+# Github to Gitlab mirror repository in PHP
+
+The idea here is to mirror the repository using crontab every minute.
+- As you all know about [Gitlab Mirror Issue](https://gitlab.com/gitlab-com/support-forum/-/issues/5331). 
+- Now in new premium update gitlab had stopped the mirroring of external repository making it's a [premium feature](https://about.gitlab.com/releases/2020/03/12/free-period-for-cicd-external-repositories/), so this is a replication of that feature.
+
+## Installation
+
+Just make sure you have self hosted server or local linux environment.
+
+Also make sure you have Github and Gitlab ssh installed.
+
+* ##### Set `crontab -e`
+
+```bash
+* * * * * sh /path/to/mirror.sh >/dev/null 2>&1
+```
+* Edit mirror.php and set appropriate git ssh config for repository on line number 19 and 22
+
+## Any cause of failure on self-hosted server:
+ 
+ - The public ssh key of www-data should have read and write access to source repository.
+ - If the SSH server is not trusted the connection will fail.
+ - To avoid non trusted connection to server, run `ssh -T [email protected]` and `ssh -T [email protected]` at least once to get its fingerprint into the local SSH configuration or hosted server ssh configuration.
+
+* More info on duplicating the repository [Duplicating Repository](https://help.github.com/en/github/creating-cloning-and-archiving-repositories/duplicating-a-repository)
