Listing the tasks that are part of a service

The following command shows all the tasks that are part of the redis service:

$ docker service ps redis

Filtering

The filtering flag (-f or --filter) format is a key=value pair. If there is more than one filter, then pass multiple flags (e.g. --filter "foo=bar" --filter "bif=baz"). Multiple filter flags are combined as an OR filter. For example, -f name=redis.1 -f name=redis.7 returns both redis.1 and redis.7 tasks.

The currently supported filters are:

ID

The id filter matches on all or a prefix of a task’s ID.

$ docker service ps -f "id=8" redis
ID                         NAME      SERVICE  IMAGE        LAST STATE         DESIRED STATE  NODE
8ryt076polmclyihzx67zsssj  redis.4   redis    redis:3.0.6  Running 4 minutes  Running        worker1
8eaxrb2fqpbnv9x30vr06i6vt  redis.10  redis    redis:3.0.6  Running 4 minutes  Running        manager1

Name

The name filter matches on task names.

$ docker service ps -f "name=redis.1" redis
ID                         NAME      SERVICE  IMAGE        DESIRED STATE  LAST STATE         NODE
0qihejybwf1x5vqi8lgzlgnpq  redis.1   redis    redis:3.0.6  Running        Running 8 seconds  manager1

desired-state

The desired-state filter can take the values running and accepted.
