Quick takeaways
- The interaction between Kubernetes and Go can lead to OOMKilled errors due to Go's garbage collector not accounting for memory limits.
- A systematic debugging approach is essential in resolving Kubernetes issues, emphasizing the importance of monitoring and optimizing resource allocation.

Understanding Kubernetes and Go Interaction
A key insight from the discussion revolves around the interaction between Kubernetes and the Go programming language, particularly regarding memory management. The issues arose when a 502 bad gateway error was encountered in a specific production environment, linked to a 502 bad gateway error returned from an API service. This was traced back to an out-of-memory (OOM) issue, highlighting that Go's garbage collector was not aware of the memory limits set by Kubernetes. As a result, Go's heap size continued to grow until it exceeded the container's allocated memory, showcasing the importance of understanding resource management within containerized applications.
