# stack services
```markdown
Usage: docker stack services [OPTIONS] STACK
List the services in the stack
Options:
-f, --filter filter Filter output based on conditions provided
--format string Pretty-print services using a Go template
--help Print usage
--kubeconfig string Kubernetes config file
--namespace string Kubernetes namespace to use
--orchestrator string Orchestrator to use (swarm|kubernetes|all)
-q, --quiet Only display IDs
```
## Description
Lists the services that are running as part of the specified stack.
> **Note**: This is a cluster management command. When using swarm as an orchestrator,
> this command 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
The following command shows all services in the `myapp` stack:
```bash
$ docker stack services myapp
ID NAME REPLICAS IMAGE COMMAND
7be5ei6sqeye myapp_web 1/1 nginx@sha256:23f809e7fd5952e7d5be065b4d3643fbbceccd349d537b62a123ef2201bc886f
dn7m7nhhfb9y myapp_db 1/1 mysql@sha256:a9a5b559f8821fe73d58c3606c812d1c044868d42c63817fa5125fd9d8b7b539
```
### 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.
The following command shows both the `web` and `db` services:
```bash
$ docker stack services --filter name=myapp_web --filter name=myapp_db myapp
ID NAME REPLICAS IMAGE COMMAND
7be5ei6sqeye myapp_web 1/1 nginx@sha256:23f809e7fd5952e7d5be065b4d3643fbbceccd349d537b62a123ef2201bc886f
dn7m7nhhfb9y myapp_db 1/1 mysql@sha256:a9a5b559f8821fe73d58c3606c812d1c044868d42c63817fa5125fd9d8b7b539
```
The currently supported filters are:
* id / ID (`--filter id=7be5ei6sqeye`, or `--filter ID=7be5ei6sqeye`)
* Swarm: supported
* Kubernetes: not supported
* label (`--filter label=key=value`)
* Swarm: supported
* Kubernetes: supported
* mode (`--filter mode=replicated`, or `--filter mode=global`)
* Swarm: not supported
* Kubernetes: supported
* name (`--filter name=myapp_web`)
* Swarm: supported
* Kubernetes: supported
* node (`--filter node=mynode`)
* Swarm: not supported
* Kubernetes: supported
* service (`--filter service=web`)
* Swarm: not supported
* Kubernetes: supported
### 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
When using the `--format` option, the `stack services` 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:
```bash
$ docker stack services --format "{{.ID}}: {{.Mode}} {{.Replicas}}"
0zmvwuiu3vue: replicated 10/10
fm6uf97exkul: global 5/5
```
