🔗 Prerequisite: Chapter 02 (Scheduling, affinity, taints) — ✅ you’ve mastered it!

Phase 1: Deployment Fundamentals

Learn what a Deployment is and how to create one.

1. deployment-one.yml

   → Your first basic Deployment (replicas, pod template, labels).

2. imperative-deployment.sh

   → Create Deployment via kubectl create deployment (CLI vs YAML).

3. declarative-deployment.yaml

   → Full declarative YAML (best practice for GitOps).

Phase 2: Deployment Strategies & Updates

Control how updates roll out (rolling update, recreate, canary).

1. deployment-with-strategy

   → Customize update strategy (RollingUpdate vs Recreate), maxSurge, maxUnavailable.

2. deployment-different

   → Likely shows different update scenarios (e.g., image change, env update).

Phase 3: Advanced Scheduling in Deployments

Apply Chapter 02 concepts to Deployments (affinity, anti-affinity).

1. deployment-using-affinity.yaml

   → Node affinity in Deployment (e.g., prefer SSD nodes).

2. deployment-with-anti-affinity.yaml

   → Pod anti-affinity to spread replicas across nodes (critical for HA!).

Phase 4: Services & Networking

Expose Deployments internally/externally.
