Keep frontmatter for docker, dockerd and index markdown files. Also needs to move cli.md > docker.md before generation and then move it back because cli.md is needed for yaml generation on docs website: https://github.com/docker/cli/pull/3924#discussion_r1059986605 Signed-off-by: Kevin Alvarez <crazy-max@users.noreply.github.com> Signed-off-by: Sebastiaan van Stijn <github@gone.nl>

## Description
|
|
|
|
Lists the stacks.
|
|
|
|
> **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
|
|
|
|
The following command shows all stacks and some additional information:
|
|
|
|
```console
|
|
$ docker stack ls
|
|
|
|
ID SERVICES ORCHESTRATOR
|
|
myapp 2 Kubernetes
|
|
vossibility-stack 6 Swarm
|
|
```
|
|
|
|
### <a name="format"></a> Format the output (--format)
|
|
|
|
The formatting option (`--format`) pretty-prints stacks using a Go template.
|
|
|
|
Valid placeholders for the Go template are listed below:
|
|
|
|
| Placeholder | Description |
|
|
|-----------------|--------------------|
|
|
| `.Name` | Stack name |
|
|
| `.Services` | Number of services |
|
|
| `.Orchestrator` | Orchestrator name |
|
|
| `.Namespace` | Namespace |
|
|
|
|
When using the `--format` option, the `stack ls` command either outputs
|
|
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 `Services` entries separated by a colon (`:`) for all stacks:
|
|
|
|
```console
|
|
$ docker stack ls --format "{{.Name}}: {{.Services}}"
|
|
web-server: 1
|
|
web-cache: 4
|
|
```
|
|
|
|
To list all stacks in JSON format, use the `json` directive:
|
|
|
|
```console
|
|
$ docker stack ls --format json
|
|
{"Name":"myapp","Namespace":"","Orchestrator":"Swarm","Services":"3"}
|
|
```
|
