How to convert the existing helm chart to a set of Kubernetes manifests?

Question

How can I obtain just a set of Kubernetes yaml files filled in with default Helm chart parameters, so that I can use kubectl apply -f ./manifests to run the required service?

Answer 1

You can use the helm template command:

Render chart templates locally and display the output.

Any values that would normally be looked up or retrieved in-cluster will be faked locally. Additionally, none of the server-side testing of chart validity (e.g. whether an API is supported) is done.

helm template [NAME] [CHART] [flags]

e.g:

helm template my-chart stable/chart --output-dir /home/user/my-chart

Then you can use kubectl apply -f /home/user/my-chart
