Ansible script to provision kubernetes cluster with contiv network CNI, also deploys sample applications with micro segmentation and istio service mesh.

Basic Install of Kubernetes and Contiv Networking

standalone kubeadm deployment

Orignal code credit goes to https://github.com/ben-st/ansible-kubeadm. I used it as a base and changed the CNI to Contiv (by Cisco).

• Requires Ansible 2.4 or newer
• Expects 3 ubuntu nodes (at least 16.04)
• Expects passwordless sudo

These playbooks deploy a very basic installation of kubeadm. To use them, first edit the "inventory" file to contain the hostnames of the machines on which you want kubeadm deployed, and edit the group_vars/ file to set any kubeadm configuration parameters you need.

Then run the playbook, like this:

`ansible-playbook -i inventory site.yml`

This is a very simple playbook. It deploys the following:

1. Installs basic components (docker, kubeadm, contiv)
2. Basic kubernetes cluster using kubeadm (3 nodes is recommended)
3. Contiv CNI in vxlan mode
4. Adds three networks (see group_vars/all)
5. Adds two sample applications (guestbook and wordpress)
