  description: Pretty-print stacks using a Go template
examples: |-
  The following command shows all stacks and some additional information:

  ```bash
  $ docker stack ls

  ID                 SERVICES
  vossibility-stack  6
  myapp              2
  ```

  ### Formatting

  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 |

  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:

  ```bash
  $ docker stack ls --format "{{.Name}}: {{.Services}}"
  web-server: 1
  web-cache: 4
  ```
