No testing environment in my home lab so far.
But on the other hand, no planned builds either. Just fiddling around til it works.
I am currently planning for new hardware, and then doing it all with build scripts there, as fully automated as possible. The whole setup, from scratch. But for that I need to do some learning first.
So the new hardware is going to be it’s own test environment for a good while, until it turns into production.
No. Never would I self-host a search engine.
The crawler would eat up so much more ressources than I am ever willing to spend.
