  • Did some reading, yea you’re right.

    So many of the containers run in K8s are built with docker, but the containers themselves aren’t docker.

    I think many people (like I used to 10min ago) think that docker = some-kind-of-container.

    Best plain-English version:

    Kubernetes is an orchestrator:

    • Docker Engine and Podman are container engines.
    • Kubernetes used to support Docker Engine via dockershim, but that support was removed in v1.24.
    • Kubernetes now talks to runtimes like containerd or CRI-O.
    • You can still build images with Docker and run them on Kubernetes, but Kubernetes is not “using Docker under the hood” in the old sense anymore.
