# ps
Usage: docker ps [OPTIONS]
List containers
-a, --all=false Show all containers (default shows just running)
-f, --filter=[] Filter output based on conditions provided
--format=[] Pretty-print containers using a Go template
--help=false Print usage
-l, --latest=false Show the latest created container (includes all states)
-n=-1 Show n last created containers (includes all states)
--no-trunc=false Don't truncate output
-q, --quiet=false Only display numeric IDs
-s, --size=false Display total file sizes
Running `docker ps --no-trunc` showing 2 linked containers.
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

`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.
* 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}}"
