A GitHub Action for Atlas.

This action is used for linting migration directories using the atlas migrate lint command. This command validates and analyzes the contents of migration directories and generates insights and diagnostics on the selected changes:

• Ensure the migration history can be replayed from any point at time.
• Protect from unexpected history changes when concurrent migrations are written to the migration directory by multiple team members.
• Detect whether destructive or irreversible changes have been made or whether they are dependent on tables'
  contents and can cause a migration failure.

This action supports analyzing migration directories in formats accepted by different schema migration tools:

• Atlas
• golang-migrate
• goose
• dbmate

Add .github/workflows/atlas-ci.yaml to your repo with the following contents:

  # Run whenever code is changed in the master branch, 
  # change this to your root branch.

Configure the action by passing input parameters in the with: block.

Sets the directory that contains the migration scripts to analyze.

Sets the format of the migration directory. Options: atlas (default), golang-migrate, goose or dbmate. Coming soon: flyway, liquibase.

The URL of the dev-database to use for analysis.

• Read about Atlas URL formats
• Read about dev-databases

Use the latest mode to decide which files to analyze. By default, Atlas will use git-base to analyze any files that are present in the diff between the base branch and the current.

Unless this option is set, the base branch (master/main/etc) must be checked out locally or you will see an error such as:

Atlas failed with code 1: Error: git diff: exit status 128

The full list of input options can be found in action.yml.
