docker - docker-compose up vs docker-compose up service1 service2

Question

我在下面有以下 docker-compose 文件。如果我运行docker-compose up一切正常。但是，如果我这样做docker-compose up minio1 minio2 minio3 minio4，则不会创建卷，并且看不到以下日志。它不会创建我假设的卷。我在真正的 docker-compose.yml 文件中有许多其他服务，我不想一直运行docker-compose up和启动每个服务。我如何只启动这 4 个服务并创建卷/网络？

这不会出现在 docker-compose up minio1 minio2 ...

您是否真的检查过是否创建了卷？运行docker-compose up minio1 minio2 minio3 minio4将启动这些容器及其所有依赖项，例如depends_on容器和卷，但只会输出命令中明确列出的容器的日志。

即实际上创建了卷，但这只是没有记录到您，因为您只附加到容器的日志！（并且卷是由docker-compose容器本身而不是由容器本身创建的）。

我在真正的 docker-compose.yml 文件中有许多其他服务，我不想一直运行 docker-compose up 并启动​​每个服务。

从docker-compose1.28.0开始，新的服务配置文件就是为此而生的！您可以将profiles服务标记为仅在特定配置文件中启动：

services:
  minio1:
    profiles: ["minio"]
    #...

  minio2:
    profiles: ["minio"]
    #...

  minio3:
    profiles: ["minio"]
    #...

  minio4:
    profiles: ["minio"]
    #...

  service1:
    profiles: ["other"]
    #...

  service2:
    profiles: ["other"]
    #...

  service3:
    profiles: ["other"]
    #...

  service4:
    profiles: ["other"]
    #...

docker-compose up # start only your default services (without `profiles`)
docker-compose --profile minio up # start default and minio services
docker-compose --profile other up # start default and "other" services

您还可以考虑将服务拆分为多个docker-compose.yml文件：

# only start services in docker-compose.minio.yml
docker-compose -f docker-compose.minio.yml up

# merge docker-compose.minio.yml with docker-compose.yml
# and start all contained services
docker-compose -f docker-compose.yml -f docker-compose.minio.yml up
