A Release Is an Installed Chart is a free Helm Academy lesson on CoddyKit — lesson 2 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Helm Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
From Chart to Release
When you install a chart into a cluster, Helm creates a release: one running instance of that chart with a name you choose. 🚀
The Install Command
You make a release with helm install. The first argument is the release name, the second is the chart to deploy.
helm install my-web ./mychartChart Is the Blueprint
Think of the chart as a blueprint and the release as the house built from it. Many releases can come from one chart.
Release Names Are Unique
Each release name must be unique within its namespace. That name is how you later upgrade, inspect, or uninstall it.
Releases Live in a Namespace
A release belongs to one Kubernetes namespace. The same release name can be reused in a different namespace without clashing.
helm install my-web ./mychart -n stagingListing Your Releases
Run helm list to see the releases in your current namespace, each with its chart, revision, and status.
helm listState Stored in the Cluster
Helm 3 stores each release's data in a Kubernetes Secret inside the namespace. No external server is needed to track it.
Checking One Release
Use helm status with the release name to see its current state and the rendered notes for that running instance.
helm status my-webReleases Carry Their Config
A release remembers the values you supplied at install. Helm uses them again on upgrade unless you override them.
Removing a Release
When you no longer need it, helm uninstall deletes the release and the cluster resources it created.
helm uninstall my-webWhy the Distinction Matters
Separating chart from release lets you manage each deployment independently, even when they share the same underlying chart. 🎯

Recap
Installing a chart creates a release: a uniquely named instance in a namespace that you can list, upgrade, and uninstall. ✅
