Upstream Kubelet packaged as a container image

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.

Kubelet also requires:

• ca-certificates - kubernetes/kubernetes#7755
• ceph-common - kubernetes/kubernetes#34416
• cifs-utils - kubernetes/kubernetes#34416
• e2fsprogs (mkfs.ext4) - kubernetes/kubernetes#52789
• xfsprogs - kubernetes/kubernetes#56937
• ethtool - kubernetes/kubernetes#18273
• glusterfs-client - kubernetes/kubernetes#32686
• jq - coreos/bugs#1706
• kmod (modprobe) - kubernetes/kubernetes#53642
• nfs-common - kubernetes/kubernetes#30320
• udev (udevadm)- kubernetes/kubernetes#61357

kubectl

kubectl (no dependencies) is also included for convenience (e.g. use pre-pulled Kubelet image to kubectl delete node on preemption).
