Requirements

To follow the steps in this guide, you’ll need:

  • An existing git repository in GitHub, Git Lab, or Azure DevOps
  • Permissions in your git provider that allow you to:
    • Add webhooks to repositories
    • Add deploy/SSH keys to repositories
    Refer to the documentation for your git provider for information about their user permissions.

​
Step 1: Retrieve the repository’s SSH URL

  1. In your browser, navigate to the GitHub or GitLab git repository you want to connect to Omni.
  2. Click the Code button.
  3. In the modal that displays, locate the SSH option.
Keep this page open - you’ll need it in the next step.
  1. In your browser, navigate to the Azure DevOps git repository you want to connect to Omni.
  2. Click the Clone button near the top right corner of the page.
  3. Click the SSH option to display the repository’s SSH URL.

​
Step 2: Connect the repository to Omni

  1. In Omni, click Develop.
  2. Click the model you want to connect to git.
  3. In the model IDE, click Model > Git settings.
  4. You’ll be prompted to enter connection details for the repository:
    • SSH URL - Copy and paste the repository’s SSH URL from Step 1
    • Base Branch - Enter the name of default branch for the repository. Omni will default to main unless a different name is specified.
  5. Click Configure Git.

  2. Fill in the deploy key fields as follows:
    • Title - Enter a descriptive title to help you identify what the key is used for. For example, Omni Snowflake Model
    • Key - Copy the Public key from the Omni Git settings page and paste it into this field.
    • Grant write permissions to this key - Check this box, which will allow Omni to push changes made in Omni to the repository
  3. Click Add key.
  1. Browse to the Azure DevOps web portal (ex: https://dev.azure.com/<your-org-name>/).
  2. Click the User settings icon next to your avatar in the top right corner of the page.

  7. When finished, click Add webhook.
Next, you’ll create three webhook subscriptions for the Azure DevOps repository, one for each of the following event types:
  • Pull request created
  • Pull request updated
  • Repository status updated

​
Step 1: Create the webhook subscription

    2. Pull request updated
    3. Repository status updated
  2. Select the Repository you want to connect to Omni.
  3. If the Target branch field displays, select the main branch.
  4. When finished, click Next.

​
Step 3: Configure the Action

On the Action screen, fill in the fields as follows:
  • URL - Copy and paste the Webhook URL from the Omni Git settings page

    • Repository status updated - x-azuredevops-omni-event:update-status
When finished, click Finish to create the webhook.

​
Part 4: Repeat steps 1-3

Repeat these steps for each of the three webhook subscription types.

​
Step 5: Test the connection
