There are a couple of things here. 1) Right now everyone is afraid that Docker will emulate VMware, and crowd them out of the container space, much like VMware killed most of their competitors. 2) To this end, I have heard that Google and Redhat have massive marketing budgets, and that the marching orders have been over and over - don't say docker, say k8s. 3) The real battle is where the money is - large scale distributed systems. Companies want to freeze docker out, because Docker controls the lowest point of access - the container runtime itself. 4) hence google is trying to push "docker compatible" ideas that are just the OCI standard - nothing to do with Docker itself.

AWS doesn't want to support Swarm, because it gives people portability off of their cloud. Google doesn't want to support swarm, because K8s is a trojan for Google Cloud. No one else wants to support swarm because it competes with their products.

That said, what's happening right now, if we are not careful, will fragment the container ecosystem, and it make it impossible for single containers to target multiple runtimes.

Docker is the only one who can deliver a universal set of functionality that is leveraged by all. From a technology point of view, Docker is going in the right direction. We got burned with Redhat in Openshift 1 & 2 land, and that's left us with a point of view that the only thing we can depend on is a container runtime itself, and 12fa applications.

K8s does not really work that way. It's huge and it's heavy, and it expects every app to be written it's way.

The technical direction here for Docker is good. But the implementation and early release is ridiculous. I was impressed by the first RC release, and then terrified that they released a RC as production.
