# service ls
```Markdown
Usage: docker service ls [OPTIONS]

```
## Description
This command lists services are running in the swarm.
> **Note**
>
> This is a cluster management command, and must be executed on a swarm
> manager node. To learn about managers and workers, refer to the
> [Swarm mode section](https://docs.docker.com/engine/swarm/) in the
> documentation.
## Examples
On a manager node:
```console
$ docker service ls
ID NAME MODE REPLICAS IMAGE
c8wgl7q4ndfd frontend replicated 5/5 nginx:alpine
dmu1ept4cxcf redis replicated 3/3 redis:3.0.6
iwe3278osahj mongo global 7/7 mongo:3.3
hh08h9uu8uwr job replicated-job 1/1 (3/5 completed) nginx:latest
```
The `REPLICAS` column shows both the *actual* and *desired* number of tasks for
the service. If the service is in `replicated-job` or `global-job`, it will
additionally show the completion status of the job as completed tasks over
total tasks the job will execute.
### 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](service_ls.md#id)
* [label](service_ls.md#label)
* [mode](service_ls.md#mode)
* [name](service_ls.md#name)
#### id
The `id` filter matches all or part of a service's id.
```console
$ docker service ls -f "id=0bcjw"
ID NAME MODE REPLICAS IMAGE
0bcjwfh8ychr redis replicated 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:
```console
$ docker service ls --filter label=project
ID NAME MODE REPLICAS IMAGE
01sl1rp6nj5u frontend2 replicated 1/1 nginx:alpine
36xvvwwauej0 frontend replicated 5/5 nginx:alpine
74nzcxxjv6fq backend replicated 3/3 redis:3.0.6
```
The following filter matches only services with the `project` label with the
`project-a` value.
```console
$ docker service ls --filter label=project=project-a
ID NAME MODE REPLICAS IMAGE
36xvvwwauej0 frontend replicated 5/5 nginx:alpine
74nzcxxjv6fq backend replicated 3/3 redis:3.0.6
```
#### mode
The `mode` filter matches on the mode (either `replicated` or `global`) of a service.
The following filter matches only `global` services.
```console
$ docker service ls --filter mode=global
ID NAME MODE REPLICAS IMAGE
w7y0v2yrn620 top global 1/1 busybox
```
#### name
The `name` filter matches on all or part of a service's name.
The following filter matches services with a name containing `redis`.
```console
$ docker service ls --filter name=redis
ID NAME MODE REPLICAS IMAGE
0bcjwfh8ychr redis replicated 1/1 redis:3.0.6
```
### Formatting
The formatting options (`--format`) pretty-prints services output
using a Go template.
Valid placeholders for the Go template are listed below:
Placeholder | Description
------------|------------------------------------------------------------------------------------------
`.ID` | Service ID
`.Name` | Service name
`.Mode` | Service mode (replicated, global)
`.Replicas` | Service replicas
`.Image` | Service image
`.Ports` | Service ports published in ingress mode
When using the `--format` option, the `service ls` 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
`ID`, `Mode`, and `Replicas` entries separated by a colon (`:`) for all services:
```console
$ docker service ls --format "{{.ID}}: {{.Mode}} {{.Replicas}}"
0zmvwuiu3vue: replicated 10/10
fm6uf97exkul: global 5/5
```
