GitHub Action that outputs list of Atmos components by jq query.

For example following query will fetch components that have in settings set github.actions_enabled: true:

.value.settings.github.actions_enabled // false

Output of this action is a list of basic component information. For example:

[
  {
  "stack": "plat-ue2-sandbox",
  "component": "test-component-01",
  "stack_slug": "plat-ue2-sandbox-test-component-01",
  "component_path": "components/terraform/s3-bucket"
  }
]

The action expects the atmos gitops configuration file to be present in the repository in ./.github/config/atmos-gitops.yaml. The config should have the following structure:

  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("-")  

In following GitHub workflow example first job will filter components that have settings github.actions_enabled: true and then in following job stack_slug will be printed to stdout.

  jobs:
    selected-components:
      runs-on: ubuntu-latest
      name: Select Components
      outputs:
        matrix: ${{ steps.components.outputs.matrix }}
      steps:
        - name: Selected Components
          id: components
          uses: cloudposse/github-action-atmos-terraform-select-components@v0
          with:
            atmos-config-path: "${{ github.workspace }}/rootfs/usr/local/etc/atmos/"
            jq-query: 'to_entries[] | .key as $parent | .value.components.terraform | to_entries[] | select(.value.settings.github.actions_enabled // false) | [$parent, .key] | join(",")'

    print-stack-slug:
      runs-on: ubuntu-latest
      needs:
        - selected-components
      if: ${{ needs.selected-components.outputs.matrix != '{"include":[]}' }}
      strategy:
        matrix: ${{ fromJson(needs.selected-components.outputs.matrix) }}
      name: ${{ matrix.stack_slug }}
      steps:
        - name: echo 
          run:
            echo "${{ matrix.stack_slug }}"

1. v1 replaces the jq-query input parameter with a new parameter called selected-filter to simplify the query for end-users. Now you need to specify only the part used inside of the select(...) function of the jq-query.

2.v1 moves most of the inputs to the Atmos GitOps config path ./.github/config/atmos-gitops.yaml. Simply create this file, transfer your settings to it, then remove the corresponding arguments from your invocations of the cloudposse/github-action-atmos-terraform-select-components action.

If you want the same behavior in v2 as in v1 you should create config ./.github/config/atmos-gitops.yaml with the same variables as in v0 inputs.

  - name: Selected Components
    id: components
    uses: cloudposse/github-action-atmos-terraform-select-components@v1
    with:
      atmos-gitops-config-path: ./.github/config/atmos-gitops.yaml
      select-filter: '.settings.github.actions_enabled // false'

Which would produce the same behavior as in v2, doing this:

  - name: Selected Components
    id: components
    uses: cloudposse/github-action-atmos-terraform-select-components@v0
    with:
      atmos-config-path: "${{ github.workspace }}/rootfs/usr/local/etc/atmos/"
      jq-query: 'to_entries[] | .key as $parent | .value.components.terraform | to_entries[] | select(.value.settings.github.actions_enabled // false) | [$parent, .key] | join(",")'

Please note that the atmos-gitops-config-path is not the same file as the atmos-config-path.
