Rather than conflict with the unexposed task model, change the names of
the object-oriented task display to `docker <object> ps`. The command
works identically to `docker service tasks`. This change is superficial.
This provides a more sensical docker experience while not trampling on
the task model that may be introduced as a top-level command at a later
date.
The following is an example of the display using `docker service ps`
with a service named `condescending_cori`:
```
$ docker service ps condescending_cori
ID NAME SERVICE IMAGE LAST STATE DESIRED STATE NODE
e2cd9vqb62qjk38lw65uoffd2 condescending_cori.1 condescending_cori alpine Running 13 minutes ago Running 6c6d232a5d0e
```
The following shows the output for the node on which the command is
running:
```console
$ docker node ps self
ID NAME SERVICE IMAGE LAST STATE DESIRED STATE NODE
b1tpbi43k1ibevg2e94bmqo0s mad_kalam.1 mad_kalam apline Accepted 2 seconds ago Accepted 6c6d232a5d0e

# node ps
|
|
|
|
```markdown
|
|
Usage: docker node ps [OPTIONS] self|NODE
|
|
|
|
List tasks running on a node
|
|
|
|
Options:
|
|
-a, --all Display all instances
|
|
-f, --filter value Filter output based on conditions provided
|
|
--help Print usage
|
|
--no-resolve Do not map IDs to Names
|
|
```
|
|
|
|
Lists all the tasks on a Node that Docker knows about. You can filter using the `-f` or `--filter` flag. Refer to the [filtering](#filtering) section for more information about available filter options.
|
|
|
|
Example output:
|
|
|
|
$ docker node ps swarm-manager1
|
|
ID NAME SERVICE IMAGE LAST STATE DESIRED STATE NODE

## 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.
|
|
|
|
$ docker node ps -f name=redis swarm-manager1
|
|
ID NAME SERVICE IMAGE LAST STATE DESIRED STATE NODE
|
|
7q92v0nr1hcgts2amcjyqg3pq redis.1 redis redis:3.0.6 Running 5 hours Running swarm-manager1
|
|
b465edgho06e318egmgjbqo4o redis.6 redis redis:3.0.6 Running 29 seconds Running swarm-manager1
|
|
bg8c07zzg87di2mufeq51a2qp redis.7 redis redis:3.0.6 Running 5 seconds Running swarm-manager1
|
|
dkkual96p4bb3s6b10r7coxxt redis.9 redis redis:3.0.6 Running 5 seconds Running swarm-manager1
|
|
0tgctg8h8cech4w0k0gwrmr23 redis.10 redis redis:3.0.6 Running 5 seconds Running swarm-manager1
|
|
|
|
|
|
#### id
|
|
|
|
The `id` filter matches a task's id.
|
|
|
|
$ docker node ps -f id=bg8c07zzg87di2mufeq51a2qp swarm-manager1
|
|
ID NAME SERVICE IMAGE LAST STATE DESIRED STATE NODE
|
|
bg8c07zzg87di2mufeq51a2qp redis.7 redis redis:3.0.6 Running 5 seconds Running swarm-manager1
|
|
|
|
|
|
#### 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"
|
|
ID NAME SERVICE IMAGE LAST STATE DESIRED STATE NODE
|
|
b465edgho06e318egmgjbqo4o redis.6 redis redis:3.0.6 Running 10 minutes Running swarm-manager1
|
|
bg8c07zzg87di2mufeq51a2qp redis.7 redis redis:3.0.6 Running 9 minutes Running swarm-manager1
|
|
```
|
|
|
|
|
|
#### desired-state
|
|
|
|
The `desired-state` filter can take the values `running` and `accepted`.
