Description

Lists the services that are running as part of the specified stack.

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.

Examples

The following command shows all services in the myapp stack:

$ 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:

$ 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)
  • label (--filter label=key=value)
  • mode (--filter mode=replicated, or --filter mode=global)
    • Swarm: not supported
  • name (--filter name=myapp_web)
  • node (--filter node=mynode)
    • Swarm: not supported
  • service (--filter service=web)
    • Swarm: not 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:

$ docker stack services --format "{{.ID}}: {{.Mode}} {{.Replicas}}"
