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

name

The name filter matches on all or part of a node name.

The following filter matches the node with a name equal to swarm-master string.

$ docker node ls -f name=swarm-manager1

ID                           HOSTNAME        STATUS  AVAILABILITY  MANAGER STATUS
e216jshn25ckzbvmwlnh5jr3g *  swarm-manager1  Ready   Active        Leader

id

The id filter matches all or part of a node’s id.

$ docker node ls -f id=1

ID                         HOSTNAME       STATUS  AVAILABILITY  MANAGER STATUS
1bcef6utixb0l0ca7gxuivsj0  swarm-worker2  Ready   Active

label

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

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

$ docker node ls -f "label=foo"

ID                         HOSTNAME       STATUS  AVAILABILITY  MANAGER STATUS
1bcef6utixb0l0ca7gxuivsj0  swarm-worker2  Ready   Active
