What is Helm?
Helm is the package manager for Kubernetes. It uses "charts" — pre-configured Kubernetes resource templates — to define, install, and upgrade applications. Helm manages releases (instances of charts) and supports versioning, rollback, and dependency management.
Key Helm Concepts
- Chart — A package of Kubernetes YAML templates + values. Can come from a repo, a local directory, or a .tgz file.
- Release — An instance of a chart deployed to a cluster. Each install creates a new release.
- Repository — A collection of charts (like Bitnami, Artifact Hub). Added with
helm repo add. - Values — Configuration that customizes a chart. Passed via
-f values.yamlor--set key=value. - Revision — Each install/upgrade creates a new revision. Rollback targets a specific revision number.
Most Used Helm Commands
| Command | Purpose | Example |
|---|---|---|
| install | Deploy a chart | helm install my-app bitnami/nginx |
| upgrade | Upgrade a release | helm upgrade my-app bitnami/nginx |
| uninstall | Remove a release | helm uninstall my-app -n prod |
| rollback | Rollback to revision | helm rollback my-app 1 |
| list | List releases | helm list -A |
| template | Render templates | helm template my-app ./chart |
| repo add | Add a chart repo | helm repo add bitnami https://... |
| show values | View chart values | helm show values bitnami/nginx |
| get manifest | Get deployed YAML | helm get manifest my-app |
| pull | Download chart | helm pull bitnami/nginx --untar |
Helm Workflow
A typical Helm workflow for deploying an application:
helm repo add— Add the chart repositoryhelm search repo— Find the chart you needhelm show values— Check available configuration optionshelm install— Deploy with your custom valueshelm upgrade— Update the release when chart or values changehelm rollback— Revert if something breaks
Values Precedence
Helm merges values in order of precedence (last wins):
- Chart defaults (
values.yamlin the chart) - User-supplied values files (
-f custom.yaml, applied left-to-right) - Inline
--setoverrides (highest priority)
Use --set-string when you need values to be treated as strings (e.g., numeric-looking IDs that shouldn't be converted to numbers).
Privacy First
All command building happens in your browser. Your release names, chart references, values, and cluster details are never sent to any server.
