QUESTION
I want to prune docker images, I wrote a small Docker image using node-docker-api
and I was able to test it locally with success.
As I've deployed the DaemonSet
to Kubernetes, the pod fails to access the Docker socket:
ANSWER
Answered 2019-Oct-30 at 10:34There is no guarantee that your kubernetes cluster is actually using docker as container engine. As there are many alternatives like cri-o and kata containers your application/deployment should make no assumptions about the underlying container engine.
Kubernetes takes care about cleaning up unused container images automatically. See documentation on how to configure it, if you run the cluster yourself: https://kubernetes.io/docs/concepts/cluster-administration/kubelet-garbage-collection/
Aside from that it looks like you have a simple permission problem with the socket: Make sure your application in the cleanup container runs as root or has appropriate user to access the socket.
