Syncing Gitlab Code to Github

Background

The company’s code has always been on the internal Gitlab,

including daily code commits, code reviews, project management, personnel management, etc.

Now there is a new business that needs to be deployed on AWS overseas,

which means we need to pull code from the internal Gitlab on Alibaba Cloud to AWS overseas.

Common solutions:

Option 1 is unnecessary — too expensive.

Between options 2 and 3, option 3 is obviously preferred.

Daily code management and personnel management still stay on the internal Gitlab.

Use Gitlab’s mirroring feature to automatically sync code to Github.

AWS pulls code from Github.

First, create a new account on Github, e.g., xx-robot.

If the project to sync is the internal Gitlab’s test project,

then create a corresponding test project under this Github account.

Go to Gitlab - test project - Settings - Repository - Mirroring repositories to configure,

Note the Github authentication method here.

Since Github has disabled pulling code with personal username + password,

you need to use Github’s personal access token instead.

In Github Settings, select Developer Settings

Then select Generate token under Personal Access Tokens

Enter any name for the note,

choose the expiration time based on your needs — here we select no expiration,

select permissions based on your needs — here we select all,

Copy the generated token,

Using the token copied above, along with the username and repo name, construct a URL as follows:

https://${token}@github.com/${username}/${reponame}.git

Enter the constructed URL into the mirror repository field,

leave the password empty,

you can choose to mirror only protected branches,

At this point, the Gitlab to Github sync is complete, as shown below:

You can click the refresh button on the right to trigger a sync,

or any subsequent push to a protected branch will automatically trigger a sync.
