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:
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
$ docker system prune -a --volumes
|
|||
|

### Filtering
|
|||
|
|
|
|||
|
|
The filtering flag (`--filter`) format is of "key=value". If there is more
|
|||
|
|
than one filter, then pass multiple flags (e.g., `--filter "foo=bar" --filter "bif=baz"`)
|
|||
|
|
|
|||
|
|
The currently supported filters are:
|
|||
|
|
|
|||
|
|
* until (`<timestamp>`) - only remove containers, images, and networks created before given timestamp
|
|||
|
|
* label (`label=<key>`, `label=<key>=<value>`, `label!=<key>`, or `label!=<key>=<value>`) - only remove containers, images, networks, and volumes with (or without, in case `label!=...` is used) 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 daemon machine’s time. Supported formats for date
|
|||
|
|
formatted time stamps include RFC3339Nano, RFC3339, `2006-01-02T15:04:05`,
|
|||
|
|
`2006-01-02T15:04:05.999999999`, `2006-01-02Z07:00`, and `2006-01-02`. The local
|
|||
|
|
timezone on the daemon will be used if you do not provide either a `Z` or a
|
|||
|
|
`+-00:00` timezone offset at the end of the timestamp. When providing Unix
|
|||
|
|
timestamps enter seconds[.nanoseconds], where seconds is the number of seconds
|
|||
|
|
that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap
|
|||
|
|
seconds (aka Unix epoch or Unix time), and the optional .nanoseconds field is a
|
|||
|
|
fraction of a second no more than nine digits long.
|
|||
|
|
|
|||
|
|
The `label` filter accepts two formats. One is the `label=...` (`label=<key>` or `label=<key>=<value>`),
|
|||
|
|
which removes containers, images, networks, and volumes with the specified labels. The other
|
|||
|
|
format is the `label!=...` (`label!=<key>` or `label!=<key>=<value>`), which removes
|
|||
|
|
containers, images, networks, and volumes without the specified labels.
