k8s-ansible : Ansible utility to deploy alpha/release version Kubernetes clusters.

Deploying a stable Kubernetes cluster

Prerequisite: Add in the node Public IP + hostname entries under /etc/hosts file on the deployer. For eg.

[root@kubetest2-tf1 hack]#
[root@kubetest2-tf1 hack]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
1.2.3.4 <Nodename 1>
1.2.3.5 <Nodename 2>

Method 1: Update fields in both hosts.yml and extra-vars-k8s.json to deploy cluster

Modify the host entry in the examples/containerd-cluster/hosts.yml and modify extra_cert in examples/containerd-cluster/extra-vars-k8s.json

ansible-playbook -i examples/containerd-cluster/hosts.yml install-k8s.yml --extra-vars "@examples/containerd-cluster/extra-vars-k8s.json"

Method 2: Deploy using hack/k8s-installer.sh for alpha/release Kubernetes installation

The k8s-installer.sh utility under hack, provides an option to choose between the latest release or the alpha version of Kubernetes to be deployed on VMs from the hack directory.

Example usages:

./k8s-installer.sh -c X.X.X.X -w Y.Y.Y.Y -p <playbook to use> -a|-r -y

To deploy latest Alpha release of k8s:

./k8s-installer.sh -w X.X.X.X -c Y.Y.Y.Y -a -y

To deploy latest Stable release of k8s:

./k8s-installer.sh -w X.X.X.X -c Y.Y.Y.Y -r -y

To deploy latest Stable release of k8s for perf-tests:

./k8s-installer.sh -p install-k8s-perf.yml -w X.X.X.X -c Y.Y.Y.Y -r -y
