Earlier quoted context omitted.
This is kind of reductive. You could ask the same for nomad, mesos, and lots of other things. It wasn't just swarm vs k8s
How is it reductive? I do ask the same question for all those other systems, or the meta-question: "How is it that the bloated monstrosity of Kubernetes somehow became the de-facto container orchestration tool?" Is this just sysadmins buying themselves job security?
Devs chose K8s, I think the evangelism phrase was “developer dopamine”. It felt like the Rails of DIY infra, where devs could inherit an opinioned pattern for doing n>1.
There’s still decades of resentment of devs being gated by IT.
