Virtual Kubelet
This package provides an impelementation of a virtual cluster node using virtual-kubelet.
The implementation is based on several projects, including:
Overview
This project creates a node that registers itself in the virtual cluster. When workloads are scheduled to this node, it simply creates/updates the workload on the host cluster.
Usage
Build/Push the image using (from the root of rancher/k3k):
make build
docker buildx build -f package/Dockerfile . -t $REPO/$IMAGE:$TAG
When running, it is recommended to deploy a k3k cluster with 1 server (with --disable-agent as a server arg) and no agents (so that the workloads can only be scheduled on the virtual node/host cluster).
After the image is built, it should be deployed with the following ENV vars set:
CLUSTER_NAMEshould be the name of the cluster.CLUSTER_NAMESPACEshould be the namespace the cluster is running in.HOST_KUBECONFIGshould be the path on the local filesystem (in container) to a kubeconfig for the host cluster (likely stored in a secret/mounted as a volume).VIRT_KUBECONFIGshould be the path on the local filesystem (in container) to a kubeconfig for the virtual cluster (likely stored in a secret/mounted as a volume).VIRT_POD_IPshould be the IP that the container is accessible from.
This project is still under development and there are many features yet to be implemented, but it can run a basic nginx pod.
