AKS_Cluster_Terraform_deployment

Objective

Deploy Azure Kubernetes Cluster using terraform script Deploying ask cluster from azure portal can take long time. To automate this process, I have written terraform script.

You can setup terraform in your local computer and run this script to deploy ASK clusters

Steps to setup code in local computer

Setup Terraform

1. Install terraform based on your OS.

https://developer.hashicorp.com/terraform/tutorials/aws-get-started/install-cli

2. Clone the repo

Git clone https://github.com/incredulouss/AKS_Cluster_Terraform_deployment.git

3. Now run terraform init to setup everything

terraform init

Configure Environment tfvars file

There is a file called env.tfvars , it will have all the environment variables. You can configure your AKS cluster based on these values.

For authentication to Azure I am using Service principle

•	subscription_id = "xxx.xxx.xxx.xxx"
•	client_id       = "xxx.xxx.xxx.xxx"
•	client_secret   = "xxx.xxx.xxx.xxx"
•	tenant_id       = "xxx.xxx.xxx.xxx"

These values will authenticate to azure.

Note – Make sure the SP has required permission (Contributor Role) to make deployments in resource group

Extra Configuration Features

You can do some changes in main.tf to have more configurations in AKS cluster

Setup K8S Networking - In the current main.tf, the networking is setup to Kubenet. You can change it to CNI by uncommenting the CNI snippet and commenting kubenet snippet
Autentication - Currently using managed idenetity, for more granular control you can use service principle

Terraform Commands to deploy script

•	terraform plan -var-file=”env.tfvars”
•	terrfarom apply -var-file=”env.tfvars”
