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

When deploying a service, docker resolves the digest for the service's image, and pins the service to that digest. The digest is not shown by default, but is printed if --no-trunc is used;

$ docker service ps --no-trunc redis
NAME                                IMAGE                                                                                NODE      DESIRED STATE  CURRENT STATE

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
name
node
desired-state

ID

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

$ docker service ps -f "id=8" redis
NAME                                IMAGE        NODE      DESIRED STATE  CURRENT STATE
redis.4.8ryt076polmclyihzx67zsssj   redis:3.0.6  worker1   Running        Running 9 seconds
redis.10.8eaxrb2fqpbnv9x30vr06i6vt  redis:3.0.6  manager1  Running        Running 8 seconds

Name

The name filter matches on task names.

$ docker service ps -f "name=redis.1" redis
NAME                                IMAGE        NODE      DESIRED STATE  CURRENT STATE
redis.1.0qihejybwf1x5vqi8lgzlgnpq   redis:3.0.6  manager1  Running        Running 8 seconds

Node

The node filter matches on a node name or a node ID.

$ docker service ps -f "node=manager1" redis
NAME                                IMAGE        NODE      DESIRED STATE  CURRENT STATE
redis.1.0qihejybwf1x5vqi8lgzlgnpq   redis:3.0.6  manager1  Running        Running 8 seconds
redis.5.1x0v8yomsncd6sbvfn0ph6ogc   redis:3.0.6  manager1  Running        Running 8 seconds
redis.9.3w1wu13yuplna8ri3fx47iwad   redis:3.0.6  manager1  Running        Running 8 seconds
redis.10.8eaxrb2fqpbnv9x30vr06i6vt  redis:3.0.6  manager1  Running        Running 8 seconds

desired-state

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