Examples

The following command shows all services in the myapp stack:

ID            NAME            REPLICAS  IMAGE                                                                          COMMAND

dn7m7nhhfb9y  myapp_db        1/1       mysql@sha256:a9a5b559f8821fe73d58c3606c812d1c044868d42c63817fa5125fd9d8b7b539

Filtering (--filter)

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

Format the output (--format)

The formatting options (--format) pretty-prints services output using a Go template.

Valid placeholders for the Go template are listed below:

PlaceholderDescription
.IDService ID
.NameService name
.ModeService mode (replicated, global)
.ReplicasService replicas
.ImageService 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}}"

0zmvwuiu3vue: replicated 10/10
fm6uf97exkul: global 5/5

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

$ docker stack services ls --format json
