github-action-atmos-terraform-select-components: A Makefile repository from Cloud Posse

GitHub Action that outputs list of Atmos components by jq query

Tip

👽 Use Atmos with Terraform

Cloud Posse uses atmos to easily orchestrate multiple environments using Terraform.
Works with Github Actions, Atlantis, or Spacelift.

Watch demo of using Atmos with Terraform

Example of running atmos to manage infrastructure from our Quick Start tutorial.

Introduction

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"
  }
]

Usage

Config

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

integrations:
  github:
    gitops:
      opentofu-version: 1.7.3
      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("-")

Important

Please note! This GitHub Action only works with atmos >= 1.63.0. If you are using atmos < 1.63.0 please use v1 version of this action.

Support OpenTofu

This action supports OpenTofu.

Important

Please note! OpenTofu supported by Atmos >= 1.73.0. For details read

To enable OpenTofu add the following settings to atmos.yaml

Set the opentofu-version in the atmos.yaml to the desired version
Set components.terraform.command to tofu

Example

components:
  terraform:
    command: tofu

...

integrations:
  github:
    gitops:
      opentofu-version: 1.7.3
      ...

GitHub Actions Workflow Example

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: ${{ steps.components.outputs.matrix }}
      steps:
        - name: Selected Components
          id: components
          uses: cloudposse/github-action-atmos-terraform-select-components@v2
          with:
            atmos-config-path: "${{ 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 }}"

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: Selected Components
  id: components
  uses: cloudposse/github-action-atmos-terraform-select-components@v2
  with:
    atmos-config-path: ./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(",")'

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: Selected Components
  id: components
  uses: cloudposse/github-action-atmos-terraform-select-components@v1
  with:
    atmos-gitops-config-path: ./.github/config/atmos-gitops.yaml
    jq-query: 'to_entries[] | .key as $parent | .value.components.terraform | to_entries[] | select(.value.settings.github.actions_enabled // false) | [$parent, .key] | join(",")'

Migrating from `v0` to `v1`

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.

name
`atmos-version`
`atmos-config-path`

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.

Important

In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic approach for updating versions to avoid unexpected changes.
