## Description
Lists the tasks that are running as part of the specified stack.
> **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](https://docs.docker.com/engine/swarm/) in the
> documentation.
## Examples
### List the tasks that are part of a stack
The following command shows all the tasks that are part of the `voting` stack:
```console
$ docker stack ps voting
ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS
xim5bcqtgk1b voting_worker.1 dockersamples/examplevotingapp_worker:latest node2 Running Running 2 minutes ago

kqgdmededccb voting_vote.2 dockersamples/examplevotingapp_vote:before node2 Running Running 2 minutes ago
t72q3z038jeh voting_redis.2 redis:alpine node3 Running Running 3 minutes ago
```
### Filtering
The filtering flag (`-f` or `--filter`) format is a `key=value` pair. If there
is more than one filter, then pass multiple flags (e.g. `--filter "foo=bar" --filter "bif=baz"`).
Multiple filter flags are combined as an `OR` filter. For example,
`-f name=redis.1 -f name=redis.7` returns both `redis.1` and `redis.7` tasks.
The currently supported filters are:
* [id](#id)
* [name](#name)
* [node](#node)
* [desired-state](#desired-state)
#### id
The `id` filter matches on all or a prefix of a task's ID.
```console
$ docker stack ps -f "id=t" voting
ID NAME IMAGE NODE DESIRED STATE CURRENTSTATE ERROR PORTS
tz6j82jnwrx7 voting_db.1 postgres:9.4 node1 Running Running 14 minutes ago
t72q3z038jeh voting_redis.2 redis:alpine node3 Running Running 14 minutes ago
```
#### name
The `name` filter matches on task names.
```console
$ docker stack ps -f "name=voting_redis" voting
ID NAME IMAGE NODE DESIRED STATE CURRENTSTATE ERROR PORTS
w48spazhbmxc voting_redis.1 redis:alpine node2 Running Running 17 minutes ago
t72q3z038jeh voting_redis.2 redis:alpine node3 Running Running 17 minutes ago
```
#### node
The `node` filter matches on a node name or a node ID.
```console
$ docker stack ps -f "node=node1" voting
ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS
q7yik0ks1in6 voting_result.1 dockersamples/examplevotingapp_result:before node1 Running Running 18 minutes ago
tz6j82jnwrx7 voting_db.1 postgres:9.4 node1 Running Running 18 minutes ago
6jj1m02freg1 voting_visualizer.1 dockersamples/visualizer:stable node1 Running Running 18 minutes ago
```
#### desired-state
The `desired-state` filter can take the values `running`, `shutdown`, `ready` or `accepted`.
```console
$ docker stack ps -f "desired-state=running" voting
ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS
xim5bcqtgk1b voting_worker.1 dockersamples/examplevotingapp_worker:latest node2 Running Running 21 minutes ago

```
### Formatting
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 `stack 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:
```console
$ docker stack ps --format "{{.Name}}: {{.Image}}" voting
voting_worker.1: dockersamples/examplevotingapp_worker:latest
voting_result.1: dockersamples/examplevotingapp_result:before
voting_vote.1: dockersamples/examplevotingapp_vote:before
voting_db.1: postgres:9.4
voting_redis.1: redis:alpine
voting_visualizer.1: dockersamples/visualizer:stable
voting_vote.2: dockersamples/examplevotingapp_vote:before
voting_redis.2: redis:alpine
```
To list all tasks in JSON format, use the `json` directive:
```console
$ docker stack ps --format json myapp
{"CurrentState":"Preparing 23 seconds ago","DesiredState":"Running","Error":"","ID":"2ufjubh79tn0","Image":"localstack/localstack:latest","Name":"myapp_localstack.1","Node":"docker-desktop","Ports":""}
{"CurrentState":"Running 20 seconds ago","DesiredState":"Running","Error":"","ID":"roee387ngf5r","Image":"redis:6.0.9-alpine3.12","Name":"myapp_redis.1","Node":"docker-desktop","Ports":""}
{"CurrentState":"Preparing 13 seconds ago","DesiredState":"Running","Error":"","ID":"yte68ouq7glh","Image":"postgres:13.2-alpine","Name":"myapp_repos-db.1","Node":"docker-desktop","Ports":""}
```
### Do not map IDs to Names
The `--no-resolve` option shows IDs for task name, without mapping IDs to Names.
```console
$ docker stack ps --no-resolve voting

```
### Do not truncate output
When deploying a service, docker resolves the digest for the service's
image, and pins the service to that digest. The digest is not shown by
default, but is printed if `--no-trunc` is used. The `--no-trunc` option
also shows the non-truncated task IDs, and error-messages, as can be seen below:
```console
$ docker stack ps --no-trunc voting

```
### Only display task IDs
The `-q ` or `--quiet` option only shows IDs of the tasks in the stack.
This example outputs all task IDs of the "voting" stack;
```console
$ docker stack ps -q voting
xim5bcqtgk1b
q7yik0ks1in6
rx5yo0866nfx
tz6j82jnwrx7
w48spazhbmxc
6jj1m02freg1
kqgdmededccb
t72q3z038jeh
```
This option can be used to perform batch operations. For example, you can use
the task IDs as input for other commands, such as `docker inspect`. The
following example inspects all tasks of the "voting" stack;
```console
$ docker inspect $(docker stack ps -q voting)
[
{
"ID": "xim5bcqtgk1b1gk0krq1",
"Version": {
<...>
```
