Kubernetes Day 11 – Mastering Deployments: Rolling Update, Recreate & Blue-Green Deployment

✅ *What are Kubernetes Deployments?* – Understand the concept of Deployments and how they manage Pods, ReplicaSets, and application updates. ✅ *Deployment Strategies in Kubernetes* – Explore Rolling Update, Recreate, Blue-Green, and Canary strategies, with their pros, cons, and use cases. ✅ *Hands-On with Rolling, Recreate, Blue-Green, and Canary* – Step-by-step demos showing YAML changes, image updates, and traffic shifting. ✅ *Key Takeaways for Real-World Deployments* – Learn how to choose the right deployment strategy for zero downtime, testing, and scaling needs. 🚀 Video Chapters 🚀 Understanding Kubernetes Deployments ➥ 0:00 – Introduction & recap of Kubernetes services (ClusterIP, NodePort, LoadBalancer) ➥ 1:15 – Recap of Kubernetes hierarchy: Pods → ReplicaSets → Services Deployment Strategies Overview ➥ 3:06 – Limitations: No rolling updates, rollback support, or version control Types of Deployments 1. Rolling Update ➥ 6:40 –Rolling Update Create Deployment → ReplicaSet → Pods (v1) → Service (LoadBalancer) Update image to v2: `kubectl set image deployment name container=v2` Observe traffic shift from old to new ReplicaSet gradually 2. Recreate ➥ 30:35 – Recreate Deletes all old Pods before creating new ones Demo: Update strategy `type: Recreate` in YAML 3. Blue-Green Deployment ➥ 40:56 –Blue-Green Deployment Advantage: Pre-deployment testing in Green before traffic switch Cost: Higher (maintains two deployments) Demo: Create Blue Deployment + Service → Test v1 Create Green Deployment (v2) → Update Service selector to Green 4. Canary Deployment ➥ 52:48 – Canary Deployment Demo: Adjust replica counts (`blue: 3`, `green: 1` = 75%/25% split) Key Takeaways ➥ 1:01:15 – Summary: Rolling Update: Default, zero downtime, ReplicaSet-based. Recreate: Simple but causes downtime. Blue-Green: Safer but costly (two deployments). Canary: Gradual traffic shift for testing. ✅ 𝗔𝗹𝗹 𝘁𝗵𝗲 𝗰𝗼𝘂𝗿𝘀𝗲 𝗼𝘂𝘁𝗹𝗶𝗻𝗲 𝗵𝗮𝘀 𝗯𝗲𝗲𝗻 𝘂𝗽𝗹𝗼𝗮𝗱𝗲𝗱 𝘁𝗼 𝗺𝘆 𝗚𝗶𝘁𝗵𝘂𝗯 𝗿𝗲𝗽𝗼𝘀𝗶𝘁𝗼𝗿𝘆: https://github.com/akashkumar975/Terr...
