stack services
Usage: docker stack services [OPTIONS] STACK
List the services in the stack
Options:
-f, --filter filter Filter output based on conditions provided
--format string Pretty-print services using a Go template
--help Print usage
-q, --quiet Only display IDs
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}}"
