For that matter, pushing for SRE roles that manage orchestrating the K8s environment and as a developer you can focus on a local docker-compose, and spend more time in testing (unit and integration). The Developer is responsible for Dockerfile, and the CI/CD build and test portions of the process.

Considering the level of options from Kubernetes, heml, istio, etc can get complex, the developer can focus on the boundary requirements... expected environment variables and peer systems/services.
