How can I load multiple tar images using nerdctl? (containerd)

Purge Kubernetes Image Cache on containerd runtime with daemonSet

Unable to retrieve data from Docker-managed containerd by using containerd-based CLI directly

QUESTION

How can I load multiple tar images using nerdctl? (containerd)

Asked 2022-Feb-01 at 07:59

There are around 10 container image files on the current directory, and I want to load them to my Kubernetes cluster that is using containerd as CRI.

Your actual ls command piped to xargs is seen as a single argument where file names are separated by null bytes (shortly said... see for example this article for a better in-depth analyze). If your version of xargs supports it, you can use the -0 option to take this into account:

QUESTION

Purge Kubernetes Image Cache on containerd runtime with daemonSet

Asked 2021-Apr-06 at 02:17

I am trying to purge images from the local kubernetes cache on a set cadence. Before you could setup some volumeMounts on a daemonSet and talk to the docker runtime directly.

The latest runtime is based on containerd but I can't seem to connect using the containerd.sock - when I run ctr image ls or nerdctl it shows as nothing running or images on the node. It also returns no errors.

Is there a different method for manually purging from the containerd runtime running on a daemonSet?

Answered in comments, most containerd commands are built for the Docker integration which uses the default containerd namespace (note, nothing to do with Linux namespaces, this is administrative namespacing inside containerd). Most commands have an option to set the ns being used but crictl is already set up for the CRI namespace that Kubernetes uses (because it's also a CRI client).

Here's what I want to accomplish:

Run Docker and be able to manage its images/containers from containerd's API. This is purely an educational exercise.

Got an answer from Docker maintainer Sebastiaan van Stijn:

dockerd uses the runtime components of containerd, but not (yet?) the image store and snapshotters, which is why you don't see the images, only containers
