One Chart, Many Releases
Installing the same chart multiple times side by side.
One Chart, Many Releases is a free Helm Academy lesson on CoddyKit — lesson 4 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.
One Chart, Many Instances
A single chart can power many releases at once. Each install is its own independent instance running side by side. 🔁
Why Reuse a Chart
The same app often runs more than once: a dev copy and a prod copy, or one per customer. One chart serves them all.
Two Releases, Same Chart
Just install the chart twice with different names. Helm treats each as a separate release it can manage on its own.
helm install web-dev ./mychart
helm install web-prod ./mychartDifferent Values Each Time
Give each release its own settings, so the dev instance can run one replica while prod runs five from the very same chart.
helm install web-prod ./mychart --set replicaCount=5Names Keep Them Apart
The release name is the key that separates instances. Helm uses it to know which resources belong to which release.
Names Flow into Resources
Good charts include the release name in resource names so two installs do not collide. The built-in .Release.Name makes this easy.
metadata:
name: {{ .Release.Name }}-webNamespaces as a Boundary
You can also place each release in its own namespace, which keeps the same release name from clashing across environments.
helm install web ./mychart -n team-aIndependent Lifecycles
Each release upgrades, rolls back, and uninstalls on its own. Touching web-dev never affects web-prod.
Seeing Them Together
Run helm list across namespaces to view every instance of the chart at once and compare their revisions.
helm list --all-namespacesA Common Pitfall
If a chart hardcodes resource names instead of using the release name, a second install fails on a name conflict. Templating avoids that.
The Payoff
Write a chart once, then spin up as many tailored releases as you need. That reuse is the core power of Helm. 🎯

Let us confirm how multiple releases coexist.
Recap
One chart can drive many releases, each with its own name, values, and lifecycle. Templated names keep them from colliding. ✅
