How to create mirrored repositories and keep it synced?

To mirror the existing git repository (i.e, src-repo) into another git repository (i.e., dest-repo), follow the steps given below:

1. Create a bash file and name it as mirror-sync-repo.sh
2. Copy the below code and paste it in your bash file



#!/usr/bin/bash
SourceRepositoryURL=http://src-repo.gitserver1.domain
DestinationRepositoryURL=http://dest-repo.gitserver2.domain
SourceRepositoryDir=src-repo.git
if [ ! -d $SourceRepositoryDir ] 
then
	git clone --mirror $SourceRepositoryURL
	cd $SourceRepositoryDir
	git remote add --mirror=fetch secondary $DestinationRepositoryURL
	cd ..
fi
cd $SourceRepositoryDir
git fetch origin
git push secondary --all



3. Modify the code by replacing pseudocode with the actual repository names and links
4. Save the bash file
5. Open the Terminal app and go to that folder where this bash file is present
6. Execute the bash file on Terminal using sh mirror-sync-repo.sh command, you'll be asked to enter the username and password for both the repositories; just enter that and let it proceed
7. One the execution is finished, both the repositories are mirrored and synced
