Hi @sky-big,

Could you please provide the full information?

Environment

• operator-sdk version:Insert the output of operator-sdk version here
• go version: Insert the output of go version here
• Kubernetes version information: Insert the output of kubectl versionhere
• Kubernetes cluster kind:
• Are you writing your operator in ansible, helm, or go?

This isn't even talking to kubernetes yet

Hi @sky-big,

Could you please let us know if you are following the quick start? Have you already change the specs of any type in the project before run this command? If yes, could you share snaps of the code?

[joelanford]

@sky-big This is typically an issue with the fields added to your structs in _types.go files. Are there any interfaces in the hierarchy of your struct types? If so, those are the likely culprits. They will likely need to be removed or replaced with concrete implementations.

This is all I have to do, I failed in step 2, I haven't modified the *_types.go file yet @joelanford

I failed the second step by following quick start @camilamacedo86

[camilamacedo86]

Hi @sky-big,

As @joelanford explained this error usually occurs because of wrong definitions in the _types files where you define the specs. Also, it is essential to highlight that these steps are fully tested and ensured automatically via the CI; besides, also, I am unable to reproduce your scenario manually. In this way, it shows that you have some issue with the scaffolded project and/or local env setup.

So, in order to help you with. Let's do it step by step and re-check/re-config all OK following my recommendation and suggestions.

1. Remove all and start from the scratch
2. Clean your $GOPATH/bin ( to re-install SDK and its modules )
3. Clean you go cache as described here
4. Re-install the SDK

Tips:

• Ensure that you have NOT more than one go version installed. Keep just the go 1.13+ (Golang do not work well with many versions instaled )
• Ensure that the GOROOT and GOPROXY are setups properly. ( you can check it by running go env. The GOPROXY should be GOPROXY="https://proxy.golang.org,direct" as the GOROOT should point to the go installation. E.g GOROOT="/usr/local/go" )
• Ensure that you have installed SDK and its pre-requirements. ( run operator-sdk version to check if it is installed and its version )
• Ensure that you are following the steps exacly as described in the doc. After each command executed, check its output to be sure that it was finished successfully.

Recommendations:

Also, if you are Getting Started with SDK and Go projects, I'd recommend you follow up the Getting Started instead of the Quick Started since it will provide a better context and example. And then, check the blog post Getting started with Golang Operators by using Operator SDK to have a further understatement over the example done in the Getting Started guide.

Please, let us know if it makes sense and if you could solve the issue with the information provided.

@camilamacedo86 For what it's worth, I'm hitting the exact same situation as @sky-big, despite following the documentation (both Quick Start and Getting Started). I'm on Ubuntu 19.10, but otherwise it's exactly as @sky-big describes.

[joelanford]

I'm not able to reproduce this either. We've seen issues with the code generators because they can sometimes rely on some Go environment variables being set, which are not usually necessary to set in normal Go installations (see #2426)

Can you run the following command and retry:

unset GOROOT
export GOROOT=$(go env GOROOT)

[christophermaier]

That actually worked! Thanks!
