Extended description

This command when run targeting a manager, lists services are running in the swarm.

Examples

On a manager node:

$ docker service ls

ID            NAME      MODE        REPLICAS    IMAGE
c8wgl7q4ndfd  frontend  replicated  5/5         nginx:alpine
dmu1ept4cxcf  redis     replicated  3/3         redis:3.0.6
iwe3278osahj  mongo     global      7/7         mongo:3.3

The REPLICAS column shows both the actual and desired number of tasks for the service.

Filtering

The filtering flag (-f or --filter) format is of “key=value”. If there is more than one filter, then pass multiple flags (e.g., --filter "foo=bar" --filter "bif=baz")

The currently supported filters are:

id

The id filter matches all or part of a service’s id.

$ docker service ls -f "id=0bcjw"
ID            NAME   MODE        REPLICAS  IMAGE
0bcjwfh8ychr  redis  replicated  1/1       redis:3.0.6

label

The label filter matches services based on the presence of a label alone or a label and a value.

The following filter matches all services with a project label regardless of its value:

$ docker service ls --filter label=project
ID            NAME       MODE        REPLICAS  IMAGE
01sl1rp6nj5u  frontend2  replicated  1/1       nginx:alpine
36xvvwwauej0  frontend   replicated  5/5       nginx:alpine
74nzcxxjv6fq  backend    replicated  3/3       redis:3.0.6

The following filter matches only services with the project label with the project-a value.

$ docker service ls --filter label=project=project-a
ID            NAME      MODE        REPLICAS  IMAGE
36xvvwwauej0  frontend  replicated  5/5       nginx:alpine
74nzcxxjv6fq  backend   replicated  3/3       redis:3.0.6

mode

The mode filter matches on the mode (either replicated or global) of a service.

The following filter matches only global services.

$ docker service ls --filter mode=global
ID                  NAME                MODE                REPLICAS            IMAGE
w7y0v2yrn620        top                 global              1/1                 busybox

name

The name filter matches on all or part of a service’s name.

The following filter matches services with a name containing redis.

$ docker service ls --filter name=redis
ID            NAME   MODE        REPLICAS  IMAGE
0bcjwfh8ychr  redis  replicated  1/1       redis:3.0.6

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
`.Ports`	Service ports published in ingress mode

When using the --format option, the service ls 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 service ls --format "{{.ID}}: {{.Mode}} {{.Replicas}}"
