Exploring Terraform State Functionality

1. Check that Terraform is installed and functioning properly using the terraform version command.
2. Check that the Kubernetes backedn process minikube is running properly using the minikube status command.

1. The Terraform code required for this lab has already been cloned onto the provided VM.
2. Switch to the directory where the code is located to perform the remaining tasks:

lab_code/section2-hol1

3. View the code in the main.tf file to see what has been configured for deployment.

1. Initialize the working directory and download the required providers.
2. Review the actions that will be performed when code is deployed using the terraform plan command.
3. Deploy the code with the terraform apply command.
4. List the files and verify that the state file was created.
5. List all the resources being tracked by the Terraform state file using the terraform state command.
6. View the replicas being tracked by the Terraform state file and note the number.
7. Modify the replicas attribute in the Terraform code and deploy the code again.
8. View the replicas being tracked by the Terraform state file and verify that the number has changed.
9. Remove the infrastructure you created using the terraform destroy command. However, note that Terraform leaves behind a terraform.tfstate.backup file in case you need to recover to the last deployed Terraform state.

As you make your way through this objective, you may also choose to verify that the number of pods configured in the code were created and that this number changes as you modify the replicas attribute in your code using the kubectl command.
