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
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
.
Formatting
The formatting options (--format
) pretty-prints tasks output
using a Go template.
Valid placeholders for the Go template are listed below:
Placeholder | Description |
---|---|
.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
