π Just deployed my first app on AWS EKS! From kubectl confusion to pod perfection - the learning curve was real but SO worth it. Container orchestration finally clicked! π‘ #publiclearning #EKS #kubernetes #aws #devops #firstdeployment.

π EKS + Fargate = serverless Kubernetes! No EC2 instances to manage, pay only for pods, automatic scaling. The future of container deployment is here. #EKSFargate #Serverless #Kubernetes #AWS.

Just deployed to production on a Friday afternoon. My weekend plans? Sitting by my laptop like a worried parent waiting for their teenager to come home. #DevOps #FridayDeploy #ProductionLife #TechHumor.

EKS giving you headaches? π€ 9 out of 10 issues are: missing IAM roles, CoreDNS hiccups, or forgetting the Load Balancer Controller π― Pro tip: Check your IRSA setup first! #EKS #Kubernetes #DevOps #Troubleshooting.

Remember when deploying Kubernetes meant sleepless nights? π΄ Amazon EKS said "hold my coffee" β Now you get enterprise-grade K8s without the chaos. Deploy faster, sleep better π€ #EKS #CloudNative #DevLife.

π Finally cracked it! My first MERN app monitoring with Prometheus + Grafana is LIVE!. Fix? Same K8s namespace + simple DNS names vs FQDN. Simple wins!. #DevOps #Kubernetes #Prometheus #Grafana #MERN #Monitoring.

π€ Still fighting Prometheus "context deadline exceeded" errors! Backend /metrics works fine when tested directly, but Prometheus won't scrape it. Even moved to same namespace - no luck! π€¬ #Kubernetes #Prometheus #DevOpsStruggles.

Debugging π β Prometheus shows context deadline exceeded when scraping backend. Looks like a service DNS or selector mismatch in K8s. Working on fixing pod-to-service communication. #PublicLearning #Kubernetes #DevLife.

π₯ EKS Pro Tip: Use Fargate for serverless pods!.No more managing EC2 nodes or scaling headaches. Just deploy and AWS handles infrastructure. eksctl create cluster --fargate.Pay only for what you use! π°.#AWS #EKS #Serverless.

π TIL: Creating an EKS cluster is super easy with eksctl!.Just run: eksctl create cluster --name my-cluster --region us-west-2.That's it! No complex configs. eksctl handles VPC, subnets & worker nodes automagically β¨.#AWS #EKS #Kubernetes.

π TIL: ArgoCD just changed my entire deployment game!.From manual kubectl nightmares to GitOps heaven in one day. Why did nobody tell me declarative deployments could be this smooth? π€―.Drop your biggest DevOps game-changer below π.#ArgoCD #GitOps #DevOps #Kubernetes #TIL.

π Just dove into Grafana + Prometheus and WOW! π.Going from "Is my app even running?" to beautiful real-time dashboards that actually tell you WHY things broke π₯.Learning curve? Steep but SO worth it. Your future 3AM self will thank you π.#DevOps #Monitoring.

π€― Mind = BLOWN! Just discovered Helm for Kubernetes and I feel like I've been doing deployments the hard way this whole time π
.Think of it as npm for K8s - one command replaces 20+ YAML files!.Who else wishes they learned this sooner? πββοΈ.#Kubernetes #DevOps #Helm.

Just mastered Role-Based Access Control (RBAC) in Kubernetes! π Finally understand how to properly secure cluster resources with roles, bindings, and service accounts. Game-changer for production deployments! #Kubernetes #DevOps #RBAC.

Today I learned horizontal vs vertical scaling in Kubernetes! π.π Horizontal = more pods (scale out).π Vertical = more resources per pod (scale up).K8s HPA and VPA make it seamless! πͺ.#Kubernetes #DevOps #CloudNative.

Shoutout to for the solution! . Sometimes the fix is simpler than you think - just use current versions. The K8s ecosystem evolves rapidly and compatibility matters. Onward to learning more container orchestration! π. #kubernetes #debugging #devops.
