Kubernetes, the core mental model
Este texto está en inglés.
Kubernetes is a CRUD with a loop. Every object below is a resource in an API you create, read, update and delete, and controllers keep looping until what runs matches what you stored.
The core mental model is literally:
- Pod → a thing that runs
- Node → where the thing runs
- Namespace → which room the thing lives in
- Deployment → keeps the thing running
- StatefulSet → keeps the thing running with identity
- Service → how you reach the thing
- Ingress → how the world reaches the thing
- ConfigMap/Secret → values you shove into the thing
- PV/PVC → where the thing writes stuff
- RBAC → who can touch the thing
- CNI → how the thing talks to other things
