Option	Default	Description
`--format`		Format output using a custom template: 'table': Print output in table format with column headers (default) 'table TEMPLATE': Print output in table format using the given Go template 'json': Print in JSON format 'TEMPLATE': Print output using the given Go template. Refer to https://docs.docker.com/go/formatting/ for more information about formatting output with templates

Examples

The following command shows all stacks and some additional information:

$ docker stack ls

ID                 SERVICES            ORCHESTRATOR
myapp              2                   Kubernetes
vossibility-stack  6                   Swarm

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:

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

To list all stacks in JSON format, use the json directive:

$ docker stack ls --format json
{"Name":"myapp","Namespace":"","Orchestrator":"Swarm","Services":"3"}
