• Fixed a bug that prevented deployment with some Compose files when
  DOCKER_DEFAULT_PLATFORM was set

• Compose will no longer try to create containers or volumes with
  invalid starting characters

• Fixed several bugs that prevented Compose commands from working properly
  with containers created with an older version of Compose

• Fixed an issue with the output of docker-compose config with the
  --compatibility-mode flag enabled when the source file contains
  attachable networks

• Fixed a bug that prevented the gcloud credential store from working
  properly when used with the Compose binary on UNIX

• Fixed a bug that caused connection errors when trying to operate
  over a non-HTTPS TCP connection on Windows

• Fixed a bug that caused builds to fail on Windows if the Dockerfile
  was located in a subdirectory of the build context

• Fixed an issue that prevented proper parsing of UTF-8 BOM encoded
  Compose files on Windows

• Fixed an issue with handling of the double-wildcard (**) pattern in .dockerignore files when using docker-compose build

• Fixed a bug that caused auth values in legacy .dockercfg files to be ignored

• docker-compose build will no longer attempt to create image names starting with an invalid character
