Helm allows you to package all Kubernetes resources into a single unit called a Helm Chart. Instead of managing multiple manifest files, you work with templates and values files. Helm automatically handles resource creation order and communicates with the Kubernetes API server. ### What you will learn in this video: - What is Helm in Kubernetes - What is a Helm Chart - Why Helm is better than kubectl apply - How Helm install, upgrade, and rollback work - How Helm maintains release history - How to use public Helm charts ### Helm commands explained: helm install my-app ./chart helm upgrade my-app ./chart helm list helm rollback my-app 1 ### Real-world use case: To set up Kubernetes monitoring, you typically need: - Prometheus (metrics collection) - Grafana (visualization) - Alertmanager (alerts) - Loki (log aggregation) - Jaeger / Tempo (distributed tracing) Setting this up manually requires creating many Kubernetes resources. Using public Helm charts, the entire stack can be installed with a single command. This video is perfect for: - Kubernetes beginners - DevOps engineers - Anyone struggling with kubectl apply and rollback issues Watch till the end for a clear hands-on explanation.
