Mirroring from Gitlab to Github

Question

I have been using a private Gitlab instance to hold all my code. But since most of the staff that work with me now have a Github account, i would really like to get moving and mirror my Gitlab repo to Github.

My situation:

• a server running Gitlab (Omnibus)
• a Github account for which I'll create an organization for where me and my staff can be organized together.

I know that there is the --mirror switch in git, but I am not really sure how this is ment to work. Documentation I found online was very wonky... So it would be nice if someone could help me out. :)

Answer 1

GitLab has now an option to do this from the UI, go to the Settings->Repository of your repo:

https://gitlab.com/yourUserNameInGitLab/yourRepoName/settings/repository

Then find the option "Mirror a repository" and click on expand. What you want to do is choose the "Push" mirror direction and fill this URL:

https://[email protected]/yourUserNameInGitHub/yourRepoName.git

In the password field, you have to use a Personal Access Token (as GitHub has deprecated password access now), which you can generate here: https://github.com/settings/tokens (don't forget to enable the "repo" and "workflow" permissions when generating it)

Answer 2

Another options is to add an additional URL to the origin:

git remote set-url --add origin [email protected]:<USERNAME>/<PROJECTNAME>.git 

When you push to origin it will push to both the original origin (gitlab) and the one added above (github).
