abcxyz Common Packages

"abcxyz Common Packages" is not an official Google product.

abcxyz pkg provides a place for sharing common abcxyz packages across the abcxyz repos.

GitHub Actions

There are reusable workflows inside ./.github/workflows, which encapsulate common CI/CD logic to reduce repetition. For security, the reusable workflows are pinned to specific references using ratchet.

The reusable workflows use a default runner image of ubuntu-latest, since this works for most use cases. We do not recommend customizing the runner image unless you need additional performance. To customize the runner image, set the runs-on key as an input to the reusable workflow to a valid JSON string representing the GitHub runs-on configuration. Because GitHub Actions reusable workflows do not support complex input types, these values must be a valid JSON-encoded string.

# Example of using a different runner
uses: 'abcxyz/pkg/.github/workflows/workflow.yml@main'
with:
  runs-on: '"macos-latest"' # double quoting is required

# Example of using a self-hosted runner
uses: 'abcxyz/pkg/.github/workflows/workflow.yml@main'
with:
  runs-on: '["self-hosted", "ubuntu-22.04"]'

# Example of using a label
uses: 'abcxyz/pkg/.github/workflows/workflow.yml@main'
with:
  runs-on: '{"label": "4-core"}'

go-lint.yml

Use this workflow to perform basic Go linting checks:

on:
  push:
    branches:
      - 'main'
    paths:
      - '**.go'
  pull_request:
    branches:
      - 'main'
    paths:
      - '**.go'
  workflow_dispatch:

jobs:
  lint:
    uses: 'abcxyz/pkg/.github/workflows/go-lint.yml@main'

Linting is done via golangci-lint. If a .golangci.yml file exists at the root of the repository, it uses those linter settings. Otherwise, it uses a set of sane defaults.

go-test.yml

Use this workflow to perform basic Go tests:

on:
  push:
    branches:
      - 'main'
    paths:
      - '**.go'
  pull_request:
    branches:
      - 'main'
    paths:
      - '**.go'
  workflow_dispatch:

jobs:
  lint:
    uses: 'abcxyz/pkg/.github/workflows/go-test.yml@main'

Testing is done via the go test command with:

• Test caching disabled
• Test shuffling enabled
• Race detector enabled
• A 10 minute timeout

terraform-lint.yml

Use this workflow to perform basic Terraform linting checks:

on:
  push:
    branches:
      - 'main'
    paths:
      - '**.tf'
  pull_request:
    branches:
      - 'main'
    paths:
      - '**.tf'
  workflow_dispatch:

jobs:
  lint:
    uses: 'abcxyz/pkg/.github/workflows/terraform-lint.yml@main'
    with:
      terraform_version: '1.2'
      directory: './terraform'

If you have multiple Terraform configurations, repeat the stanza for each directory. Linting is done in two steps:

1. Run terraform validate. This will fail if the Terraform is invalid.

2. Run terraform fmt and check the git diff. This will will if the Terraform file is not formatted. On failure, the output will include the diff.

want-lgtm-all.yml

Use this workflow to require an approval from all requested reviewers:

on:
  pull_request:
    types:
      - 'opened'
      - 'edited'
      - 'reopened'
      - 'synchronize'
      - 'ready_for_review'
      - 'review_requested'
      - 'review_request_removed'
  pull_request_review:
    types:
      - 'submitted'
      - 'dismissed'
      - 'edited'

concurrency:
  group: '${{ github.workflow }}-${{ github.event_name }}-${{ github.head_ref || github.ref }}'
  cancel-in-progress: true

permissions:
  actions: 'write'
  pull-requests: 'read'

jobs:
  want-lgtm-all:
    uses: 'abcxyz/pkg/.github/workflows/want-lgtm-all.yml@main'

When creating a pull request, include the text want_lgtm=all in the body to require an approval from all requested reviewers.
