Support authentication for private nexus repo

[rockerhieu]

I couldn't find a way to use badge for a private nexus repo which requires authentication.

Please troubleshoot. Thanks!

Happy to support this. It looks like this will require two things: (1) a small modification to server.js to read the nexus secret from serverSecrets if it exists, and (2) self-hosting an instance of Shields. If you are able to work on that, or if anyone else reading this wants this feature, and you need help moving that forward, feel free to ask here and one of the maintainers can help.

Hey @paulmelnikow, let me know the next steps. I'm ready to move forward.

Great!

You could take a look at the Jira badge, which pulls the secret value from serverSecrets. You could add code to the Nexus section, also in server.js, to do something similar. You can test it out locally using your authorization information, and open a pull request with the change.

You could also add a test that uses a mock to show that the authorization information is passed to the API as expected, though that might be more effort than it's worth. This is the test code:
