Provisioning kubernetes with Terraform

This project helps to provision the kubernetes and manage the kubernetes deployment with the help of terraform in Azure cloud

Initial setup in AZURE CLI

1 open azure portal
2 setup terraform
3 Redeem Azure Pass
4 Open Azure Cloud Shell - Bash Prompt
5 Now Create Azure Contributor Service Principal for terraform Auth.
6 az login 
7 az account list -o table 
8 az account set -s "<subscription-id>"
9 az ad sp create-for-rbac --role="Contributor" --scopes="/subscriptions/<subscription_id>"
## Export the Azure Auth Variable in your bash RC.
10 export ARM_CLIENT_SECRET="<<password>>"
   export ARM_CLIENT_ID="<<appID>>"
   export ARM_SUBSCRIPTION_ID="<<subscriptionID>>"
   export ARM_TENANT_ID="<<tenant>>"
11 Initialize the Bashrc Variables
12 source ~/.bashrc
13 git clone into azure cli

Automate the kubernetes management using Terraform

cd PwC-capstone-project
terraform init
terraform apply --auto-approve

Deploy basic NGINX App in K8

mv kubeconfig ~/.kube/config 
if this command gives error
try running following commands from present directory
mkdir ~/.kube
mv kubeconfig ~/.kube/config
kubectl create -f deployment.yaml
kubectl get pods
