CircleCI Orbs

CircleCI Orbs are reusable packages of CircleCI configuration that can be shared across projects. They provide a way to simplify your CircleCI configuration by encapsulating common tasks into a single line of code.

Atlas provides a number of Orbs to help you integrate Atlas into your CircleCI workflows.

ActionUse Case
atlas-orb/setupInstall Atlas and authenticate with Atlas Cloud
atlas-orb/migrate_pushPush your migration directory to Atlas Cloud (atlasgo.cloud)
atlas-orb/migrate_lintLint migration changes with Atlas (Required atlas login)
atlas-orb/migrate_applyApply migrations to a database
atlas-orb/migrate_downRevert migrations to a database.
atlas-orb/migrate_testTest migrations to a database.
atlas-orb/schema_testTest schema to a database.

atlas-orb/setup​

The atlas-orb/setup action can be used to install the Atlas CLI and authenticate with Atlas Cloud.

atlas-orb/migrate_lint (Required atlas login)​

Teams using CircleCI that wish to ensure all changes to their database schema are safe can use the atlas-orb/migrate_lint CircleCI Orb.

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. Read more about the consistency checks in the section below.
  • Detect whether destructive or irreversible changes have been made or whether they are dependent on tables'
    contents and can cause a migration failure.

Usage​

Add .circleci/config.yml to your repo with the following contents:

version: 2.1
orbs:

jobs:
  push-dir:
