I never moved to containers and seeing the churn the community has went through with all of this complicated container tooling, I'm happy orchestrating small-scale systems with supervisord and saltstack-like chatops deployments - it's just stupid simple by comparison and provides parity between dev and prod environments that's nice.
What churn? For 95% of users, the way to use containers hasn't changed in the past decade. It's just a combination of docker CLI, maybe some docker compose for local testing and then pushing that image somewhere.
True perhaps from a certain perspective, but k8s and the other orchestration technologies, etc. Also dev workflows in containers seem broken and hard - I think it offers a poor experience generally.
Too many gaps around image management. It seems like an unfinished feature that wasn't completely thought out IMO. Podman is what systemd-nspawns OCI interface should've become.
