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 e2cd9vqb62qjk38lw65uoffd2 condescending_cori.1 condescending_cori alpine Running 12 minutes ago Running 6c6d232a5d0e 4x609m5o0qyn0kgpzvf0ad8x5 furious_davinci.1 furious_davinci redis Running 32 minutes ago Running 6c6d232a5d0e ``` Signed-off-by: Stephen J Day <stephen.day@docker.com>

|
|
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.
|
|
|
|
```bash
|
|
$ 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.
|
|
|
|
```bash
|
|
$ 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.
|
|
|
|
```bash
|
|
$ docker node ls -f "label=foo"
|
|
|
|
ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS
|
|
1bcef6utixb0l0ca7gxuivsj0 swarm-worker2 Ready Active
|
|
```
