How do I implement canary releases for Template repositories?

Canary releases are a deployment strategy that allows you to gradually roll out a new version of your application to a small subset of users before making it available to the entire user base. This technique helps identify potential issues early and minimizes the impact on users.

To implement canary releases for Template repositories, follow these steps:

  1. Set up your template repository with multiple versions, e.g., a stable version and a new feature version.
  2. Use feature flags to enable or disable new features based on user groups or percentages.
  3. Deploy the new version to a small group of users (the "canary group") and monitor its performance.
  4. Analyze feedback and metrics to determine if the new version is ready for full deployment.
  5. If the canary release is successful, gradually increase the rollout to more users.

Here's an example of how you might implement a canary release in PHP:

<?php // Example of feature flag implementation function isFeatureEnabled($feature, $userId) { // Mock feature flag logic $canaryUsers = [1, 2, 3]; // User IDs for canary release return in_array($userId, $canaryUsers); } $userId = 1; // Example user ID if (isFeatureEnabled('new_feature', $userId)) { echo "New feature is enabled for you!"; } else { echo "You're using the stable version."; } ?>
