Sonarcloud fails to analyze Github Pull Request when Github IP Restrictions are in place

Overview

Sonarcloud fails with a 500 error when analyzing a pull request against a repository in a Github organization with IP restrictions. Github has a “allow-ip-addresses-of-github-apps” feature to allow apps to bypass IP restrictions but it does not appear that sonarcloud utilizes this. Also there does not appear to be a published list of static IP addresses which could be whitelisted manually.

I am encountering this issue when using the dotnet sonarscanner utility, but it also affects our projects that are directly analyzed from github (no CI system).

Is there any way to get sonarcloud.io to work with a github organization that has IP restrictions enabled?

  • Steps to reproduce

    • Enable IP restrictions in your Github organization.
    • Create a pull request in one of your GH repos.
    • Call the sonarscanner to scan the pull request.
  • Potential workaround

Hi @kthompso,

Welcome to the community forum, and thanks for posting your feedback.

By design, IP addresses used by :sonarcloud: 's enpoints are recycled and rotate over time. Hence allowing static IPs is not a solution that you could use from GitHub or elsewhere.

@AlxO

Thank you for the reply @AlxO . Do you know if there are any plans to get sonarcloud to work with GH IP restrictions in the future?

Hi @kthompso , not to my knowledge.
I will however make sure your need is captured.
