🧬 Pod Anatomy
Kaun pod banata · kaun andar · kaun bahar · kaun node
Kubernetes ki har cheez in 4 buckets me se ek hai. Neeche naksha — kisi bhi chip pe click karo, upar detail khulega. Rang se bucket pehchano. Ek baar baith gaya, to poora K8s ka map dimaag me. 🗺️
🟢 POD BANATA
🔵 POD KE ANDAR
🟠 POD KE BAHAR (rule)
🟣 NODE-LEVEL
👆 Kisi chip pe click karo
Har chip batayega: wo kya hai, kis bucket me, aur ek line me kaam.
🧠 Control plane — decide/store karta (khud "kaam" nahi karta)
Ye POD BANATE hain ↓
Ye POD NAHI — sirf rules/config (etcd me records) ↓
⬇ workloads se POD banta, jo node pe chalta ⬇
🟣 NODE — ek machine (EC2/VM) jaha pods chalte
Node ka apna software (pod nahi) ↓
🔵 POD — yaha app chalta
Pod ke andar containers ↓
Pod ki settings (container pe lagti) ↓
🎯 Ek line: workloads (Deployment/StatefulSet/DaemonSet/Job/CronJob) pod banate → pod ke andar container (init/main/sidecar) kaam karta → Service/ConfigMap/Ingress/NetworkPolicy bahar rules (pod nahi) → sab node pe chalta, jise kubelet manage karta.
