Do in parallel the two sets of steps - first one deals with software and the second one with networking:

• Download appropriate Armbian version
• Flash to SD card using Etcher
• Put SD card in device, connect to internet and power
• Wait a bit, find device assigned IP (for example with arp-scan), connect with ssh and root:1234
• set a root password following prompts and remember it. Don't make account (ctrl+c when it asks)
• sudo armian-config > System > Install to eMMC > ext4 filesystem > wait 15 minutes... > accept power off > take SD card off > turn on
• sudo armiban-config > Personal > timezone to Sofia and hostame to magare#
• Make a magare#.otselo.eu entry in production
• Make an A DNS record for the new magare (magare#.otselo.eu)
• Add a crontab rule for root: curl -4 "https://magare#.otselo.eu:[email protected]/nic/update?hostname=magare#.otselo.eu", where pass is taken from DNS console
• Add a new entry to couchdb-cluster.yaml
• Configure tunneling (through router for example), make sure host is reachable on magare#.otselo.eu, ideally Demilitarized Host (all traffic forwarded to it), otherwise ports 22, 80, 443, 4369, 6984, 9100-9200
• ansible-playbook magareta.yaml -l "magare#.otselo.eu" --ask-vault-pass --ask-pass

Make sure user onmagareta has passwordless sudo access:

echo " ALL = (root) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/

ansible-playbook couchdb.yaml -e @couchdb_variables.yaml --ask-vault-pass

Where couchdb_variables.yaml is a YAML file in the current directory with admin_user, admin_password and cookie (ideally admin_password and cookie are encrypted with Ansible)

Intially do:

cd design-documents ./update-version-control.sh "" $BUCKET user_colon_password.txt update.js validate.js

Then to update the design documents, specify a revision as the first argument instead of ""

ansible-galaxy install ipr-cnrs.nftables ansible-galaxy install geerlingguy.certbot

Each magare runs HAProxy on ports [80,443] and CouchDB on a random port. Each magare's HAProxy is configured to distribute traffic directly to the CouchDBs. That way if one magare fails, another can take over magare.otselo.eu (TODO).
