cert-issuer failed while building docker image

[luiszaelot]

I followed cert-issuer guide to build my docker image but it fails with this error message:

I tryed to fix it adding libxml to alpine and python requirements.txt but it does not solve the issue.

Thanks!!

Sorry, finally I fixed the problem. I'll create a pull request to solve this in the master branch.

Here is the patch if someone is getting the same error:

Sorry, I have not permissions to push to this repo. But here is the patch.
Please, validate the patch and add it to master branch.

Bumping into this as well.
