Helm

In simple English

In Kubernetes environments, deploying applications manually requires writing and managing multiple YAML configuration files, which becomes complex and error-prone. Helm solves this problem by packaging these configurations into reusable units called charts. A Helm chart is essentially a collection of files that describe a set of Kubernetes resources needed to run an application. Helm allows teams to version these packages, manage dependencies, and deploy applications consistently across different environments. Teams use Helm to manage their infrastructure as code, making deployments faster, more reliable, and easier to reproduce. When engineers say they are using Helm, they typically mean they are leveraging these pre-built charts to deploy services rather than manually creating configuration files.

Learn about Helm, the Kubernetes package manager used for deploying and managing containerized applications.

Say it like this

✓We deployed the application using Helm charts.
✓Let me check the Helm values before deploying.
✓This microservice needs a custom Helm chart.

Real examples

in a standup

"We created a new Helm chart for the payment service so other teams can deploy it easily."

in a code review

"The Helm chart templates need to be updated to support the new environment variables."

in a team meeting

"Using Helm reduced our deployment time from 30 minutes to 5 minutes across all clusters."

Don't say this

Handle with care. Helm is a specific Kubernetes package manager—do not confuse it with general steering or leadership metaphors, or with other container orchestration tools.

✕We need to Helm our application now.
✓We need to deploy our application using Helm now.— Helm is a noun (a tool) and package manager, not a verb. You deploy with Helm, but do not use Helm as a verb directly.
✕Helm is a container orchestration platform.
✓Helm is a package manager for Kubernetes, which is a container orchestration platform.— Helm is a tool that works on top of Kubernetes, not a replacement for it or an orchestration platform itself.
✕I will write a Helm configuration instead of a Helm chart.
✓I will create a Helm chart for this application.— The correct term is Helm chart, not Helm configuration. Charts contain templates, values, and metadata.
