Frequent usage causes rate limit errors

[adamdecaf]

Thanks for the handy Action to run on projects. We've found it useful in several projects.

There's an issue we've ran into when opening PR's during normal working hours. After looking at the script I can see there are 8 wget calls to github services, which can pretty easily exceed the limit of 60/hour from a single IP address.

Would y'all be open to using secrets.GITHUB_TOKEN (I think this would work) and better management of the wget calls in the script?

This is an issue for us aswell. We are using matrix in our github actions to scan the different folders, because otherwise it will always fail to comments as it reports that the issue is not part of this PR.

So as we invoke this in matrix, we run the action multiple times (16 in our case), which then exceeds the rate limit. And as the API calls are part of the entrypoint, we have no way of using user/app tokens to properly authenticate and bypass this limitation in the current state.

Hey @adamdecaf - I'm not sure I follow, GITHUB_TOKEN is required for this action already.

I'm likely being dim, could you help me understand your ask?

Those wget calls are running in regular anonymous mode, where they are subject to rate-limiting rules. If we change these to use the GITHUB_TOKEN, GitHub will see them as trusted, thus easing the rate-limiting rules. Iirc this can be done with a query string parameter and/or some HTTP request header.

While at it, may I suggest getting all required files in at build time instead? this would speed up execution and decouple the runtime image from these additional binaries.
Having the logic only do these downloads if INPUT_COMMENTER_VERSION or INPUT_TFSEC_VERSION are defined (and not set to latest). Wdyt?

[owenrumney]

I used to build the action with the binaries already baked in but then being able to switch out the version of tfsec was requested.

I think maybe it is the lesser of two evils to get everything in place at build time, I'll look to chain the build of the action from the back of a new release of tfsec and synchronise the versions in the process..... sounds like a fun friday task

This is exactly right. It's a large difference from anonymous to trusted rate limits. You can set it in an HTTP header.

This branch wasn't working, but the idea is here: adamdecaf@20567c7

I am running the same issue inpulling image from dockerhub. Rate limited. IS it possible to pass the default image name? change the location of "alpine" image?

We are running on self-hosted gh-runner on kubernetes with ephemeral runners.

@iaacautomation as a workaround I'm doing this: https://github.com/aquasecurity/tfsec-pr-commenter-action/pull/59/files

I think this is fixed in the latest release 1.3.0 by #82
