https://github.com/operator-framework/operator-sdk/blob/v0.10.x/doc/operator-scope.md fail to succeed

@yueyongyue Support for the --cluster-scoped flag was removed in v0.8.0. See #1434 for the motivation.

However, cluster-scoped CRDs and operators are still supported. Read the operator scope documentation on the changes needed to run a cluster-scoped operator.

@joelanford Use this document, Gets a empty Namespace

@joelanford
the doc is not available anymore,
Is there any other documentation?

[camilamacedo86]

See; https://sdk.operatorframework.io/docs/building-operators/golang/operator-scope/ for the latest release. However, note that you can check the old docs by using the tags. E.g https://github.com/operator-framework/operator-sdk/blob/<release-tag>/doc/operator-scope.md

I followed steps defined in the Doc but it didn't work properly. I get this error from operator:
