Error: must either provide a name or specify --generate-name

and I am using command like this:

helm install ./traefik-helm-chart --generate-name

and give this tips:

Error: validation: chart.metadata is required

what should I do to fix this?

Answer 1

For anyone else getting to this page by googling the error message (like I did).

I received this same error because my custom chart file was called "chart.yaml" instead of "Chart.yaml" (note the uppercase C)

Answer 2

You need to give the exact path where the Chart.yaml file is located

helm2

helm install --name <release-name> <chart-path>
(e.g., helm install --name prometheus ./prometheus/)

helm3

helm3 install <release-name> <chart-path>
(e.g., helm3 install prometheus .)

helm3 install --generate-name <chart-path>
