Possible Solution

Add operator-sdk as a tool candidate

Context

The operator-sdk CLI is not available as part of any of the default APT/Yum repositories and does not require any special privileges to run. So, it is a good candidate for an arkade tool.

Your Environment

• Operating System and version (e.g. Linux, Windows, MacOS):

  • Amazon Linux
  • Ubuntu
  • MacOS

• What arkade version is this? 0.8.5

Hi @xshyamx thanks for this suggestion, the app sounds fine to me.

For future suggestions, please can you follow the contribution guide and wait for approval before sending PRs? This is to avoid you spending unnecessary time and effort before we have agreement on a change.

The same approach applies to OpenFaaS/k3sup/inlets etc.

Hi @alexellis ,

I'm encountering a special case with operator-sdk where there is no windows binary. There are a couple of options on how to handle it

1. Return empty URL for BinaryTemplate or URLTemplate both will fail with the following error messages

   # empty BinaryTemplate
   Downloading: https://github.com/operator-framework/operator-sdk/releases/download/v1.22.0/
   Error: incorrect status for downloading tool: 404
   
   # empty URLTemplate
   Downloading: 
   Error: Get "": unsupported protocol scheme ""
   

2. Check for empty string from tool.GetURL and throw an error

   dlURL, err := tool.GetURL(os, arch, ver, quiet)
   if err != nil {
   	return "", err
   }
   if dlURL == "" {
   	return "", errors.New("No available download for this environment")
   }
   

   Which results in

   $ ./arkade get --os ming  operator-sdk
   Downloading: operator-sdk
   2022/06/18 13:31:15 Looking up version for operator-sdk
   2022/06/18 13:31:16 Found: v1.22.0
   Error: No available download for this environment
   

I prefer option 2 but, would like your opinion on how to handle it

[alexellis]

I'd say that you should allow then URL to be generated so that it's a valid URL but returns a 404. That's the approach we've taken elsewhere. Try it and see the message that you get.
