Filtering (--filter)
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
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 ps -f name=redis swarm-manager1
NAME IMAGE NODE DESIRED STATE CURRENT STATE
redis.1.7q92v0nr1hcgts2amcjyqg3pq redis:3.0.6 swarm-manager1 Running Running 5 hours
redis.6.b465edgho06e318egmgjbqo4o redis:3.0.6 swarm-manager1 Running Running 29 seconds
redis.7.bg8c07zzg87di2mufeq51a2qp redis:3.0.6 swarm-manager1 Running Running 5 seconds
redis.9.dkkual96p4bb3s6b10r7coxxt redis:3.0.6 swarm-manager1 Running Running 5 seconds
redis.10.0tgctg8h8cech4w0k0gwrmr23 redis:3.0.6 swarm-manager1 Running Running 5 seconds
id
The id filter matches a task's id.
$ docker node ps -f id=bg8c07zzg87di2mufeq51a2qp swarm-manager1
NAME IMAGE NODE DESIRED STATE CURRENT STATE
redis.7.bg8c07zzg87di2mufeq51a2qp redis:3.0.6 swarm-manager1 Running Running 5 seconds
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 ps -f "label=usage"
NAME IMAGE NODE DESIRED STATE CURRENT STATE
redis.6.b465edgho06e318egmgjbqo4o redis:3.0.6 swarm-manager1 Running Running 10 minutes
redis.7.bg8c07zzg87di2mufeq51a2qp redis:3.0.6 swarm-manager1 Running Running 9 minutes
desired-state
The desired-state filter can take the values running, shutdown, or accepted.
Format the output (--format)
The formatting options (--format) pretty-prints tasks output
using a Go template.
Valid placeholders for the Go template are listed below:
| Placeholder | Description |
|---|---|
.ID |
Task ID |
.Name |
Task name |
.Image |
Task image |
.Node |
Node ID |
.DesiredState |
Desired state of the task (running, shutdown, or accepted) |
.CurrentState |
Current state of the task |
.Error |
Error |
.Ports |
Task published ports |
When using the --format option, the node ps command will either
output the data exactly as the template declares or, when using the
table directive, includes column headers as well.
The following example uses a template without headers and outputs the
Name and Image entries separated by a colon (:) for all tasks:
$ docker node ps --format "{{.Name}}: {{.Image}}"
top.1: busybox
top.2: busybox
top.3: busybox
