How do I implement canary releases for Jaeger?

Implementing canary releases for Jaeger allows for safe and gradual deployment of new versions of your services. This strategy helps in minimizing any potential impact by exposing only a small percentage of users to the new release while monitoring for errors or issues.

// Example of canary release implementation for Jaeger // Step 1: Define your service versions $currentVersion = "service-1.0"; $canaryVersion = "service-1.1"; // Step 2: Set up routing rules // This is a pseudo-code representation of routing requests routeRequest($request) { if (shouldRouteToCanary()) { // Route to the canary version return callService($canaryVersion, $request); } else { // Route to the stable version return callService($currentVersion, $request); } } // Function to determine if the request should go to the canary version function shouldRouteToCanary() { // Randomly allow 10% of traffic to the canary version return rand(1, 10) === 1; } // Function to call a service with a specific version function callService($version, $request) { // Implement the logic to call the service based on the version // Here you would typically use a service discovery mechanism or direct URL return "Calling $version with request: " . json_encode($request); }
