I am using a I7 machine with 64G of ram and a 600G disk and I connect to my openwrt where I use dnsmask to simulate A records on my box machine I use the xen server XCP-NG what is a greate aquesition and it brings XOA Great job! or KVM and use vagrant to deployment you can clone my repo Orpere and kubespray inside what will help with the kubernetes build.
1 - create a themplate in xen with your election distro "I have add ubuntu18.04 and centos7" and don't forget to add your public key to the instances and enable sudo to your user. I use NOPASSWD
2 - run kubespray against your instances and don't forget to add the option --user and --private-key to your ansible-playbook command
ansible-playbook -i inventory/mycluster/hosts.yml --user=<YOUR USER> --become --become-user=root cluster.yml --private-key=<YOUR KEY>NOTE: this will take long time please have a coffe :)
3 - get your kubectl working it will help to manage the cluster form your network
3.1 - Copy from the kubespray host the file on /etc/kubernetes/admin.conf to your local ~/.kube/config 3.2 - kubectl cluster-info should return:
Kubernetes master is running at https://<api_ip>:6443
coredns is running at https://<api_ip>:6443/api/v1/namespaces/kube-system/services/coredns:dns/proxy
kubernetes-dashboard is running at https://<api_ip>:6443/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy3.3 - kubectl config current-context (for check what cluster is your config ) should return something as: [email protected]
4 - get metallb working
kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.9.5/manifests/namespace.yaml
kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.9.5/manifests/metallb.yaml
# On first install only
kubectl create secret generic -n metallb-system memberlist --from-literal=secretkey="$(openssl rand -base64 128)"
kubectl apply -f k8s-cluster-manifests/metallb-map.yaml5 - install traefik
helm init --wait
kubectl create serviceaccount --namespace kube-system tiller
kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
kubectl patch deploy --namespace kube-system tiller-deploy -p '{"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}'
helm install stable/traefik --name traefik --set dashboard.enabled=true,serviceType=NodePort,dashboard.domain=dashboard.traefik,rbac.enabled=true --namespace kube-system
#traefik dashboard with password
note: first need to remove the previous deployment
htpasswd -nb traefik password
helm install stable/traefik --name traefik --set dashboard.enabled=true,serviceType=LoadBalancer,dashboard.domain=traefik.lan,rbac.enabled=true,dashboard.auth.basic.traefik='$apr1$npha/qF1$VD51O1swfgGWmuiaDfdZA0' --namespace kube-system
Note: check the service type and password6 - create a dashboard user admin
kubectl apply -f k8s-cluster-manifests/cluster-admin.yaml
kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | (grep admin-user || echo "$_") | awk '{print $1}') | grep token: | awk '{print $2}'
