## NAME
|
|
podman\-ps - Print out information about containers
|
|
|
|
## SYNOPSIS
|
|
**podman ps** [*options*]
|
|
|
|
**podman container ps** [*options*]
|
|
|
|
**podman container list** [*options*]
|
|
|
|
**podman container ls** [*options*]
|
|
|
|
## DESCRIPTION
|
|
**podman ps** lists the running containers on the system. Use the **--all** flag to view
|
|
all the containers information. By default it lists:
|
|
|
|
* container id
|
|
* the name of the image the container is using
|
|
* the COMMAND the container is executing
|
|
* the time the container was created
|
|
* the status of the container
|
|
* port mappings the container is using
|
|
* alternative names for the container
|
|
|
|
## OPTIONS
|
|
|
|
#### **--all**, **-a**
|
|
|
|
Show all the containers created by Podman, default is only running containers.
|
|
|
|
Note: Podman shares containers storage with other tools such as Buildah and CRI-O. In some cases these `external` containers might also exist in the same storage. Use the `--external` option to see these external containers. External containers show the 'storage' status.
|
|
|
|
#### **--external**
|
|
|
|
Display external containers that are not controlled by Podman but are stored in containers storage. These external containers are generally created via other container technology such as Buildah or CRI-O and may depend on the same container images that Podman is also using. External containers are denoted with either a 'buildah' or 'storage' in the COMMAND and STATUS column of the ps output.
|
|
|
|
#### **--filter**, **-f**
|
|
|
|
Filter what containers are shown in the output.
|
|
Multiple filters can be given with multiple uses of the --filter flag.
|
|
Filters with the same key work inclusive with the only exception being
|
|
`label` which is exclusive. Filters with different keys always work exclusive.
|
|
|
|
Valid filters are listed below:
|

#### **--namespace**, **--ns**
|
|

|
|
#### **--sync**
|
|
|
|
Force a sync of container state with the OCI runtime.
|
|
In some cases, a container's state in the runtime can become out of sync with Podman's state.
|
|
This updates Podman's state based on what the OCI runtime reports.
|
|
Forcibly syncing is much slower, but can resolve inconsistent state issues.
|
|
|
|
#### **--watch**, **-w**
|
|
|
|
Refresh the output with current containers on an interval in seconds.
|
