Deploy Kubernetes Master With The Calico Network:

• Run on a Ubuntu 22.04 hosts or VM that you want dedicated as Master

./container_toolkit.sh --master-calico

• Once done, check your pods:

kubectl get pods --all-namespaces

NAMESPACE     NAME                                      READY   STATUS    RESTARTS   AGE
kube-system   calico-kube-controllers-7b9dcdcc5-dsm52   1/1     Running   0          74s
kube-system   calico-node-q9g9f                         1/1     Running   0          75s
kube-system   coredns-5644d7b6d9-k5z7x                  1/1     Running   0          75s
kube-system   coredns-5644d7b6d9-q2464                  1/1     Running   0          75s

kube-system   kube-apiserver-container-host             1/1     Running   0          23s
kube-system   kube-controller-manager-container-host    1/1     Running   0          17s
kube-system   kube-proxy-z4fqq                          1/1     Running   0          75s
kube-system   kube-scheduler-container-host             1/1     Running   0          19s

Deploy Kubernetes Workers:

• Run on a Ubunutu 22.04 hosts or VM that you want dedicated as a Worker

./container_toolkit.sh --worker-node

• Obtain your secret from master and add to each worker node.
• You can verify all is working by running on Master:

kubectl get nodes
NAME             STATUS   ROLES    AGE     VERSION
container-host   Ready    master   5m57s   v1.16.2
k8-node1         Ready    <none>   2m58s   v1.16.2
k8-node2         Ready    <none>   2m55s   v1.16.2
k8-node3         Ready    <none>   2m55s   v1.16.2

Side note

We have found Ubuntu 22.04 doesn't always disable swap after a reboot. You most likely will need to ssh into the nodes and disable swap, then restart kubernetes to get the services working:

sudo /sbin/swapoff -av
sudo systemctl restart kubelet.service

Install Dockerfile

docker build -t container_toolkit .
docker run --rm -it container_toolkit /opt/container_toolkit/Ubuntu/container_toolkit.sh -h
