This repository contains GitHub Actions for working with Atlas.

If you are looking for the old TypeScript-based action, please see the old README.

To learn more about the recommended way to build workflows, read our guide on Modern CI/CD for Databases.

The Atlas GitHub Actions can be composed into workflows to create CI/CD pipelines for your database schema. Workflows will normally begin with the setup-atlas action, which will install the Atlas CLI and optionally login to Atlas Cloud. Followed by whatever actions you need to run, such as migrate lint or migrate apply.

The following examples require you to have an Atlas Cloud account and a push an initial version of your migration directory.

To create an account, first download the Atlas CLI (on Linux/macOS):

curl -sSL https://atlasgo.io/install | sh

For more installation options, see the documentation.

Then, create an account by running the following command and following the instructions:

atlas login

After logging in, push your migration directory to Atlas Cloud:

atlas migrate push --dev-url docker://mysql/8/dev --dir-name my-project

For a more detailed guide, see the documentation.

Finally, you will need an API token to use the Atlas GitHub Actions. To create a token, see the docs.

This example workflow shows how to configure a CI/CD pipeline for your database schema. The workflow will verify the safety of your schema changes when in a pull request and push migrations to Atlas Cloud when merged into the main branch.

If you have the gh CLI installed, you can use the following command to setup a workflow for your repository:

gh extension install ariga/gh-atlas
gh auth refresh -s write:packages,workflow
gh atlas init-action

This will create a pull request with a workflow that will run migrate lint on pull requests and migrate push on the main branch. You can customize the workflow by editing the generated .github/workflows/atlas-ci.yaml file.

Create a new file named .github/workflows/atlas.yaml with the following contents:

name: Atlas CI/CD
on:
  push:
    branches:
      - master # Use your main branch here.
  pull_request:
    paths:
      - 'migrations/*' # Use the path to your migration directory here.
# Permissions to write comments on the pull request.
permissions:
  contents: read
  pull-requests: write

    services:
      # Spin up a mysql:8 container to be used as the dev-database for analysis.
      mysql:
        image: mysql:8
        env:
          MYSQL_DATABASE: dev
          MYSQL_ROOT_PASSWORD: pass

          --health-interval 10s
          --health-start-period 10s
          --health-timeout 5s
          --health-retries 10
    runs-on: ubuntu-latest
    env:
      GITHUB_TOKEN: ${{ github.token }}
    steps:
      - uses: actions/checkout@v3
        with:
          fetch-depth: 0
      - uses: ariga/setup-atlas@v0
        with:
          cloud-token: ${{ secrets.ATLAS_TOKEN }}
      - uses: ariga/atlas-action/migrate/lint@v1
        with:
          dir: 'file://migrations'
          dir-name: 'my-project' # The name of the project in Atlas Cloud
          dev-url: "mysql://root:pass@localhost:3306/dev"
      - uses: ariga/atlas-action/migrate/push@v1
        if: github.ref == 'refs/heads/master'
        with:
          dir: 'file://migrations'
          dir-name: 'my-project' 
          dev-url: 'mysql://root:pass@localhost:3306/dev' # Use the service name "mysql" as the hostname

This example uses a MySQL database, but you can use any database supported by Atlas.
For more examples, see the documentation.

This example workflow shows how to configure a continuous deployment pipeline for your database schema. The workflow will apply migrations on the target database whenever a new commit is pushed to the main branch.

name: Atlas Continuous Deployment
on:
  push:
    branches:
      - master
jobs:
  apply:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
        with:
          fetch-depth: 0
      - uses: ariga/setup-atlas@v0
        with:
          cloud-token: ${{ secrets.ATLAS_TOKEN }}
      - uses: ariga/atlas-action/migrate/apply@v1
        with:
          url: 'mysql://user:${{ secrets.DB_PASSWORD }}@db.hostname.io:3306/db'
          dir: 'atlas://my-project' # A directory stored in Atlas Cloud, use ?tag=<tag> to specify a tag

This example workflow shows how to configure a deployment pipeline for your database schema. This workflow will pull the most recent version of your migration directory from Atlas Cloud and apply it to the target database.
