The first problem I didn't want to deal with manually was configuring the ssh on the RPis. In the previous process, I had one playbook to configure the ssh and user on Raspberian and another to configure everything else. This time, though, the node will boot with password login disabled and with my public keys automatically added to the host. To achieve this, I used Raspberian Firstboot with a custom script to set up the ssh configuration and hostname.

My first approach to keeping secrets versioned was using Sealed Secrets. However, I gave up on the sealed secrets because I rebuilt the cluster frequently and always lost the encryption keys since I didn't care to make backups. I found it a lot easier to keep an encrypted secrets.yaml file in the repository. Every time I spin up a new cluster in this workflow, I have to decrypt the file and apply it to the new cluster. Although it is encrypted, I don't recommend keeping the file in a public Github repository. I'm doing this to avoid losing the secrets while I work out a better flow for personal projects.
