Are people still using Docker in dev? What container runtime is primarily replacing Docker in k8s?

k8s now supports a pluggable system (CRI) which allows any conformant container runtime to be used. The default is now containerd.

Are people still using Docker in dev?

Most people I know switched to Podman and Buildah.

What container runtime is primarily replacing Docker on k8s?

Typically cri-o or containerd depending on the k8s implementation.

I feel like this progress for the sake of progress.

Sounds to me it’s more like a legacy artifact, with codepaths which much be tested and maintained, and the decision was made to get rid of it.

It’s interesting as I always considered Kubernetes very enterprise-focused. I wonder what the impact will be in terms of adoption of the new kubernetes version.

Legacy artifact that has been in production around the world in thousands (if not millions) of nodes.

Docker's relatively heavy and a pain in the ass to operate. We've switched everything other than our K8s cluster and local Mac dev away from it and I won't be sad if it disappears from either.

Docker, the company, didn't play very nice with the open-source community (ignoring pull requests from certain people, designing docker around just swarm and ignoring other use-cases, etc), so the ecosystem moved on.
