Own-Kubernetes

Hello, I had my work on trying to write on my own Kubernetes like program It consists of kubelet, kube-proxy and kube-api

demo:

Prerequsuite:

• Golang 1.22+ installed
• Makefile installed
• Docker installed (for building images)
• Qemu installed
• Need to have in the repository VM image for the node VM (I have used debian image) located in ./vms folder - in the image need to be installed containerd
• Need to enable libvirtd
• Need to create ssh keys in and place them in ./vms/.ssh/

How To run?

  make

• This will build the images and upload them to the regisrty
• Build kubelet binary and kubectl like binary
• Start the node
• SSH to it

To start the kubelet in the node:

 sudo ./kubelet --kubernetes-api-endpoint 'http://localhost:8080'

To interact with the kube-api (in local machine):

export KUBE_API_ENDPOINT=http://${NODE_IP}:8080
./bin/own-kubectl get pods

Supported functionality:

• Create a Namespace
• Create and delete pods using YAML
• Create and delete services (clusterIP and NodePort) associated with those pods (endpoints are created under the hood)
