Sometimes, we have a requirement which needs to sync one git repo to another location whenever there is a change in primary repo.

Sync the repo from primary to secondary

git clone --mirror https://primary_repo_url/primary.git

cd primary.git

git remote add --mirror=fetch secondary https://secondary_repo_url/secondary.git

git fetch origin

git push secondary --all
git push secondary --tags

Sync it automatically

To achieve this, we can set up a Job in Jenkins or Teamcity to monitor if any commit in primary repo, and then run script below

git fetch origin
git push secondary --all
git push secondary --tags
