In this deployment, I want to store the state file remotely in Azure; I will be storing my state file in a Storage Account container called:- tfstatedevops, Lets deploy the required storage container called tfstatedevops in Storage Account tamopstf inside Resource Group tamopstf. Which later on, can be reused to perform authenticated tasks (like running a Terraform deployment ). This has az, jq and terraform pre-installed and defaults to using MSI so the whole VM is authenticated to a subscription. To be able to deploy to Azure you’d need to create a service principal.

My example Pipeline consists of snippets from this GitHub, Validate:- To Validate my Terraform code, if validation fails the pipeline fails (consists of Terraform init & validate), Deploy:- if Validation is successful, it moves to next stage of pipeline which is Deploying the Terraform code to deploy required Azure Resources (consists of Terraform plan & deploy), Throughout the Pipeline, notice my reference to the previously created Storage Account, Resource Group and container for the Terraform state file along with the newly created SPN? You will need to be at the Owner or equivalent level to complete this section. There is another less frequently used argument that you can specify in the provider block called alias.
