Connect Migration Directories

The following guide explains how to connect a migration directory to Atlas Cloud. Once connected, Atlas provides a list of features enabling users to seamlessly audit their migration history, run continuous migration linting on their PRs, monitor executed migrations and receive webhook notifications, among other capabilities.

To get started, you need to sync your migration directory to the Schema Registry in Atlas Cloud.

Login to Atlas Cloud​

Firstly, you'll need to log in to Atlas. If it's your first time, you'll be prompted to create both an account and a workspace (organization):

atlas login

Push the migration directory​

After logging in, we can push the migration directory to Atlas Cloud to persist its state. This allows it to be read by Atlas CLI later on in our CI/CD pipelines or by other developers on our team.

atlas migrate push app \
  --dev-url "docker://postgres/15/dev?search_path=public"
note

For the purpose of this example, we have named our migration directory app, but you can choose a different name containing only alphanumeric characters, dashes, and underscores.

atlas migrate push

Migration Directory created with atlas migrate push

Setup CI​

After setting up your migration directory, the next step is to add Atlas to your CI pipeline. This ensures that the migration files are checked and reviewed before being merged into the main branch. Below are the supported CI platforms Atlas currently supports:

Setup CD​

Atlas Cloud streamlines deploying migrations by providing a single place to manage migrations for all your services. After connecting your migration directory to Atlas Cloud, it is automatically synced to a central location on every commit to your main branch. Once this setup (which takes less than one minute) is complete, you can deploy migrations from Atlas Cloud to any environment with a single command (or using popular CD tools such as Kubernetes and Terraform).

For more information, visit the Introduction to schema migrations deployments in the guides section.

Slack Integration​

You can use Slack Webhooks to receive updates in your Slack channel about schema changes, CI runs and deployment statuses of your migration directory. Make sure you have a Slack incoming webhook configured (you can create one here).

Select your migration directory, go to "Webhooks" and click on Add Webhook.

Screenshot example

Select the Slack integration, Choose the events you want to be notified about and insert your webhook URL. Click on Add Webhook to confirm.

Once the Webhook is created, you will be redirected to the Webhooks page. Select a webhook to edit its configuration and to view its delivery history.

Screenshot example

You can also test the webhook by clicking on Send Ping.
