This is an enhancement for the podman system prune feature. In this issue, it is mentioned that 'network prune' should be wired into 'podman system prune' https://github.com/containers/podman/issues/8673 Therefore, I add the function to remove unused networks.

## NAME
|
||
podman\-system\-prune - Remove all unused pods, containers, images, networks, and volume data
|
||
|
||
## SYNOPSIS
|
||
**podman system prune** [*options*]
|
||
|
||
## DESCRIPTION
|
||
**podman system prune** removes all unused containers (both dangling and unreferenced), pods, networks, and optionally, volumes from local storage.
|
||
|
||
With the **--all** option, you can delete all unused images. Unused images are dangling images as well as any image that does not have any containers based on it.
|
||
|
||
By default, volumes are not removed to prevent important data from being deleted if there is currently no container using the volume. Use the **--volumes** flag when running the command to prune volumes as well.
|
||
|
||
## OPTIONS
|
||
#### **--all**, **-a**
|
||
|
||
Recursively remove all unused pods, containers, images, networks, and volume data. (Maximum 50 iterations.)
|
||
|
||
#### **--filter**=*filters*
|
||
|
||
Provide filter values.
|
||
|
||
The *filters* argument format is of `key=value`. If there is more than one *filter*, then pass multiple OPTIONS: **--filter** *foo=bar* **--filter** *bif=baz*.
|
||
|
||
Supported filters:
|
||
|
||
| Filter | Description |
|
||
| :----------------: | --------------------------------------------------------------------------- |
|
||
| *label* | Only remove containers and images, with (or without, in the case of label!=[...] is used) the specified labels. |
|
||
| *until* | Only remove containers and images created before given timestamp. |
|
||
|
||
The `label` *filter* accepts two formats. One is the `label`=*key* or `label`=*key*=*value*, which removes containers and images with the specified labels. The other format is the `label!`=*key* or `label!`=*key*=*value*, which removes containers and images without the specified labels.
|
||
|
||
The `until` *filter* can be Unix timestamps, date formatted timestamps, or Go duration strings (e.g. 10m, 1h30m) computed relative to the machine’s time.
|
||
|
||
#### **--force**, **-f**
|
||
|
||
Do not prompt for confirmation
|
||
|
||
#### **--help**, **-h**
|
||
|
||
Print usage statement
|
||
|
||
#### **--volumes**
|
||
|
||
Prune volumes currently unused by any container
