Kubernetes

Deploy a Kubernetes cluster with a single master using kubeadm.

This role is still in development, and is based on https://kubernetes.io/docs/setup/independent/create-cluster-kubeadm/

There are several other Ansible playbooks and roles for installing a simple Kubernetes cluster, but I couldn't get them to work.

To check whether the cluster has been successfully deployed try on a master node try:

kubectl --kubeconfig /etc/kubernetes/admin.conf get pods --all-namespaces
kubectl --kubeconfig /etc/kubernetes/admin.conf get nodes

Dependencies

This role requires the distribution Docker package (you must install it yourself). Using the upstream package is currently not supported.

Role Variables

Required:

• kubernetes_role: Either master or worker, currently only a single master is supported

Optional:

• kubernetes_token: The token for initialising/joining a cluster
• kubernetes_advertise_address: The address for connecting to the Kubernetes master
• kubernetes_install_docker: Whether to automatically install the distribution docker (Kubernetes will probably fail if you try to use the upstream package)
