```
### 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](#name)
* [id](#id)
* [label](#label)
* [desired-state](#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.
```bash
$ 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.
```bash
$ 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.
```bash
$ 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:
```bash
$ docker node ps --format "{{.Name}}: {{.Image}}"
top.1: busybox
top.2: busybox
top.3: busybox
```
