HA Kubernetes Cluster in 15 Minutes

Using AWS EC2 with Terraform and Ansible.

I was thinking about this project for a long time and finally, I was able to find some time to put things together. I know, these days it’s not a big deal to quickly spin up a Kubernetes cluster with most of the cloud service providers. But we don’t have full control over them as they are managed by cloud providers. Sometimes we all got requirements to change bits and pieces here and there to try new things in Kubernetes clusters. It’s always nice if we can quickly spin up a k8 cluster where we can manage all the pieces as we need.

At the time of this article, I managed to complete the Highly Available multi-master Kubernetes cluster as per the above architecture diagram. Once you apply the Terraform code, it will do the infrastructure provisioning and then the cluster configurations with Ansible. Although, I didn’t include the Ingress traffic management part and the post cluster configuration in this repo as I have already discussed them in the article linked below.
