  --since=""            Show created since Id or Name, include non-running

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)
  • ancestor (<image-name>[:<tag>], <image id> or <image@digest>) - filters containers that were created from the given image or a descendant.

Label

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

The following filter matches containers with the color label regardless of its value.

$ docker ps --filter "label=color"
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
673394ef1d4c        busybox             "top"               47 seconds ago      Up 45 seconds                           nostalgic_shockley
d85756f57265        busybox             "top"               52 seconds ago      Up 51 seconds                           high_albattani

The following filter matches containers with the color label with the blue value.

$ docker ps --filter "label=color=blue"
CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS               NAMES
d85756f57265        busybox             "top"               About a minute ago   Up About a minute                       high_albattani

Name

The name filter matches on all or part of a container's name.

The following filter matches all containers with a name containing the nostalgic_stallman string.

$ docker ps --filter "name=nostalgic_stallman"
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
9b6247364a03        busybox             "top"               2 minutes ago       Up 2 minutes                            nostalgic_stallman

You can also filter for a substring in a name as this shows:

$ docker ps --filter "name=nostalgic"
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

9b6247364a03        busybox             "top"               7 minutes ago       Up 7 minutes                            nostalgic_stallman
673394ef1d4c        busybox             "top"               38 minutes ago      Up 38 minutes                           nostalgic_shockley

Exited

The exited filter matches containers by exist status code. For example, to filter for containers that have exited successfully:

$ 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

Status

The status filter matches containers by status. You can filter using created, restarting, running, paused and exited. For example, to filter for running containers:

$ docker ps --filter status=running
CONTAINER ID        IMAGE                  COMMAND             CREATED             STATUS              PORTS               NAMES
715ebfcee040        busybox                "top"               16 minutes ago      Up 16 minutes                           i_am_nostalgic
d5c976d3c462        busybox                "top"               23 minutes ago      Up 23 minutes                           top
9b6247364a03        busybox                "top"               24 minutes ago      Up 24 minutes                           nostalgic_stallman

To filter for paused containers:

$ docker ps --filter status=paused
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                      PORTS               NAMES
673394ef1d4c        busybox             "top"               About an hour ago   Up About an hour (Paused)                       nostalgic_shockley

Ancestor

The ancestor filter matches containers based on its image or a descendant of it. The filter supports the following image representation:

  • image
  • image:tag
  • image:tag@digest
  • short-id
  • full-id

If you don't specify a tag, the latest tag is used. For example, to filter for containers that use the latest ubuntu image:

$ docker ps --filter ancestor=ubuntu
CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS               NAMES
919e1179bdb8        ubuntu-c1           "top"               About a minute ago   Up About a minute                       admiring_lovelace
5d1e4a540723        ubuntu-c2           "top"               About a minute ago   Up About a minute                       admiring_sammet
82a598284012        ubuntu              "top"               3 minutes ago        Up 3 minutes                            sleepy_bose
bab2a34ba363        ubuntu              "top"               3 minutes ago        Up 3 minutes                            focused_yonath

Match containers based on the ubuntu-c1 image which, in this case, is a child of ubuntu:

$ docker ps --filter ancestor=ubuntu-c1
CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS               NAMES
919e1179bdb8        ubuntu-c1           "top"               About a minute ago   Up About a minute                       admiring_lovelace

Match containers based on the ubuntu version 12.04.5 image:

$ docker ps --filter ancestor=ubuntu:12.04.5
CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS               NAMES
82a598284012        ubuntu:12.04.5      "top"               3 minutes ago        Up 3 minutes                            sleepy_bose

The following matches containers based on the layer d0e008c6cf02 or an image that have this layer in it's layer stack.

$ docker ps --filter ancestor=d0e008c6cf02
CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS               NAMES
82a598284012        ubuntu:12.04.5      "top"               3 minutes ago        Up 3 minutes                            sleepy_bose

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.
.Names Container names.
.Labels All labels assigned 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
