ansible-playbook helper/store_known_hosts.yml

HowTo

Add new machine

• Update DNS zonefile in files/coredns/zones/
• add A and AAAA records
• update serial (yyyymmddvv with vv being the version increment. E.g., 2020040101)
• Update DNS by ansible-playbook main.yml --tags dns
• Enter Hostname twice in inventory, below [all] and below the other role the machine should have, eg. [bbb]
• Confirm that you can ssh into the machine by its newly aquired dns name (this also adds the host key to your ~/.ssh/known_hosts)
• run ansible-playbook main.yml -l your.fresh.hostname.example (you may need --user root if you don't have an user yet, the base role creates one for you)
• ...?
• register your new bbb instance:
  • at the monitoring by running ansible-playbook main.yml --tags monitoring
  • at the loadbalancer by running ansible-playbook main.yml --tags config
• enable it manually in the loadbalancer
