I'm trying to test embedded Lua script in an Istio resource as part of a Java integration test. Normally we deploy to live Kubernetes environments and test Istio manually which is very slow, especially catching regressions. I've noticed there is a K3S Testcontainers - just wondering if anyone has had success with spinning up a K3S test containers with Istio installed and testing e.g. a Lua script as part an Istio Envoy Filter?
