To version the changes you make in your environments, Knock uses a commit model. When you make a change to a workflow or a layout in the Knock dashboard, you'll need to commit it to your development environment before those changes will appear in workflows triggered via the API.
After you modify a resource, you'll see a "Save" button that allows you to store those changes. When you're ready to permanently store your updates with version control, they should be committed with the "Commit to development" button that will come into focus after changes have been saved.
A few things to note:
- Channel configurations, branding, and variables do not need to be committed, as they live at the account-level. This means that if you make a change to a channel configuration, it will update immediately on notifications sent in that environment.
- Any changes you have saved but not yet committed will apply when you're using the test runner. This allows you to test your latest changes before you commit them to your development environment.
- You can work with Knock resources outside of your dashboard if you prefer. We offer both a Management API and a command line interface for interacting with Knock resources programmatically. The commit model applies to all methods of interacting with Knock resources, whether directly in the dashboard or with the Management API or CLI.
Clicking the "Commit to development" button will show you a view of changes between your current commit and the most-recent version of the resource that you're updating. Commit diffs are also available on your full commit log (viewable on the "Commits" page in your dashboard), so you can view the commit history for a resource and know exactly what was changed with each commit.
Knock is designed to allow large teams to create and manage notifications at scale. That means that notifications changes must be versioned, tested, and promoted to production environments, so that if there are any issues they can be rolled back with ease.
Knock uses a model where all changes to the production environment must be promoted and cannot be made directly. Changes must be made in the development environment, then staged and tested before being rolled out (similar to a git-based workflow).
To promote a committed change to a higher environment, navigate to the "Commits" page in your Knock dashboard and click on "Unpromoted changes". Here you'll see a list of commits that are ready for promotion. Clicking "View commit" on a given commit will show you a commit diff for that change, and clicking the "Promote to [environment]" button will promote the staged commit to the next-higher environment (whose name is displayed on the button).
A typical deployment lifecycle in Knock looks like:
- Introduce any backend changes to support a new workflow (users and preference properties)
- Build the workflow in a dev environment in Knock and commit it to that environment
- Test the workflow
- When you're ready to go live, promote the workflow to production
