| ## 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 | |

| ``` | |
| ### <a name="filter"></a> Filtering (--filter) | |
| 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 | |

| ``` | |
| ### <a name="format"></a> 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 `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":""} | |
| ``` | |
| ### <a name="no-resolve"></a> Do not map IDs to Names (--no-resolve) | |
| The `--no-resolve` option shows IDs for task name, without mapping IDs to Names. | |
| ```console | |
| $ docker stack ps --no-resolve voting | |
| ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS | |

| ``` | |
| ### <a name="no-trunc"></a> Do not truncate output (--no-trunc) | |
| 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 | |
| ID NAME IMAGE NODE DESIRED STATE CURREN STATE ERROR PORTS | |

| ``` | |
| ### <a name="quiet"></a> Only display task IDs (-q, --quiet) | |
| 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": { | |
| <...> | |
| ``` | |
