TerraformIaCHCLState Management 5 min čtení

Remote state, locking, moved blocks, import a CI/CD pipeline.

Remote State¶

terraform {
  backend "s3" {
    bucket         = "mycompany-tf-state"
    key            = "prod/infra.tfstate"
    region         = "eu-west-1"
    dynamodb_table = "terraform-locks"
    encrypt        = true
  }
}

Import a Moved¶

# Import (TF 1.5+)
import {
  to = aws_s3_bucket.main
  id = "my-existing-bucket"
}
# Moved — refactoring bez destroy
moved {
  from = aws_instance.web
  to   = module.compute.aws_instance.web
}

CI/CD¶

name: Terraform
on: [pull_request, push]
jobs:
  terraform:
    steps:
      - run: terraform init
      - run: terraform fmt -check
      - run: terraform plan -out=tfplan
      - run: terraform apply -auto-approve tfplan
        if: github.ref == 'refs/heads/main'

Shrnutí¶

Pokročilý TF = remote state + CI/CD + import pro brownfield + moved pro refactoring.
