Zorluk: KolayImplementing Infrastructure as Code using Terraform and Deployment Manager

When configuring Terraform to use a Google Cloud Storage bucket as a secure remote backend for team collaboration, in what sequence should you execute the provisioning and configuration workflow?

  1. 1Create a dedicated Google Cloud Storage bucket with Object Versioning enabled.
  2. 2Configure the terraform backend 'gcs' block in your Terraform code with the bucket name.
  3. 3Run 'terraform init' to initialize the directory and migrate state to the GCS bucket.
  4. 4Run 'terraform plan' to verify configuration state locking and execution against the remote backend.

Cevap

The correct order begins with creating the GCS bucket with Object Versioning, followed by writing the backend 'gcs' configuration block in Terraform, then running 'terraform init' to migrate state, and finally running 'terraform plan' to verify state locking and plan execution against the remote backend.
Establishing a remote Terraform state backend requires the storage infrastructure to exist first (GCS bucket creation with Object Versioning), declaring the storage destination inside the Terraform configuration, initializing the directory with 'terraform init' to establish remote state locking, and executing 'terraform plan' to verify operational readiness.

Adım Adım Çözüm

1
Provision GCS Storage Bucket
A secure GCS bucket is available in GCP with Object Versioning enabled to prevent state corruption.
Terraform cannot store state in a GCS bucket that does not yet exist.
2
Declare Backend Configuration
The terraform block specifies backend 'gcs' with the target bucket and prefix.
Terraform requires code configuration to know where the state file should be stored remotely.
3
Initialize Terraform Backend
Terraform downloads the GCS provider plugin and migrates local state to the remote GCS bucket.
The initialization command establishes the remote backend connection.
4
Validate State Execution Plan
Terraform acquires a state lock on the GCS bucket and checks proposed changes against remote state.
Running plan confirms that remote state locking and reading work seamlessly.
