Awesome post! One question though: why is everyone focusing on Docker so much when Kubernetes, which arguably most people use nowadays, uses cri-o, rkt or similar Docker replacements most of the time? Do ker Swarm is pretty much dead now. I'd argue that knowing how Helm charts and k8s YAML works is much more important than writing Dockerfiles, and CI/CD is handled by GitLab anyways, I guess ...
Mostly because Docker is focused on dev workflows, whereas K8S is focused on production workflow. IMO, dev use docker containers to build and test app, then, ops push this in production using K8S.
Late comment to an old article, but I'd just like to point something out.
DevOps != Docker, k8s, and so forth.
There's always this immediate jump when talking about DevOps to talk about containers, but containers don't answer everything and are mostly a different solution for the "infrastructure" side of DevOps. There's so much more to it, but the focus is always containers.
If I'm going to hire for a DevOps role, I'm going to ask questions about DevOps philosophy, lean principles, etc. The tech part is not the hard part of DevOps. Docker / k8s can be taught as long as someone is in the mindset of DevOps is what I care about.
I'm going to blow some minds here but you can do DevOps and never touch containers. 😲😲😲
