NAME

       netplan-generate - generate backend configuration from netplan YAML files

SYNOPSIS

       netplan [–debug] generate -h | –help

       netplan [–debug] generate [–root-dir ROOT_DIR] [–mapping MAPPING]

DESCRIPTION

       netplan generate converts netplan YAML into configuration files understood by the backends
       (systemd-networkd(8)  or  NetworkManager(8)).    It   does   not   apply   the   generated
       configuration.

       You  will  not  normally  need to run this directly as it is run by netplan apply, netplan
       try, or at boot.

       For details of the configuration file format, see netplan(5).

OPTIONS

       -h, –help
              Print basic help.

       –debug Print debugging output during the process.

       –root-dir ROOT_DIR
              Instead      of      looking      in      /{lib,etc,run}/netplan,      look      in
              /ROOT_DIR/{lib,etc,run}/netplan

       –mapping MAPPING
              Instead  of  generating  output files, parse the configuration files and print some
              internal information about the device specified in MAPPING.

HANDLING MULTIPLE FILES

       There are 3 locations that netplan generate considers:

       · /lib/netplan/*.yaml

       · /etc/netplan/*.yaml

       · /run/netplan/*.yaml

       If there are multiple files with exactly the same name, then only one  will  be  read.   A
       file  in  /run/netplan  will  shadow  -  completely replace - a file with the same name in
       /etc/netplan.  A file in /etc/netplan will itself shadow a file in /lib/netplan.

       Or in other words, /run/netplan is top  priority,  then  /etc/netplan,  with  /lib/netplan
       having the lowest priority.

       If there are files with different names, then they are considered in lexicographical order
       - regardless of the directory they are in.  Later files add to or override earlier  files.
       For example, /run/netplan/10-foo.yaml would be updated by /lib/netplan/20-abc.yaml.

       If you have two files with the same key/setting, the following rules apply:

       · If  the  values are YAML boolean or scalar values (numbers and strings) the old value is
         overwritten by the new value.

       · If the values are sequences, the  sequences  are  concatenated  -  the  new  values  are
         appended to the old list.

       · If  the  values  are mappings, netplan will examine the elements of the mappings in turn
         using these rules.
