  • Define production lol. I’ve used it for a CI cluster for a few years. Have had to recreate it a few times due to database corruption (despite using etcd across 3 nodes).

    Honestly Rancher management is more of a pain than manually managing via ansible or something. And swapping to CRI-O backend instead of containerd js a huge pain for Rancher/RKE2, but pretty easy with k3s.



  • End-to-end tests are basically non-deterministic state machines. Flakiness can come from any point in the test: bad tests, bad state management, conflicting tests, network hiccups, etc.

    Your goal is to reduce every single point of that flakiness. Just make sure you keep track of it. Sometimes flakiness in tests is really pointing at flakiness in the product itself.

    Some things that can help reduce that flakiness:

    • Dedicated network
    • No external dependencies
    • Polling instead of static waits/sleeps
