Kubelet

kubelet provides a container image packaging the upstream Kubernetes kubelet and dependencies, for use on container-optimized OS distributions. kubelet is a component of the Typhoon Kubernetes distribution.

Repositories

Typhoon publishes Kubelet container images to repositories (detailed policy).

• quay.io/poseidon/kubelet (official)
• docker.io/psdn/kubelet (fallback)

Two tag styles indicate the build strategy:

• Single and multi-arch images are published by Typhoon infrastructure (e.g. v1.20.5, v1.20.5-amd64, v1.20.5-arm64)
• Quay or Docker autobuilt images (e.g. build-SHA on Quay, release-TAG on Dockerhub)

Packages

The debian-iptables base provides conntrack, ebtables, ipset, kmod, and netbase.
