Git sync

Organization owners and administrators can connect their Web Modeler process applications to GitHub, allowing users to keep their Web Modeler, Desktop Modeler, and official version control projects synced.

Once the basic integration is configured by an organization owner or organization administrator, project administrators and editors can use the built-in button to pull changes from GitHub, integrate contributions from Desktop Modeler users, and merge their own work.

Connect to GitHub​

Create a new GitHub App​

Web Modeler requires a GitHub App to sync changes with your GitHub repository.

Follow the GitHub documentation to create a new GitHub App for your organization or account with the following configuration:

  • Under Webhooks, deselect Active
  • Under Permissions > Repository permissions, enable Read and write for the following options:
    • Commit statuses
    • Contents
    • Pull requests

Click Create GitHub App to finish.

Generate a private key​

  1. In your new application's setting page, navigate to General > Private keys.
  2. Select Generate a private key. This key is automatically downloaded as a .pem file when created, and can be opened in a text editor to copy and paste the contents into Web Modeler.

Install the GitHub App​

  1. In your application's setting page, navigate to Install app.
  2. Click on the Install button for your organization or account.
  3. Select Only select repositories, and choose the repository to sync with Web Modeler.
  4. Once redirected to your application's installation page, copy the Installation ID located at the end of the page's URL: https://github.com/settings/installations/{installation_id}.

Configure GitHub in Web Modeler​

note

An organization administration account (or project administrator in Camunda Self-Managed) is required for the initial GitHub configuration.

  1. Within Web Modeler, navigate to the process application you would like to connect to GitHub, and click Connect GitHub.

  2. Provide the following information in the GitHub Configuration modal:

    • Installation ID: Found in the URL of your GitHub App's installation page.
    • Client ID: Found in your GitHub App's settings page.
    • Private Key: The contents of the .pem file downloaded from your GitHub App's settings page.
    • GitHub repository URL: The URL of the repository you would like to sync with.
    • Branch name: The branch name to use for merging and managing changes.

  3. Click Save Configuration.

note

When synchronizing for the first time with a remote repository that already contains commits, ensure Web Modeler has assigned the correct main process.

When successful, your project will display a new Sync with GitHub button.

The Sync with GitHub within Web Modeler

Sync with GitHub​

note

File synchronization only happens at the root level of the remote repository. Files contained in subfolders will not be synchronized.

Organization owners/administrators, project administrators, and project editors can sync their version of Web Modeler with the connected GitHub repository at any time.

  1. In your connected process application, click Sync with GitHub.
  2. Enter a version number to create a new milestone for your process application. The new milestone will be created prior to pushing your changes to the central repository.
  3. Click Synchronize.

In the case of a merge conflict, select between your local Web Modeler changes and the changes in the remote repository to continue.

Once the pull is complete and any merge conflicts are resolved, Web Modeler will push its changes. The newly created milestone is now accessible via the View milestone button in the success notification.

Manage existing configurations​

Existing GitHub configurations can be edited from the gear icon beside the Sync with GitHub button. Permission to update these settings are limited by the roles within your organization and project.

  • Organization owners/administrators: Edit and update all configuration options.
  • Project administrators - Self-Managed: Edit and update all configuration options.
  • Project administrators - SaaS: Edit and update only the GitHub repository URL and branch name.
  • Project editors: Cannot make changes to the GitHub configuration.

Troubleshooting​

  • Duplicate file names are not allowed for the same file type.
  • Characters with special meaning to Git (for example, /), or characters disallowed by Git, are not allowed in either branch or file names.
  • Any .json file is treated as a Connector template, and the operation will fail if it is not. If the remote repository stores any .json files that are not Connector templates, place them in a subfolder to be automatically ignored by the synchronization process.
  • When synchronizing for the first time with a remote repository that already contains commits, Web Modeler will attempt to select a main process with a file name that matches its own main process. If there is no matching process, Web Modeler will select a process at random from the available .bpmn files. In the event that no .bpmn files exist in the remote repository, Web Modeler will not proceed, and will instead display an error message. Ensure the main process is correctly assigned, especially in cases where a random process has been selected.
  • Actions which alter the SHA of the commit to which Web Modeler is synced (for example, squash) may cause synchronization errors.
  • Timeouts may occur during a sync. In the event of a timeout, close the modal and retry the synchronization.
