k8s_cluster_role

k8s master and worker cluster over aws using ansible roles

How to use the role:

This repository focuses on configuring k8s cluster (1 master and 2 slave nodes) over AWS.

If you already have precreated AWS instances than you can simply put their IPs in ip.txt file and execute final.yml playbook using the command:

ansible-playbook final.yml

But if you do not have AWS pre-created instances then I've created another playbook which will not only launch master and slave nodes but also update their IPs dynamically in inventory file (ip.txt) and then configure k8s cluster on it.

So for this you need to follow these steps:

1. In vars.yml fill all the AWS instance related details which are required to launch the instances.

2. In the same directory (i.e., k8s_cluster_role), make ansible-vault to store the AWS IAM user access_keyand secret_key. Create file with the name credentials.yml only, because it is hard-coded in the program using the command:

ansible-vault create credentials.yml

And inside this file input AWS access_key and secret_key in the following format:

access_key: <access_key>
secret_key: <secret_key>

First playbook will create instances in AWS and we can run the playbook using the command:

ansible-playbook --ask-vault-pass ec2_create.yml

And next, you need to run the playbook final.yml using the command:

ansible-playbook final.yml

That's all folks... Thankyou for reading :)

I would also like to thank Prithviraj Singh for his help and guidance throughout this project ^_^
