### Do not truncate output (--no-trunc)
Running `docker ps --no-trunc` showing 2 linked containers.
```console
$ docker ps --no-trunc
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
ca5534a51dd04bbcebe9b23ba05f389466cf0c190f1f8f182d7eea92a9671d00 ubuntu:24.04 bash 17 seconds ago Up 16 seconds 3300-3310/tcp webapp
9ca9747b233100676a48cc7806131586213fa5dab86dd1972d6a8732e3a84a4d crosbymichael/redis:latest /redis-server --dir 33 minutes ago Up 33 minutes 6379/tcp redis,webapp/db
```
### Show both running and stopped containers (-a, --all)
The `docker ps` command only shows running containers by default. To see all
containers, use the `--all` (or `-a`) flag:
```console
$ 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.
### Show disk usage by container (--size)
The `docker ps --size` (or `-s`) command displays two different on-disk-sizes for each container:
```console
$ docker ps --size
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES SIZE
e90b8831a4b8 nginx "/bin/bash -c 'mkdir " 11 weeks ago Up 4 hours my_nginx 35.58 kB (virtual 109.2 MB)
00c6131c5e30 telegraf:1.5 "/entrypoint.sh" 11 weeks ago Up 11 weeks my_telegraf 0 B (virtual 209.5 MB)
```
* The "size" information shows the amount of data (on disk) that is used for the _writable_ layer of each container
* The "virtual size" is the total amount of disk-space used for the read-only _image_ data used by the container and the writable layer.
For more information, refer to the [container size on disk](https://docs.docker.com/storage/storagedriver/#container-size-on-disk) section.
### Filtering (--filter)
The `--filter` (or `-f`) flag 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:
| Filter | Description |
|:----------------------|:-------------------------------------------------------------------------------------------------------------------------------------|
| `id` | Container's ID |
| `name` | Container's name |
| `label` | An arbitrary string representing either a key or a key-value pair. Expressed as `` or `=` |
| `exited` | An integer representing the container's exit code. Only useful with `--all`. |
| `status` | One of `created`, `restarting`, `running`, `removing`, `paused`, `exited`, or `dead` |
| `ancestor` | Filters containers which share a given image as an ancestor. Expressed as `[:]`, ``, or `` |
| `before` or `since` | Filters containers created before or after a given container ID or name |
| `volume` | Filters running containers which have mounted a given volume or bind mount. |
| `network` | Filters running containers connected to a given network. |
| `publish` or `expose` | Filters containers which publish or expose a given port. Expressed as `[/]` or `/[]` |
| `health` | Filters containers based on their healthcheck status. One of `starting`, `healthy`, `unhealthy` or `none`. |
| `isolation` | Windows daemon only. One of `default`, `process`, or `hyperv`. |
| `is-task` | Filters containers that are a "task" for a service. Boolean option (`true` or `false`) |
#### 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.
```console
$ 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.
```console
$ 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.
```console
$ 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:
```console
$ 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:
```console
$ 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
```
#### Filter by exit signal
You can use a filter to locate containers that exited with status of `137`
meaning a `SIGKILL(9)` killed them.
```console
$ 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. The possible values for the container status are:
| Status | Description |
| :----------- | :---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `created` | A container that has never been started. |
| `running` | A running container, started by either `docker start` or `docker run`. |
| `paused` | A paused container. See `docker pause`. |
| `restarting` | A container which is starting due to the designated restart policy for that container. |
| `exited` | A container which is no longer running. For example, the process inside the container completed or the container was stopped using the `docker stop` command. |
| `removing` | A container which is in the process of being removed. See `docker rm`. |
| `dead` | A "defunct" container; for example, a container that was only partially removed because resources were kept busy by an external process. `dead` containers cannot be (re)started, only removed. |
For example, to filter for `running` containers:
```console
$ 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:
```console
$ 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:
```console
$ 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`:
```console
$ 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 `24.04` image:
```console
$ docker ps --filter ancestor=ubuntu:24.04
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
82a598284012 ubuntu:24.04 "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.
```console
$ docker ps --filter ancestor=d0e008c6cf02
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
82a598284012 ubuntu:24.04 "top" 3 minutes ago Up 3 minutes sleepy_bose
```
#### Create time
##### before
The `before` filter shows only containers created before the container with
a given ID or name. For example, having these containers created:
```console
$ 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:
```console
$ 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 a given
ID or name. For example, with the same containers as in `before` filter:
```console
$ 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:
```console
$ 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
```
#### 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`.
```console
$ 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:
```console
$ docker network inspect --format "{{.ID}}" net1
8c0b4110ae930dbe26b258de9bc34a03f98056ed6f27f991d32919bfe401d7c5
$ docker ps --filter network=8c0b4110ae930dbe26b258de9bc34a03f98056ed6f27f991d32919bfe401d7c5
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
9d4893ed80fe ubuntu "top" 10 minutes ago Up 10 minutes test1
```
#### publish and expose
The `publish` and `expose` filters show only containers that have published or exposed port with a given port
number, port range, and/or protocol. The default protocol is `tcp` when not specified.
The following filter matches all containers that have published port of 80:
```console
$ docker run -d --publish=80 busybox top
$ docker run -d --expose=8080 busybox top
$ docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
9833437217a5 busybox "top" 5 seconds ago Up 4 seconds 8080/tcp dreamy_mccarthy
fc7e477723b7 busybox "top" 50 seconds ago Up 50 seconds 0.0.0.0:32768->80/tcp admiring_roentgen
$ docker ps --filter publish=80
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
fc7e477723b7 busybox "top" About a minute ago Up About a minute 0.0.0.0:32768->80/tcp admiring_roentgen
```
The following filter matches all containers that have exposed TCP port in the range of `8000-8080`:
```console
$ docker ps --filter expose=8000-8080/tcp
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
9833437217a5 busybox "top" 21 seconds ago Up 19 seconds 8080/tcp dreamy_mccarthy
```
The following filter matches all containers that have exposed UDP port `80`:
```console
$ docker ps --filter publish=80/udp
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
```
### Format the output (--format)
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. |
| `.State` | Container status (for example; "created", "running", "exited"). |
| `.Status` | Container status with details about duration and health-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"}}'` |
| `.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:
```console
$ 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:
```console
$ 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
```
To list all running containers in JSON format, use the `json` directive:
```console
$ docker ps --format json
{"Command":"\"/docker-entrypoint.…\"","CreatedAt":"2021-03-10 00:15:05 +0100 CET","ID":"a762a2b37a1d","Image":"nginx","Labels":"maintainer=NGINX Docker Maintainers \u003cdocker-maint@nginx.com\u003e","LocalVolumes":"0","Mounts":"","Names":"boring_keldysh","Networks":"bridge","Ports":"80/tcp","RunningFor":"4 seconds ago","Size":"0B","State":"running","Status":"Up 3 seconds"}
```
