Whip up Foreman in a bunch of Docker containers (one for the front-end, another one for the smart proxy, plus PostgreSQL and Træfik). Then, use that and Foreman + foreman_ansible that to spray some Kubespray everywhere.
Inventory of clusters you want to Kubespray is in managed-inventory.yml. Once you have made the desired changes,
./foresible
Then log in to Foreman, install the nodes (see detailed procedure below), and finally look for the Kubespray button under Configure → Host Groups.
Precious state: none (besides whatever you put onto the generated Kubernetei of course)
Semi-precious state:
- ssh key that Foreman puts into nodes'
/root/.sshto retain access — If you lose it you will either have to reinstall the node, or put the new one back in by hand - front-end certificate — If you lose it, your browser will complain. Again
Foreman is configured to install (or reinstall) all the cluster nodes with Ubuntu 20.04.
