Passwords

You need to create the file vault_password and put the ansible vault password in there.

SSH Host Keys

Get all SSH host keys and store in local .ssh/known_hosts file by executing following skript

ansible-playbook helper/store_known_hosts.yml

Run

ansible-playbook main.yml

HowTo

Add new machine

  • Update DNS zones
  • 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

Things to tell your Network Admin

  • Proxy exeptions for IPv4 adress of turnserver
