Kubernetes Is Moving on from Dockershim: Commitments and Next Steps

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.

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.

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.
