Thanks @qinguoyi for the help, let me take a try first.

[kerthcet]

Is this change related? If not, we can have another PR to cover your case.

[qinguoyi]

when i execute the cmd "make helm", this is auto generated. i revert this

[kerthcet]

Let's rename this to namespace intuitively. Same to other places, secret is just one of the resources in the namespace I think.

[qinguoyi]

ok, i update this soon.

[kerthcet]

Please don't, let's make sure this variables only available in main function for now.

[qinguoyi]

ok ,i revert this soon.

[qinguoyi]

as suggested, i re-push the code. @kerthcet

Thanks @qinguoyi this makes sense to me. But we have some confusions on the document right now because we have two different ways to install lws, one with kustomize, another with helm chart, I'll update the document later to make sure people can participate in the project development easier. Thanks anyway.
