How do I achieve zero-downtime deployments for gRPC?

Achieving zero-downtime deployments for gRPC services is crucial for maintaining consistent availability and performance for users. This can be accomplished by employing techniques such as versioning, graceful shutdowns, and load balancing. Below is an example implementation that demonstrates these principles in practice.


        addService(...);

        // Start the server
        $server->start();

        // Graceful shutdown
        pcntl_signal(SIGTERM, function() use ($server) {
            $server->shutdown();
        });

        // Keep the server running
        while (true) {
            sleep(1);
        }
        ?>
