  • There are many ways to setups full disk encryption on Linux, but the most common all involve LUKS. Providing a password at mount (during boot, for a root partition or perhaps later for a “data” volume) is a but more secure and more frequently done, but you can also use things like smart cards (like a Yubikey) or a keyfile (basically a file as the password rather than typed in) to decrypt.

    So, to actually answer your question, if you dont want to type passwords and are okay with the security implementations of storing the key with/near the system, putting a keyfile on removable storage that normally stays plugged in but can be removed to secure your disks is a common compromise. Here’s an approachable article about it.

  • Little clusters of nucs has become a really common way to run small Kubernetes clusters at home. I recently rebuilt mine (still using a bulky, power hungry box like you’re tossing) and have been very happy with it. Everything is really stable, containers that misbehave are automatically destroyed and replaced, and updates are breeze because everything lives in code/git.
