NAME
netplan-try - try a configuration, optionally rolling it back
SYNOPSIS
netplan [--debug] try -h | --help netplan [--debug] try [--config-file CONFIG_FILE] [--timeout TIMEOUT]
DESCRIPTION
netplan try takes a netplan(5) configuration, applies it, and automatically rolls it back if the user does not confirm the configuration within a time limit. This may be especially useful on remote systems, to prevent an administrator being permanently locked out of systems in the case of a network configuration error.
OPTIONS
-h, --help Print basic help. --debug Print debugging output during the process. --config-file CONFIG_FILE In addition to the usual configuration, apply CONFIG_FILE. It must be a YAML file in the netplan(5) format. --timeout TIMEOUT Wait for TIMEOUT seconds before reverting. Defaults to 120 seconds. Note that some network configurations (such as STP) may take over a minute to settle.
KNOWN ISSUES
netplan try uses similar procedures to netplan apply, so some of the same caveats apply around virtual devices. There are also some known bugs: if netplan try times out or is cancelled, make sure to verify if the network configuration has in fact been reverted. As with netplan apply, a reboot should fix any issues. However, be sure to verify that the config on disk is in the state you expect before rebooting!
