• Update atmos terraform plan command
• Add --skip-planfile flag to atmos terraform plan command
• Add ATMOS_COMPONENTS_TERRAFORM_PLAN_SKIP_PLANFILE ENV variable
• Add components.terraform.plan.skip_planfile section to atmos.yaml
• Update docs
• Add tests

why

• Support Terraform Cloud

• Allow skipping writing the plan to a file by not passing the -out flag to Terraform when executing the atmos terraform plan command. Set the flag to true when using Terraform Cloud since the -out flag is not supported. Terraform Cloud automatically stores plans in its backend"

• Allow controlling the behavior in three ways:

  • Globally by setting components.terraform.plan.skip_planfile to true in atmos.yaml

    components:
      terraform:
        auto_generate_backend_file: true
        plan:
          # Skip passing the `-out=FILENAME` flag when executing the `terraform plan` command.
          # Set it to `true` when using Terraform Cloud since the `-out` flag is not supported.
          # Terraform Cloud automatically stores plans in its backend.
          skip_planfile: true

  • Via the ATMOS_COMPONENTS_TERRAFORM_PLAN_SKIP_PLANFILE ENV variable

      ATMOS_COMPONENTS_TERRAFORM_PLAN_SKIP_PLANFILE=true atmos terraform plan <component> -s <stack>

  • By passing the --skip-planfile=true flag on the command line

     atmos terraform plan <component> -s <stack> --skip-planfile=true
