helm error "Error: This command needs 2 arguments: release name, chart path"

I am getting an error in my kubernetes cluster while upgrading my install of kamus

$ helm --debug upgrade --install soluto/kamus

[debug] Created tunnel using local port: '64252'
[debug] SERVER: "127.0.0.1:64252"
Error: This command needs 2 arguments: release name, chart path

Using helm version 2.13.1

This error is also known to be cause by not correctly using --set correctly or as intended.

As an example when upgrading my ingress-nginx/ingress-nginx installing as such:

 --set "controller.service.annotations.service\.beta\.kubernetes\.io/azure-load-balancer-health-probe-request-path"=/healthz,"controller.service.annotations.service\.beta\.kubernetes\.io/azure-dns-label-name"=$DNS_LABEL

This caused the same error as listed above.

When I removed the quotations it worked as intended.

 --set controller.service.annotations.service\.beta\.kubernetes\.io/azure-load-balancer-health-probe-request-path=/healthz,controller.service.annotations.service\.beta\.kubernetes\.io/azure-dns-label-name=$DNS_LABEL

The error in this case had nothing to do with not correctly setting a release name and or chart. More explanation of --set issues and solutions are below.

Solution

  • Helm upgrade command requires release name and chart path. In your case, you missed release name.

    helm upgrade [RELEASE] [CHART] [flags]

    helm --debug upgrade --install kamus soluto/kamus should work.
