  Migrating from v1 to v2

  The notable changes in v2 are:

  • v2 works only with atmos >= 1.63.0
  • v2 drops install-terraform input because terraform is not required for affected stacks call
  • v2 drops atmos-gitops-config-path input and the ./.github/config/atmos-gitops.yaml config file. Now you have to use GitHub Actions environment variables to specify the location of the atmos.yaml.

  The following configuration fields now moved to GitHub action inputs with the same names

  name
  atmos-version
  atmos-config-path

  The following configuration fields moved to the atmos.yaml configuration file.

  name	YAML path in atmos.yaml
  aws-region	integrations.github.gitops.artifact-storage.region
  terraform-state-bucket	integrations.github.gitops.artifact-storage.bucket
  terraform-state-table	integrations.github.gitops.artifact-storage.table
  terraform-state-role	integrations.github.gitops.artifact-storage.role
  terraform-plan-role	integrations.github.gitops.role.plan
  terraform-apply-role	integrations.github.gitops.role.apply
  terraform-version	integrations.github.gitops.terraform-version
  enable-infracost	integrations.github.gitops.infracost-enabled
  sort-by	integrations.github.gitops.matrix.sort-by
  group-by	integrations.github.gitops.matrix.group-by

  For example, to migrate from v1 to v2, you should have something similar to the following in your atmos.yaml:

  ./.github/config/atmos.yaml

  # ... your existing configuration
  
  integrations:
    github:
      gitops:
        terraform-version: 1.5.2
        infracost-enabled: false
        artifact-storage:
          region: us-east-2
          bucket: cptest-core-ue2-auto-gitops
          table: cptest-core-ue2-auto-gitops-plan-storage
          role: arn:aws:iam::xxxxxxxxxxxx:role/cptest-core-ue2-auto-gitops-gha
        role:
          plan: arn:aws:iam::yyyyyyyyyyyy:role/cptest-core-gbl-identity-gitops
          apply: arn:aws:iam::yyyyyyyyyyyy:role/cptest-core-gbl-identity-gitops
        matrix:
          sort-by: .stack_slug
          group-by: .stack_slug | split("-") | [.[0], .[2]] | join("-")

  .github/workflows/main.yaml

    - name: Plan Atmos Component
      uses: cloudposse/github-action-atmos-terraform-apply@v2
      with:
        component: "foobar"
        stack: "plat-ue2-sandbox"
        atmos-config-path: ./rootfs/usr/local/etc/atmos/
        atmos-version: 1.63.0

  This corresponds to the v1 configuration (deprecated) below.

  The v1 configuration file ./.github/config/atmos-gitops.yaml looked like this:

  atmos-version: 1.45.3
  atmos-config-path: ./rootfs/usr/local/etc/atmos/
  terraform-state-bucket: cptest-core-ue2-auto-gitops
  terraform-state-table: cptest-core-ue2-auto-gitops
  terraform-state-role: arn:aws:iam::xxxxxxxxxxxx:role/cptest-core-ue2-auto-gitops-gha
  terraform-plan-role: arn:aws:iam::yyyyyyyyyyyy:role/cptest-core-gbl-identity-gitops
  terraform-apply-role: arn:aws:iam::yyyyyyyyyyyy:role/cptest-core-gbl-identity-gitops
  terraform-version: 1.5.2
  aws-region: us-east-2
  enable-infracost: false
  sort-by: .stack_slug
  group-by: .stack_slug | split("-") | [.[0], .[2]] | join("-")  

  And the v1 GitHub Action Workflow looked like this.

  .github/workflows/main.yaml

    - name: Plan Atmos Component
      uses: cloudposse/github-action-atmos-terraform-apply@v1
      with:
        component: "foobar"
        stack: "plat-ue2-sandbox"
        atmos-gitops-config-path: ./.github/config/atmos-gitops.yaml
