node tasks

Usage:  docker node tasks [OPTIONS] NODE

List tasks running on a node

Options:
  -a, --all            Display all instances
  -f, --filter value   Filter output based on conditions provided
  --help           Print usage
  -n, --no-resolve     Do not map IDs to Names

Lists all the tasks on a Node that Docker knows about. You can filter using the -f or --filter flag. Refer to the filtering section for more information about available filter options.

Example output:

$ docker node tasks swarm-master
ID                         NAME     SERVICE  IMAGE        DESIRED STATE  LAST STATE       NODE

Filtering

The filtering flag (-f or --filter) format is of "key=value". If there is more than one filter, then pass multiple flags (e.g., --filter "foo=bar" --filter "bif=baz")

The currently supported filters are:

  • name
  • id
  • label
  • desired_state

name

The name filter matches on all or part of a task's name.

The following filter matches all tasks with a name containing the redis string.

$ docker node tasks -f name=redis swarm-master
ID                         NAME     SERVICE  IMAGE        DESIRED STATE  LAST STATE       NODE
dx2g0fe3zsdb6y6q453f8dqw2  redis.1  redis    redis:3.0.6  RUNNING        RUNNING 2 hours  swarm-master
f33pcf8lwhs4c1t4kq8szwzta  redis.4  redis    redis:3.0.6  RUNNING        RUNNING 2 hours  swarm-master
5v26yzixl3one3ptjyqqbd0ro  redis.5  redis    redis:3.0.6  RUNNING        RUNNING 2 hours  swarm-master
adcaphlhsfr30d47lby6walg6  redis.8  redis    redis:3.0.6  RUNNING        RUNNING 2 hours  swarm-master
chancjvk9tex6768uzzacslq2  redis.9  redis    redis:3.0.6  RUNNING        RUNNING 2 hours  swarm-master

id

The id filter matches a task's id.

$ docker node tasks -f id=f33pcf8lwhs4c1t4kq8szwzta swarm-master
ID                         NAME     SERVICE  IMAGE        DESIRED STATE  LAST STATE       NODE
f33pcf8lwhs4c1t4kq8szwzta  redis.4  redis    redis:3.0.6  RUNNING        RUNNING 2 hours  swarm-master

label

The label filter matches tasks based on the presence of a label alone or a label and a value.

The following filter matches tasks with the usage label regardless of its value.

$ docker node tasks -f "label=usage"
ID                         NAME     SERVICE  IMAGE        DESIRED STATE  LAST STATE       NODE
dx2g0fe3zsdb6y6q453f8dqw2  redis.1  redis    redis:3.0.6  RUNNING        RUNNING 2 hours  swarm-master
f33pcf8lwhs4c1t4kq8szwzta  redis.4  redis    redis:3.0.6  RUNNING        RUNNING 2 hours  swarm-master
