Bug Report

When following the steps for the Quickstart, the second step (operator-sdk create api) fails

What did you do?

I just followed the steps described in the quickstart

mkdir memcached-operator
cd memcached-operator
operator-sdk init --domain example.com --repo github.com/example/memcached-operator
operator-sdk create api --group cache --version v1alpha1 --kind Memcached --resource --controller

What did you expect to see?

A project ready for the next step, ie"make docker-build docker-push"

What did you see instead? Under which circumstances?

operator-sdk create api --group cache --version v1alpha1 --kind Memcached --resource --controller
Writing scaffold for you to edit...

The go1.16.2 is not supported yet. This issue will not be faced if you use the go version >= 1.15+ <1.6 which is the current version supported. To start to support 1.16 we need it be supported in the other projects first such as k8s, controller-runtime and kubebuilder to say a few.

This need is tracked already see: kubernetes-sigs/kubebuilder#2067

However, so far we would like to recommend you use go 1.15.

I am closing this one as sorted out. Thank you for your collaboration.

Thanks for the quick/clear answer.
As a suggestion, it would be interesting for newbies like me to explicity mention that go versions higher than v1.15 are currently not supported on the installation guide page
