This is a really bad take. I’m all for OSS, but that doesn’t mean that there isn’t value with things like Docker.
Yes, developers know less about infra. I’d argue that can be a good thing. I don’t need my devs to understand VLANs, the nuances of DNS, or any of that. I need them to code, and code well. That’s why we have devops/infra people. If my devs to know it? Awesome, but docker and containerization allows them to focus on code and let my ops teams figure out how they want to put it in production.
As for OSS - sure, someone can come along and make an OSS solution. Until then - I don’t really care. Same thing with cloud providers. It’s all well and good to have opinions about OSS, but when it comes to companies being able to push code quickly and scalably, then yeah I’m hiring the ops team who knows kubernetes and containerization vs someone who’s going to spend weeks trying to spin up bare iron machines.
