Helm
ELI5 — The Vibe Check
Helm is the package manager for Kubernetes — like npm but for deploying apps to your cluster. Instead of writing a dozen complicated YAML files from scratch, you grab a pre-built Helm chart (package) for something like PostgreSQL or Redis and deploy it with one command. Huge time saver.
Real Talk
Helm is a package manager for Kubernetes that uses 'charts' — packages of pre-configured Kubernetes resources. Charts are templated YAML configurations that can be customized via values files. Helm also manages release history, enabling easy upgrades and rollbacks of Kubernetes deployments.
Show Me The Code
# Install a chart
helm install my-postgres bitnami/postgresql
# Upgrade a release
helm upgrade my-postgres bitnami/postgresql --set auth.password=newpass
# Rollback to previous version
helm rollback my-postgres 1
