Server

Essential server setup tasks, like sshd config, ddns cronjobs (+ mail output), etc used by Jannik Beyerstedt.

Requirements

none

Role Variables

There are several variables, that should be set per host (e.g. in the inventory).

Some of the tasks listed below, will not run, if the corresponding variables are not set. Therefore you can use the same playbook for multiple servers and activate the needed features with host variables.

Borgbakup

If you want to configure borgbackup backups, these variables need to be set:

borgbackup_host: Hostname used by the borgbackup script
borgbackup_sub: Sub-Account ID used by the borgbackup script

Attention: You still need to setup the borgbackup repository manually.

Telegraf

Telegraf is configured with basic host telemetry by default. You can add more features, if you like:

telegraf_docker: Set to true, if docker telemetry should be collected
telegraf_snmp_fra80: Set to true, if SNMP telemetry of the fra80 network should be collected

Dependencies

none
