How can I get "mirrored from" on a GitHub repo?

  • 772

I noticed that https://github.com/apache/ant says "mirrored from git://git.apache.org/ant.git" (with a link) and I'd like to do the same.

https://exyr.org/2011/git-mirrors/ seems like a good write up of the general technique (basically a cron job), but I'm getting some odd errors and I don't see "mirrored from" at https://github.com/pdurbin/openscholar (the destinatation). I'd like the source for the mirror to be https://github.com/openscholar/openscholar

Here is the (trimmed) output I'm seeing:

murphy:tmp pdurbin$ git clone --mirror https://github.com/openscholar/openscholar.git

  1. Regarding the error messages in your output:

    You may want to exclude pull request refs from your mirror. I've recently had a similar issue but the other way round (GitHub as source instead of target), but it looks like it might be related:

    I believe ceejayoz was right in the comment about GitHub staff needing to help. They suggested simply setting up a placeholder, which I did at https://github.com/iqss/openscholar

    It doesn't have the "mirrored from" I was originally looking for, but we can live without it.
