Creating a mirror 

If you are maintaining a mirror please join the Mirrors category on discourse.openrobotics.org: https://discourse.openrobotics.org/c/infrastructure-project/infra-mirrors/ for both feedback and prompt updates.

Using a Mirror 

To use a mirror, replace packages.ros.org with the mirror URL in your ros2-latest.list file:

# Example for TUNA mirror
sudo sed -i 's|http://packages.ros.org/ros2/ubuntu|https://mirrors.tuna.tsinghua.edu.cn/ros2/ubuntu|g' /etc/apt/sources.list.d/ros2-latest.list
sudo apt update

Setting up a Mirror 

The ROS infrastructure uses rsync to distribute packages. To create a local mirror of the ROS 2 repositories:

Storage Requirement: Ensure you have at least 500GB of available disk space.
Sync Command: Use rsync to pull from the official OSUOSL endpoints:

# Sync the main ROS 2 repository
rsync -azv rsync.osuosl.org::ros2-main /your/local/path --delete

Maintenance: Set up a cron job to sync every 6-12 hours.

Adding your mirror to this list 

To be officially listed, your mirror must meet the following requirements:

Support HTTPS.
Sync at least once every 24 hours.
Provide a contact email for infrastructure alerts.

Once verified, please open a Pull Request against this page or post in the Mirrors Discourse.

Mirroring docs.ros.org 

Mirroring the documentation site requires specific configuration to prevent search engine fragmentation. If you are interested in hosting a regional mirror of the documentation, please contact the infrastructure team via Discourse before proceeding.
