利用方法docker compose ps [OPTIONS] [SERVICE...]

内容説明

Lists containers for a Compose project, with current status and exposed ports.

$ docker compose ps
NAME            IMAGE     COMMAND           SERVICE    CREATED         STATUS          PORTS
example-foo-1   alpine    "/entrypoint.…"   foo        4 seconds ago   Up 2 seconds    0.0.0.0:8080->80/tcp

By default, only running containers are shown. --all flag can be used to include stopped containers.

$ docker compose ps --all
NAME            IMAGE     COMMAND           SERVICE    CREATED         STATUS          PORTS
example-foo-1   alpine    "/entrypoint.…"   foo        4 seconds ago   Up 2 seconds    0.0.0.0:8080->80/tcp
example-bar-1   alpine    "/entrypoint.…"   bar        4 seconds ago   exited (0)

利用例

Format the output (--format)

By default, the docker compose ps command uses a table ("pretty") format to show the containers. The --format flag allows you to specify alternative presentations for the output. Currently, supported options are pretty (default), and json, which outputs information about the containers as a JSON array:

$ docker compose ps --format json
[{"ID":"1553b0236cf4d2715845f053a4ee97042c4f9a2ef655731ee34f1f7940eaa41a","Name":"example-bar-1","Command":"/docker-entrypoint.sh nginx -g 'daemon off;'","Project":"example","Service":"bar","State":"exited","Health":"","ExitCode":0,"Publishers":null},{"ID":"f02a4efaabb67416e1ff127d51c4b5578634a0ad5743bd65225ff7d1909a3fa0","Name":"example-foo-1","Command":"/docker-entrypoint.sh nginx -g 'daemon off;'","Project":"example","Service":"foo","State":"running","Health":"","ExitCode":0,"Publishers":[{"URL":"0.0.0.0","TargetPort":80,"PublishedPort":8080,"Protocol":"tcp"}]}]

The JSON output allows you to use the information in other tools for further processing, for example, using the jq utility to pretty-print the JSON:

$ docker compose ps --format json | jq .

        "PublishedPort": 8080,
        "Protocol": "tcp"
      }
    ]
  }
]

Filter containers by status (--status)

Use the --status flag to filter the list of containers by status. For example, to show only containers that are running or only containers that have exited:

$ docker compose ps --status=running
NAME            IMAGE     COMMAND           SERVICE    CREATED         STATUS          PORTS
example-foo-1   alpine    "/entrypoint.…"   foo        4 seconds ago   Up 2 seconds    0.0.0.0:8080->80/tcp

$ docker compose ps --status=exited
NAME            IMAGE     COMMAND           SERVICE    CREATED         STATUS          PORTS
example-bar-1   alpine    "/entrypoint.…"   bar        4 seconds ago   exited (0)

Filter containers by status (--filter)

The --status flag is a convenient shorthand for the --filter status=<status> flag. The example below is the equivalent to the example from the previous section, this time using the --filter flag:

$ docker compose ps --filter status=running
NAME            IMAGE     COMMAND           SERVICE    CREATED         STATUS          PORTS
example-foo-1   alpine    "/entrypoint.…"   foo        4 seconds ago   Up 2 seconds    0.0.0.0:8080->80/tcp

The docker compose ps command currently only supports the --filter status=<status> option, but additional filter options may be added in the future.
