List tasks running on one or more nodes, defaults to current node
| Name | Type | Default | Description |
|---|---|---|---|
-f, --filter | filter | Filter output based on conditions provided | |
--format | string | Pretty-print tasks using a Go template | |
--no-resolve | bool | Do not map IDs to Names | |
--no-trunc | bool | Do not truncate output | |
-q, --quiet | bool | Only display task IDs |
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.
Note
This is a cluster management command, and must be executed on a swarm manager node. To learn about managers and workers, refer to the Swarm mode section in the documentation.

If there is
more than one filter, then pass multiple flags (e.g., --filter "foo=bar" --filter "bif=baz").
The currently supported filters are:
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.

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

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: busyboxtop.2: busyboxtop.3: busybox
