Goal of the project

• Use Terraform.
• Use and dive into Ansible.
• Deploy a from-scratch Kubernetes cluster against multiple cloud providers.

TODO

• The node must install Calico networking component.
• The nodes should join the kube cluster automatically.
• The cluter should have an LB to expose Nginx as first app.
• Decouple files to adapt from different cloud providers.

disk_size = 10\*1024 # MG to GB, increase first operand to increase disk size
region = "" # One region that is provided by your provider
instance_type = "" # Instance code from your provider
auth_keys = [] # SSH public key to add in the known_hosts node's file
root_pwd = "" # Explicit.
