|---|---|---|---|
--format |
string |
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 |
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 in the documentation.
The following command shows all stacks and some additional information:
$ docker stack ls
ID SERVICES ORCHESTRATOR
myapp 2 Kubernetes
vossibility-stack 6 SwarmThe 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: 4To list all stacks in JSON format, use the json directive:
$ docker stack ls --format json
{"Name":"myapp","Namespace":"","Orchestrator":"Swarm","Services":"3"}
