NGINX in Kubernetes powers routing, security & scalability.
🔹 Ingress Controller → external traffic & TLS
🔹 Reverse Proxy → API routing & caching
🔹 Web Server → static & frontend hosting
Flow: User → LB → NGINX → Services → Pods

Kubernetes Volumes – Quick Ref 🚀

Ephemeral: emptyDir, configMap, secret, projected, downwardAPI
Persistent: PVC, local, NFS
Modern standard: CSI (Ceph, iSCSI, FC)

Use PVC + CSI for prod storage 💾

🔹 Kubernetes DaemonSet
Ensures 1 Pod per node, tracks Pods (selector auto-inferred), and defines Pod spec (template labels & containers).
Perfect for node-level services like logging & monitoring.

🔐 Kubernetes Secret Types (Quick)

Opaque | TLS | dockerconfigjson | basic-auth | ssh-auth | service-account-token
⚠️ dockercfg = deprecated

📌 Prefer dockerconfigjson and let Kubernetes manage service account tokens.

Draining a Kubernetes node does NOT shut down everything.

kubectl drain evicts app workloads and reschedules them safely.
Infra agents like DaemonSets, CNI, CSI, and static pods keep running.
Drain protects apps, not clusters.
