This collection helps you to create a kubernetes cluster by Kubeadm on AWS.

This collection contains two roles

1. awsrole
2. kube_cluster

This roles helps to launch instances on aws cloud al you need to do is follow below steps

1. Configure the ansible.cfg like this

   [defaults]
   host_key_checking = false
   remote_user: "username"
   private_key_file = "location of private key"
   
   [privilege_escalation]
   become = true
   become_method = sudo
   become_user = root
   become_ssh_pass = false
   

2. Install the given requirements

3. Download the ec2.py and ec2.ini and make them executable (this will dynamically fetch the hosts from aws)

4. Set the credential of aws by the using below commands

   $ export AWS_ACCESS_KEY_ID='YOUR_AWS_API_KEY'
   $ export AWS_SECRET_ACCESS_KEY='YOUR_AWS_API_SECRET_KEY'

These are the variables to be set in vars/main.yml

This playbook launch

- hosts: localhost
  roles:
     - { role: amanrathi1.awsrole }

This role helps in configuring both master and slave, you have to change only the node_name variable.

DO NOT change the default path of the collection if you are doing so, don't forget to provide the new path of collection roles in var role_path in kube_cluster role.

node_name: master #for configuring master node

node_name: slave #for configuring slave node

While configuring the master node the token in variable file automatically updated and avaible for slave nodes to be joined, which removes the manual process in between

NONE

node_name

network_cidr #don't change default one if you are using official flannel cni

While configuring master the token variable will be automatically updated for future use

NONE

example to configure master node

- hosts: master
  vars:
    node_name: master
  roles:
     - { role: amanrathi1.kubernetes.kube_cluster }

example to configure slave node

- hosts: slave
  vars:
    node_name: slave
  roles:
     - { role: amanrathi1.kubernetes.kube_cluster }
