Devops:

One word of caution. The future really will be having a docker file and finding a place to run code (docker swarm, ecs, etc). When you commit code it will be ran through a ci system (unit tested, staged) then updated.

The salts, puppets, chefs, Vaults, running your own Kubernetes (wtf), VMs, Nagios, sendmails, vpcs and all this other drama will be latin in a few years.

The future will be running the code on your macbook (with container of choice), then commiting. The end.

Sorry but Kubernetes is production ready. Swarm is everything but. If you struggle with K8s, give Deis Workflow a try.

ECS is proprietary, learning how Kubernetes works gives you flexibility to move between cloud providers. GKE is a beast.

This could be true, from a developer's perspective. But the OP was in the spirit of expanding one's knowledge and understanding. But even if a single-interface, fully-managed container orchestration service is available to all, the value of understanding how the underlying systems actually function will not cease to exist. Anyone building moderately complex systems will still want to know about OS, networks, storage systems, access control, and all the rest, because those areas of expertise are applicable and useful across the stack.

This is not particularly helpful advice. All of these things are worth learning and they are all still in widespread use and aren't going to disappear overnight. On top of that it's not like docker is some magic wand that magically makes DevOps happen. If that's the future it's not here yet and doesn't answer the OP's question.

Exactly. So I would start studying this. Like container security, how ci works with containers, how ecs works. Instead of terrible advice like 'learn how puppet works'. Further it is helpful advice. If someone asked me how they can get involved in action script coding I would warn them too.
