Hetzner Deployer

Github Action for rolling deployments using Hetzner Loadbalancers.

For a list of provided servers (VMs):

• Removes the server target from the loadbalancer (via Hetzner API)
  • Possibility to wait a specified time to handle the inflight requests
• Run commands on the server (via SSH)
  • Deploy your new application version
• Inserts back the server into the loadbalancer
• Proceeds to the next server
