## Description
|
|
|
|
Lists the tasks that are running as part of the specified services. This command
|
|
has to be run targeting a manager node.
|
|
|
|
## Examples
|
|
|
|
### List the tasks that are part of a service
|
|
|
|
The following command shows all the tasks that are part of the `redis` service:
|
|
|
|
```bash
|
|
$ docker service ps redis
|
|
|
|
ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS
|
|
0qihejybwf1x redis.1 redis:3.0.5 manager1 Running Running 8 seconds
|
|
bk658fpbex0d redis.2 redis:3.0.5 worker2 Running Running 9 seconds
|
|
5ls5s5fldaqg redis.3 redis:3.0.5 worker1 Running Running 9 seconds
|
|
8ryt076polmc redis.4 redis:3.0.5 worker1 Running Running 9 seconds
|
|
1x0v8yomsncd redis.5 redis:3.0.5 manager1 Running Running 8 seconds
|
|
71v7je3el7rr redis.6 redis:3.0.5 worker2 Running Running 9 seconds
|
|
4l3zm9b7tfr7 redis.7 redis:3.0.5 worker2 Running Running 9 seconds
|
|
9tfpyixiy2i7 redis.8 redis:3.0.5 worker1 Running Running 9 seconds
|
|
3w1wu13yupln redis.9 redis:3.0.5 manager1 Running Running 8 seconds
|
|
8eaxrb2fqpbn redis.10 redis:3.0.5 manager1 Running Running 8 seconds
|
|
```
|
|
|
|
In addition to _running_ tasks, the output also shows the task history. For
|
|
example, after updating the service to use the `redis:3.0.6` image, the output
|
|
may look like this:
|
|
|
|
```bash
|
|
$ docker service ps redis
|
|
|
|
ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS
|
|
50qe8lfnxaxk redis.1 redis:3.0.6 manager1 Running Running 6 seconds ago
|
|

|
|

|
|
nvjljf7rmor4 \_ redis.2 redis:3.0.6 worker2 Shutdown Rejected 23 seconds ago "No such image: redis@sha256:6…"
|
|
vtiuz2fpc0yb \_ redis.2 redis:3.0.5 worker2 Shutdown Shutdown 1 second ago
|
|
jnarweeha8x4 redis.3 redis:3.0.6 worker1 Running Running 3 seconds ago
|
|
vs448yca2nz4 \_ redis.3 redis:3.0.5 worker1 Shutdown Shutdown 4 seconds ago
|
|
jf1i992619ir redis.4 redis:3.0.6 worker1 Running Running 10 seconds ago
|
|
blkttv7zs8ee \_ redis.4 redis:3.0.5 worker1 Shutdown Shutdown 11 seconds ago
|
|
```
|
|
|
|
The number of items in the task history is determined by the
|
|
`--task-history-limit` option that was set when initializing the swarm. You can
|
|
change the task history retention limit using the
|
|
[`docker swarm update`](swarm_update.md) command.
|
|
|
|
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 ID, and error-messages, as can be seen below;
|
|
|
|
```bash
|
|
$ docker service ps --no-trunc redis
|
|
|
|

|
|
```
|
|
|
|
### Filtering
|
|
|
|
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.
|
|
|
|
```bash
|
|
$ docker service ps -f "id=8" redis
|
|
|
|
ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS
|
|
8ryt076polmc redis.4 redis:3.0.6 worker1 Running Running 9 seconds
|
|
8eaxrb2fqpbn redis.10 redis:3.0.6 manager1 Running Running 8 seconds
|
|
```
|
|
|
|
#### name
|
|
|
|
The `name` filter matches on task names.
|
|
|
|
```bash
|
|
$ docker service ps -f "name=redis.1" redis
|
|
ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS
|
|
qihejybwf1x5 redis.1 redis:3.0.6 manager1 Running Running 8 seconds
|
|
```
|
|
|
|
|
|
#### node
|
|
|
|
The `node` filter matches on a node name or a node ID.
|
|
|
|
```bash
|
|
$ docker service ps -f "node=manager1" redis
|
|
ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS
|
|
0qihejybwf1x redis.1 redis:3.0.6 manager1 Running Running 8 seconds
|
|
1x0v8yomsncd redis.5 redis:3.0.6 manager1 Running Running 8 seconds
|
|
3w1wu13yupln redis.9 redis:3.0.6 manager1 Running Running 8 seconds
|
|
8eaxrb2fqpbn redis.10 redis:3.0.6 manager1 Running Running 8 seconds
|
|
```
|
|
|
|
#### desired-state
|
|
|
|
The `desired-state` filter can take the values `running`, `shutdown`, or `accepted`.
|
|
|
|
### Formatting
|
|
|
|
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 `service 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:
|
|
|
|
```bash
|
|
$ docker service ps --format "{{.Name}}: {{.Image}}" top
|
|
top.1: busybox
|
|
top.2: busybox
|
|
top.3: busybox
|
|
```
