hetzner failover switch

This is a simple monitoring script which can check periodically a postgreSQL connection on a postgreSQL cluster hosted on hetzner with an failover ip.

configuration

• copy config.example.yaml to config.yaml and set the configuration
• add an ssh key to ssh/id_rsa which can access the server to create a trigger file
• (optional) add ssl certificates to ssl/client.crt, ssl/client.key and ssl/root.crt if your postgreSQL cluster support ssl connection
• run ruby check.rb via cron
