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

The docker ps command only shows running containers by default. To see all containers, use the -a (or --all) flag:

$ docker ps -a

docker ps groups exposed ports into a single range if possible. E.g., a container that exposes TCP ports 100, 101, 102 displays 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|removing|paused|exited|dead)
  • ancestor (<image-name>[:<tag>], <image id> or <image@digest>) - filters containers that were created from the given image or a descendant.
  • before (container's id or name) - filters containers created before given id or name
  • since (container's id or name) - filters containers created since given id or name
  • isolation (default|process|hyperv) (Windows daemon only)
  • volume (volume name or mount point) - filters containers that mount volumes.
  • network (network id or name) - filters containers connected to the provided network
  • health (starting|healthy|unhealthy|none) - filters containers based on healthcheck status

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
715ebfcee040        busybox             "top"               3 seconds ago       Up 1 second                             i_am_nostalgic
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

Killed containers

You can use a filter to locate containers that exited with status of 137 meaning a SIGKILL(9) killed them.

$ docker ps -a --filter 'exited=137'
CONTAINER ID        IMAGE               COMMAND                CREATED             STATUS                       PORTS               NAMES
b3e1c0ed5bfe        ubuntu:latest       "sleep 1000"           12 seconds ago      Exited (137) 5 seconds ago                       grave_kowalevski
a2eb5558d669        redis:latest        "/entrypoint.sh redi   2 hours ago         Exited (137) 2 hours ago                         sharp_lalande

Any of these events result in a 137 status:

  • the init process of the container is killed manually
  • docker kill kills the container
  • Docker daemon restarts which kills all running containers

Status

The status filter matches containers by status. You can filter using created, restarting, running, removing, paused, exited and dead. 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 its 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

Before

The before filter shows only containers created before the container with given id or name. For example, having these containers created:

$ docker ps

CONTAINER ID        IMAGE       COMMAND       CREATED              STATUS              PORTS              NAMES
9c3527ed70ce        busybox     "top"         14 seconds ago       Up 15 seconds                          desperate_dubinsky
4aace5031105        busybox     "top"         48 seconds ago       Up 49 seconds                          focused_hamilton
6e63f6ff38b0        busybox     "top"         About a minute ago   Up About a minute                      distracted_fermat

Filtering with before would give:

$ docker ps -f before=9c3527ed70ce

CONTAINER ID        IMAGE       COMMAND       CREATED              STATUS              PORTS              NAMES
4aace5031105        busybox     "top"         About a minute ago   Up About a minute                      focused_hamilton
6e63f6ff38b0        busybox     "top"         About a minute ago   Up About a minute                      distracted_fermat

Since

The since filter shows only containers created since the container with given id or name. For example, with the same containers as in before filter:

$ docker ps -f since=6e63f6ff38b0

CONTAINER ID        IMAGE       COMMAND       CREATED             STATUS              PORTS               NAMES
9c3527ed70ce        busybox     "top"         10 minutes ago      Up 10 minutes                           desperate_dubinsky
4aace5031105        busybox     "top"         10 minutes ago      Up 10 minutes                           focused_hamilton

Volume

The volume filter shows only containers that mount a specific volume or have a volume mounted in a specific path:

$ docker ps --filter volume=remote-volume --format "table {{.ID}}\t{{.Mounts}}"
CONTAINER ID        MOUNTS
9c3527ed70ce        remote-volume

$ docker ps --filter volume=/data --format "table {{.ID}}\t{{.Mounts}}"
CONTAINER ID        MOUNTS
9c3527ed70ce        remote-volume
{% endraw %}```

#### Network

The `network` filter shows only containers that are connected to a network with
a given name or id.

The following filter matches all containers that are connected to a network
with a name containing `net1`.

```bash
$ docker run -d --net=net1 --name=test1 ubuntu top
$ docker run -d --net=net2 --name=test2 ubuntu top

$ docker ps --filter network=net1

CONTAINER ID        IMAGE       COMMAND       CREATED             STATUS              PORTS               NAMES
9d4893ed80fe        ubuntu      "top"         10 minutes ago      Up 10 minutes                           test1

The network filter matches on both the network's name and id. The following example shows all containers that are attached to the net1 network, using the network id as a filter;

{% raw %}
$ docker network inspect --format "{{.ID}}" net1
{% endraw %}

8c0b4110ae930dbe26b258de9bc34a03f98056ed6f27f991d32919bfe401d7c5

$ docker ps --filter network=8c0b4110ae930dbe26b258de9bc34a03f98056ed6f27f991d32919bfe401d7c5

CONTAINER ID        IMAGE       COMMAND       CREATED             STATUS              PORTS               NAMES
9d4893ed80fe        ubuntu      "top"         10 minutes ago      Up 10 minutes                           test1

Formatting

The formatting option (--format) pretty-prints 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 '{% raw %}{{.Label "com.docker.swarm.cpu"}}{% endraw %}'
.Mounts Names of the volumes mounted in this container.
.Networks Names of the networks attached to this container.

When using the --format option, the ps 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 and Command entries separated by a colon for all running containers:

{% raw %}
$ docker ps --format "{{.ID}}: {{.Command}}"
{% endraw %}

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:

{% raw %}
$ docker ps --format "table {{.ID}}\t{{.Labels}}"
{% endraw %}
