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>orlabel=<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. - isolation (default|process|hyperv) (Windows daemon only)
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 seconds 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
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}}"
