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

Warning: this command is part of the Swarm management feature introduced in Docker 1.12, and might be subject to non backward-compatible changes.
node ls
Usage: docker node ls [OPTIONS]
List nodes in the swarm
Aliases:
ls, list
Options:
-f, --filter value Filter output based on conditions provided
--help Print usage
-q, --quiet Only display IDs
Lists all the nodes that the Docker Swarm manager knows about. You can filter using the -f or --filter flag. Refer to the filtering section for more information about available filter options.
Example output:
$ docker node ls
ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS
1bcef6utixb0l0ca7gxuivsj0 swarm-worker2 Ready Active
38ciaotwjuritcdtn9npbnkuz swarm-worker1 Ready Active
e216jshn25ckzbvmwlnh5jr3g * swarm-manager1 Ready Active Leader
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
- id
- label
name
The name filter matches on all or part of a node name.
The following filter matches the node with a name equal to swarm-master string.
$ docker node ls -f name=swarm-manager1
ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS
e216jshn25ckzbvmwlnh5jr3g * swarm-manager1 Ready Active Leader
id
The id filter matches all or part of a node's id.
$ docker node ls -f id=1
ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS
1bcef6utixb0l0ca7gxuivsj0 swarm-worker2 Ready Active
label
The label filter matches tasks based on the presence of a label alone or a label and a
value.
The following filter matches nodes with the usage label regardless of its value.
$ docker node ls -f "label=foo"
ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS
1bcef6utixb0l0ca7gxuivsj0 swarm-worker2 Ready Active
