ps

Usage: docker ps [OPTIONS]

List containers

  -a, --all=false       Show all containers (default shows just running)
  --before=""           Show only container created before Id or Name
  -f, --filter=[]       Filter output based on conditions provided
  -l, --latest=false    Show the latest created container, include non-running
  -n=-1                 Show n last created containers, include non-running
  --no-trunc=false      Don't truncate output
  -q, --quiet=false     Only display numeric IDs
  -s, --size=false      Display total file sizes
  --since=""            Show created since Id or Name, include non-running
  --format=[]       Pretty-print containers using a Go template

Running docker ps --no-trunc showing 2 linked containers.

$ docker ps
CONTAINER ID        IMAGE                        COMMAND                CREATED              STATUS              PORTS               NAMES
4c01db0b339c        ubuntu:12.04                 bash                   17 seconds ago       Up 16 seconds       3300-3310/tcp       webapp

docker ps will show only running containers by default. To see all containers: docker ps -a

docker ps will group exposed ports into a single range if possible. E.g., a container that exposes TCP ports 100, 101, 102 will display 100-102/tcp in the PORTS column.

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")

The currently supported filters are:

• id (container's id)
• label (label=<key> or label=<key>=<value>)
• name (container's name)
• exited (int - the code of exited containers. Only useful with --all)
• status (created|restarting|running|paused|exited)

Successfully exited containers

$ docker ps -a --filter 'exited=0'
CONTAINER ID        IMAGE             COMMAND                CREATED             STATUS                   PORTS                      NAMES
ea09c3c82f6e        registry:latest   /srv/run.sh            2 weeks ago         Exited (0) 2 weeks ago   127.0.0.1:5000->5000/tcp   desperate_leakey
106ea823fe4e        fedora:latest     /bin/sh -c 'bash -l'   2 weeks ago         Exited (0) 2 weeks ago                              determined_albattani
48ee228c9464        fedora:20         bash                   2 weeks ago         Exited (0) 2 weeks ago                              tender_torvalds

This shows all the containers that have exited with status of '0'

Formatting

The formatting option (--format) will pretty-print container output using a Go template.

Valid placeholders for the Go template are listed below:

Placeholder	Description
.ID	Container ID
.Image	Image ID
.Command	Quoted command
.CreatedAt	Time when the container was created.
.RunningFor	Elapsed time since the container was started.
.Ports	Exposed ports.
.Status	Container status.
.Size	Container disk size.
.Labels	All labels asigned to the container.
.Label	Value of a specific label for this container. For example {{.Label "com.docker.swarm.cpu"}}

When using the --format option, the ps command will either output the data exactly as the template declares or, when using the table directive, will include column headers as well.

The following example uses a template without headers and outputs the ID and Command entries separated by a colon for all running containers:

$ docker ps --format "{{.ID}}: {{.Command}}"
a87ecb4f327c: /bin/sh -c #(nop) MA
01946d9d34d8: /bin/sh -c #(nop) MA
c1d3b0166030: /bin/sh -c yum -y up
41d50ecd2f57: /bin/sh -c #(nop) MA

To list all running containers with their labels in a table format you can use:

$ docker ps --format "table {{.ID}}\t{{.Labels}}"
CONTAINER ID        LABELS
a87ecb4f327c        com.docker.swarm.node=ubuntu,com.docker.swarm.storage=ssd
01946d9d34d8
c1d3b0166030        com.docker.swarm.node=debian,com.docker.swarm.cpu=6
41d50ecd2f57        com.docker.swarm.node=fedora,com.docker.swarm.cpu=3,com.docker.swarm.storage=ssd
