# service tasks
```Markdown
Usage: docker service tasks [OPTIONS] SERVICE
List the tasks of a service
Options:
-a, --all Display all tasks
-f, --filter value Filter output based on conditions provided
--help Print usage
-n, --no-resolve Do not map IDs to Names
```
Lists the tasks that are running as part of the specified service. This command
has to be run targeting a manager node.
## Examples
### Listing 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 tasks redis
ID NAME SERVICE IMAGE LAST STATE DESIRED STATE NODE
0qihejybwf1x5vqi8lgzlgnpq redis.1 redis redis:3.0.6 Running 8 seconds Running manager1
bk658fpbex0d57cqcwoe3jthu redis.2 redis redis:3.0.6 Running 9 seconds Running worker2

8eaxrb2fqpbnv9x30vr06i6vt redis.10 redis redis:3.0.6 Running 8 seconds Running manager1
```
## 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 type=custom -f type=builtin` returns both `custom` and `builtin` networks.
The currently supported filters are:
* [id](#id)
* [name](#name)
#### ID
The `id` filter matches on all or a prefix of a task's ID.
```bash
$ docker service tasks -f "id=8" redis
ID NAME SERVICE IMAGE LAST STATE DESIRED STATE NODE
8ryt076polmclyihzx67zsssj redis.4 redis redis:3.0.6 Running 4 minutes Running worker1
8eaxrb2fqpbnv9x30vr06i6vt redis.10 redis redis:3.0.6 Running 4 minutes Running manager1
```
#### Name
The `name` filter matches on task names.
```bash
$ docker service tasks -f "name=redis.1" redis
ID NAME SERVICE IMAGE DESIRED STATE LAST STATE NODE
0qihejybwf1x5vqi8lgzlgnpq redis.1 redis redis:3.0.6 Running Running 8 seconds manager1
```
