gethostbyname Caching in Kubernetes

This repo outlines several approaches to implement caching for the gethostbyname function within Kubernetes environments.

Approaches

First Approach

  • Description: Wrap the gethostbyname function with caching behavior by utilizing a library that is preloaded inside a container via LD_PRELOAD.

Second Approach

  • Description: Implement a global DNS cache. Inside the container, a library preloaded with LD_PRELOAD facilitates communication with the global DNS cache through a Unix socket.
