This blog post, based on a YouTube video tutorial, explores how to store Terraform state in a remote Azure storage account.



Why Store Terraform State Remotely?

  • Local storage creates issues when working in a team.
  • Two team members modifying the same state file can lead to conflicts.
  • Local storage deletion can cause problems.

Benefits of Remote Storage:

  • Centralized location accessible by all team members.
  • Improved collaboration and state management.

How to Store Terraform State in Azure Storage

  1. Prerequisites:
    • Azure subscription
    • Azure storage account
    • Terraform installed
  2. Configure Backend with Terraform:
    • Create a backend.tf file.
    • Specify the storage account details:
      • Resource group name
      • Storage account name
      • Container name
      • Key (optional)
  3. Set Access Key as Environment Variable:
    • Use Azure CLI to retrieve the storage account access key.
    • Set the key as an environment variable for Terraform to access the storage account.
  4. Initialize Terraform:
    • Run terraform init to initialize Terraform with the remote backend configuration.
  5. Manage Your Resources:
    • Use terraform plan and terraform apply to plan and apply infrastructure changes.
    • The state file is created and stored in the Azure storage container.

Verifying Remote Storage:

  • Access the Azure storage account container.
  • The container should contain a terraform.tfstate file representing the Terraform state.

Key Points:

  • Remote storage ensures state locking and consistency.
  • Consider using Azure Key Vault for secure storage and access control of the storage account key.
