Helm install unknown flag --name

问题

When I try to install a chart with helm:

helm install stable/nginx-ingress --name my-nginx

I get the error:

Error: unknown flag: --name

But I see the above command format in many documentations.

Version:

version.BuildInfo{Version:"v3.0.0-beta.3", GitCommit:"5cb923eecbe80d1ad76399aee234717c11931d9a", GitTreeState:"clean", GoVersion:"go1.12.9"}

Platform: Windows 10 64

What could be the reason?

回答1:

In Helm v3, the release name is now mandatory as part of the commmand, see helm install --help:

Usage:
helm install [NAME] [CHART] [flags]

Your command should be:

helm install my-nginx stable/nginx-ingress

---

Furthermore, Helm will not auto-generate names for releases anymore. If you want the "old behavior", you can use the --generate-name flag. e.g:

helm install --generate-name stable/nginx-ingress

The v3 docs are available at https://v3.helm.sh/docs/, but as it is a beta version, the docs will not be accurate for a while. It's better to rely on the CLI --help, that is auto-generated by Go/Cobra.

回答2:

The --name flag is no more in version 3.

It should be

helm install my-nginx stable/nginx-ingress

Syntax:

help install [name] [chart]
