I’m not sure it helps or hinders lock in, compared to the alternative of managing some Linux VMs. If you have a bunch of Linux VMs and run free software you aren’t locked in. Kubernetes might make it easier to manage and administer things but that is a controversial topic, with some people saying it adds complexity and requires even more refined sysadmin skills than running stuff straight on the machines. For a personal project I’m using a cheap VMs and just the Debian package manager to install what I need, plus a list of steps I could turn into a shell script if required.
