Repository mirroring is a feature in Code Studio. With this feature, you can synchronize your Code Studio git repository with an external repository managed by another git provider.

Similar to any mirroring activity, a repository can be mirrored in two directions:

• Mirroring code out from Code Studio in to another provider
• Mirroring code in to Code Studio from another provider

Mirroring Code Studio out to another repository

This method of mirroring Code Studio out to another repository is also called a “push.”

To set up mirroring Code Studio out to another repository:

1. Log in to your target repository.

   This is the target repository where you will mirror your Code Studio project.

2. Generate an access token.

   You will later use this token instead of your password.

3. Make a note of the repository URL.
4. Log in to Code Studio and access your project.
5. In the left navigation, click Settings > Repository.
6. Click Expand next to Mirroring repositories to expand the section.
7. Fill in the required information, including:
   • In the Git repository URL, enter the URL where Code Studio will push.
   • In Authentication method, select Password.
   • In Password, enter the token that you generated in Step 2.

8. Click Mirror repository.

   Verify that the Mirrored repositories table displays your repository.

Repository mirroring is now configured. Any commits made into your Code Studio repository are now automatically mirrored or pushed out to your external repository.

For a complete tutorial on this configuration, see Code Studio: Repository Mirroring.

Mirroring another repository in to Code Studio

The following is an example for mirroring a Bitbucket repository into Code Studio. This methodology can be adapted for use with most git and CI/CD providers.

After you set up your Code Studio account and configure your workflow, complete the following instructions to set up repository mirroring with BitBucket:

1. In Bitbucket:
   1. Create and commit a bitbucket-pipelines.yml file.

   2. Push the yml file to Bitbucket.

      This runs the pipeline and fails.

   3. In the Bitbucket user interface, go to your repository and click Settings.
   4. In the Pipelines section, click SSH keys.
   5. Generate a new SSH key or upload your own SSH key.
   6. Copy the resulting public key to your clipboard.
   7. In the Known Hosts section on the same page, enter gitcode.acquia.com.
   8. Click Fetch and then add host.
2. In Code Studio:
   1. Log in to the Code Studio user interface or the link provided upon creation in the Cloud IDE.
   2. Navigate to the respective Code Studio project.
   3. Click Settings > Repository > .

Any subsequent commits and creation/deletion of a branch are mirrored to Code Studio.
