Deconstructing Kubernetes Scheduling

Think of Kubernetes as a super-organized logistics manager. Its job? To ensure every Pod finds the perfect node to live on, based on its requirements, preferences, and constraints.

Let’s dive into how Kubernetes works its scheduling magic. Before we start with that, lets just get a brief idea on how the api server decides which node the application should be deployed into.

When I first saw a Kubernetes deployment, I was hit with a flurry of questions. Questions that made me feel like I had opened the Matrix. Now, after some much-needed experience (and a few existential crises), I think I can finally answer some of those burning questions.
