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!
