Discover how a seemingly simple 502 error in Kubernetes can uncover complex interactions between Go and containerized environments.

Emin Laletović, a solution architect at Hybird Technologies, shares his experience debugging a production issue in which a specific API endpoint failed due to out-of-memory errors.

He walks through the systematic investigation process, from initial log checks to uncovering the root cause in Go's memory management within Kubernetes.

You will learn:

• How Go's garbage collector interacts with Kubernetes resource limits, potentially leading to unexpected OOMKilled errors.

• The importance of the GOMEMLIMIT environment variable in Go 1.19+ for managing memory usage in containerized environments.

• Debugging techniques for memory-related issues in Kubernetes, including GODEBUG for garbage collector tracing.

• Considerations for optimizing Go applications in Kubernetes, balancing performance and resource utilization.
