docker container ls Description List containers Usage docker container ls [OPTIONS] Aliases

An alias is a short or memorable alternative for a longer command.

docker container list docker container ps docker ps

List containers

Option Default Description -a, --all Show all containers (default shows just running) -f, --filter Filter output based on conditions provided --format Format output using a custom template:
'table': Print output in table format with column headers (default)
'table TEMPLATE': Print output in table format using the given Go template
'json': Print in JSON format
'TEMPLATE': Print output using the given Go template.
Refer to https://docs.docker.com/go/formatting/ for more information about formatting output with templates -n, --last -1 Show n last created containers (includes all states) -l, --latest Show the latest created container (includes all states) --no-trunc Don't truncate output -q, --quiet Only display container IDs -s, --size Display total file sizes Do not truncate output (--no-trunc)

Running docker ps --no-trunc showing 2 linked containers.

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:

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:

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 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 <key> or <key>=<value> 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 <image-name>[:<tag>], <image id>, or <image@digest> 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 <port>[/<proto>] or <startport-endport>/[<proto>] 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.

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

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.

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

exited

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

Filter by exit signal

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

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:

To filter for paused containers:

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:

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

Match containers based on the ubuntu version 24.04 image:

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

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:

Filtering with before would give:

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:

volume

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

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.

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:

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:

The following filter matches all containers that have exposed TCP port in the range of 8000-8080:

The following filter matches all containers that have exposed UDP port 80:

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:

To list all running containers with their labels in a table format you can use:

To list all running containers in JSON format, use the json directive:
