Create a Kubernetes clusters. Tested on Ubuntu baremetal and AWS EC2.

• Ubuntu 18.04
• Docker

1. git clone https://github.com/mingfang/docker-kubernetes-master
2. cd docker-kubernetes-master
3. ./build
4. ./run

The Master is now running

Note: Tested on Ubuntu 18.04. Newer versions should work but not tested.

1. git clone https://github.com/mingfang/docker-kubernetes-node
2. cd docker-kubernetes-node
3. ./build
4. On the Master, run docker exec kmaster /bootstrap-tokens.sh to generate the keys needed.
5. On the Node, run the command printed by #4. Should look something like this

KUBELET_TOKEN=s.oKCwIqfs7LGbIHJv666K9oFV PROXY_TOKEN=s.4TkiUcFsscWufhHUOzPjKgxn ./run <master-host>

The Node is now running. Repeat for every host that runs the Nodes.

1. alias kubectl='docker exec kmaster kubectl' on the Master host
2. kubectl get nodes
3. You should see all the Nodes running
