You only have to worry about licences if you use Docker DESKTOP. Why not use RANCHER Desktop?

I have been using it by years. Tested it in Win11 and Linux Mint. I can have even a local kubernetes.

Low-quality UX (e.g. you have to switch tabs and switch back if you ever want to see the current state of your containers, because it loads it once when you open the tab and never updates, and doesn't even give you a button to refresh it), lack of documentation, behavioural changes that happen silently (e.g. it autoupdates which changes the VM hostname, so the thing that was working yesterday doesn't work today and you have no idea why) and general flakiness.

I concur. My company is using Rancher Desktop on Windows machines. No problems. As long as you use don't care about GUI, and just use CLI dommands ("docker" , "docker compose" ).

Why not use Docker Engine/CE on Linux so you don't have to run a VM?

I got a hard time trying to integrate Spring Security 3.1 and Keycloak. All examples are based on @Deprecated connectors. Even in Spring Security there are a lot of huge changes ongoing.

I had worked +/- 5 months ago a lot with nodered. One thing I miss is some kind of benchmark performance for huge projects. Is something new in docs regarding this? This tool is really great.

I agree! what kind of project were you working on that you consider a 'huge project' genuinely curious to learn how other people are applying this to use-cases beyond home automation!
