What we discovered was a complex dance between Kubernetes pod lifecycle, ALB target group health checks, and application shutdown behavior that, when misaligned, creates windows of unavailability during routine operations.</p> <p>This post details our journey from sporadic 502 errors during every deployment to achieving true zero-downtime updates, including the production-tested patterns, gotchas, and monitoring strategies that make it all work reliably at scale.</p>https://support.tools/kubernetes-liveness-probe-saves-the-day/Wed, 11 Sep 2024 19:26:00 -0500https://support.tools/kubernetes-liveness-probe-saves-the-day/<p>In the world of Kubernetes, keeping your applications running smoothly is critical. One of the key features that can help you achieve this is the <strong>liveness probe</strong>, a powerful mechanism that ensures Kubernetes automatically restarts unhealthy containers. In this post, we’ll explore how Kubernetes liveness probes can save the day by ensuring application stability.</p>
