your client and daemon API versions.

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 networks created before given timestamp
• label (label=<key>, label=<key>=<value>, label!=<key>, or label!=<key>=<value>) – only remove networks 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 networks with the specified labels. The other
format is the label!=... (label!=<key> or label!=<key>=<value>), which removes
networks without the specified labels.

The following removes networks created more than 5 minutes ago. Note that
system networks such as bridge, host, and none will never be pruned:

$ docker network ls
