node tasks

Usage:  docker node tasks [OPTIONS] NODE

List tasks running on a node

Options:

  -f, --filter value   Filter output based on conditions provided
  --help           Print usage
  -n, --no-resolve     Do not map IDs to Names

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-manager1
ID                         NAME      SERVICE  IMAGE        LAST STATE          DESIRED STATE  NODE
7q92v0nr1hcgts2amcjyqg3pq  redis.1   redis    redis:3.0.6  Running 5 hours     Running        swarm-manager1
b465edgho06e318egmgjbqo4o  redis.6   redis    redis:3.0.6  Running 29 seconds  Running        swarm-manager1
bg8c07zzg87di2mufeq51a2qp  redis.7   redis    redis:3.0.6  Running 5 seconds   Running        swarm-manager1
dkkual96p4bb3s6b10r7coxxt  redis.9   redis    redis:3.0.6  Running 5 seconds   Running        swarm-manager1
0tgctg8h8cech4w0k0gwrmr23  redis.10  redis    redis:3.0.6  Running 5 seconds   Running        swarm-manager1

id

The id filter matches a task's id.

$ docker node tasks -f id=bg8c07zzg87di2mufeq51a2qp swarm-manager1
ID                         NAME      SERVICE  IMAGE        LAST STATE             DESIRED STATE  NODE
bg8c07zzg87di2mufeq51a2qp  redis.7   redis    redis:3.0.6  Running 5 seconds      Running        swarm-manager1

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        LAST STATE          DESIRED STATE  NODE
b465edgho06e318egmgjbqo4o  redis.6  redis    redis:3.0.6  Running 10 minutes  Running        swarm-manager1
bg8c07zzg87di2mufeq51a2qp  redis.7  redis    redis:3.0.6  Running 9 minutes   Running        swarm-manager1
