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>

This command when run targeting a manager, lists services are running in the swarm.
On a manager node:
ID NAME REPLICAS IMAGE COMMAND
c8wgl7q4ndfd frontend 5/5 nginx:alpine
dmu1ept4cxcf redis 3/3 redis:3.0.6
The REPLICAS column shows both the actual and desired number of tasks for
the service.
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:
ID
The id filter matches all or part of a service's id.
$ docker service ls -f "id=0bcjw"
ID NAME REPLICAS IMAGE COMMAND
0bcjwfh8ychr redis 1/1 redis:3.0.6
Label
The label filter matches services based on the presence of a label alone or
a label and a value.
The following filter matches all services with a project label regardless of
its value:
$ docker service ls --filter label=project
ID NAME REPLICAS IMAGE COMMAND
01sl1rp6nj5u frontend2 1/1 nginx:alpine
36xvvwwauej0 frontend 5/5 nginx:alpine
74nzcxxjv6fq backend 3/3 redis:3.0.6
The following filter matches only services with the project label with the
project-a value.
$ docker service ls --filter label=project=project-a
ID NAME REPLICAS IMAGE COMMAND
36xvvwwauej0 frontend 5/5 nginx:alpine
74nzcxxjv6fq backend 3/3 redis:3.0.6
Name
The name filter matches on all or part of a tasks's name.
The following filter matches services with a name containing redis.
$ docker service ls --filter name=redis
ID NAME REPLICAS IMAGE COMMAND
0bcjwfh8ychr redis 1/1 redis:3.0.6
