Mirroring a Repository Locally Using reposync from Depot

This guide provides instructions on synchronizing repositories using reposync.

When syncing repositories, consider the storage requirements. Examples:

• The CIQ Bridge repo is approximately 1.4GB.
• The full CentOS repository can exceed 100GB.

reposync Command

The reposync command creates local copies of remote repositories. It avoids re-downloading packages that are already present in the local directory.

By default, reposync synchronizes all enabled repositories. However, you can customize the set of repositories to be synchronized using standard DNF5 options such as --repo, --enable-repo, or --disable-repo.

Enable reposync

To run reposync on a modern OS such as Rocky Linux 9, or if you plan to sync multiple repositories, you will need to create a separate repo file for each repository. Follow these steps:

1. Create a Repo Configuration File

1. After selecting the repository you want to mirror, navigate to ‘My Products’ and click on the product that contains the repository.

2. In the product view, you’ll see a list of available repositories. Click the “…” to view the repository menu on the right side of the repository name.

3. Click on option ‘DNF Repo Config’.

4. Copy the provided configuration.

5. Open a text editor and create a new file in /etc/yum.repos.d/ with a descriptive name like {depot-repository-name}.repo.

6. Paste the configuration obtain form Depot into the file and save Example:

   [ciq-bridge.x86_64]
   name = CentOS 7.9 CIQ Bridge Updates (x86_64)
   baseurl = https://depot.ciq.com/files/bridge/ciq-bridge.x86_64
   gpgkey = https://ciq.com/keys/rpm-gpg-key-ciq
   username = DEPOT_USER
   password = DEPOT_TOKEN
   metadata_expire = 5
   priority = 50
   repo_gpgcheck = false
   gpgcheck = true
   enabled = true
   skip_if_unavailable = true
   

7. [OPTIONAL] All products in the “My Products” menu will require user name and password. To be able to reposync repositories form those you will need to modify the DNF config file so the baseurl include those. Using the previous example you need to modify baseurl = https://depot.ciq.com/files/bridge/ciq-bridge.x86_64 to become baseurl = https://DEPOT_USER:DEPOT_TOKEN@depot.ciq.com/files/bridge/ciq-bridge.x86_64.

   Example:

   [ciq-bridge.x86_64]
   name = CentOS 7.9 CIQ Bridge Updates (x86_64)
   baseurl = https://DEPOT_USER:DEPOT_TOKEN@depot.ciq.com/files/bridge/ciq-bridge.x86_64
   gpgkey = https://ciq.com/keys/rpm-gpg-key-ciq
   username = DEPOT_USER
   password = DEPOT_TOKEN
   metadata_expire = 5
   priority = 50
   repo_gpgcheck = false
   gpgcheck = true
   enabled = true
   skip_if_unavailable = true
   

2. Run reposync

Once the configuration file is created, use dnf to sync the repository:

dnf reposync --repoid={depot-repository-name} --download-metadata --download-path={destination_path}
