Provide filter values.
The --filter flag format is of “key=value”. If there is more than one filter, then pass multiple flags (e.g., --filter "foo=bar" --filter "bif=baz")
Supported filters:
- `until` (_timestamp_) - only remove containers and images created before given timestamp
- `label` (label=_key_, label=_key=value_, label!=_key_, or label!=_key=value_) - only remove containers and images, 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 machine’s time.
The label filter accepts two formats. One is the label=... (label=_key_ or label=_key=value_), which removes containers with the specified labels. The other format is the label!=... (label!=_key_ or label!=_key=value_), which removes containers without the specified labels.
#### **--force**, **-f**
Do not provide an interactive prompt for container removal.
