Re: [bareos-users] Working with variables in the Python plugin

[Sebastian Sura]

Hi Stefan,

Plugin Options are passed verbatim to the plugin.  It would be up to the plugin how to handle these variables.
As far as I am aware, almost no plugin tries to do such expansions in their options.

There is one ugly way to do it however:
Writing `Plugin = "\\|command"` makes it so that the client executes the command and parses its standard output as a list of plugin directives.
So you should be able to do `Plugin = "\\|echo python:module_name..."` etc. This probably needs to be all in one line however.

See https://docs.bareos.org/Configuration/Director.html#config-Dir_Fileset_Include_File here for infos (Its only documented for `File`, but it should also work for `Plugin`).

Kind Regards
Sebastian Sura

Hi everyone,

i have a question.

Can I work with variables in Python plugins?

For example

...
root@bareos:~# cat /etc/bareos/bareos-dir.d/fileset/plugin-postgresql.conf
FileSet {
    Name = "plugin-postgresql"
    Include  {
        Options {
            compression=LZ4
            signature = XXH128
        }
        Plugin = "python"
                 ":module_name=bareos-fd-postgresql"
                 ":db_host=$HOSTNAME --fqdn"
                 ":db_user=########"
                 ":db_password=###########"
                 ":wal_archive_dir=/media/backups/dsme01.intern.example.com/postgresql/wal_archives/"
    }
}
...

The entry "db_host=$HOSTNAME --fqdn" does not work
