Repository Mirroring Tool

This tool allows you to mirror RPM repositories in your own private network. Organization (mirroring) credentials are required to mirror SUSE repositories.

End-user documentation can be found in RMT Guide. man pages for rmt-cli can be found here.

Installation on SLE15

1. Activate your instance of SLE15 via SUSEConnect -r <regcode>
2. Activate Server Applications module SUSEConnect -p sle-module-server-applications/15/x86_64
3. Install RMT with YaST installation wizard zypper in rmt-server yast2-rmt
4. Run installation wizard for RMT yast2 rmt and configure your instance

Installation on OpenSUSE Leap 15

1. Install RMT with YaST installation wizard zypper in rmt-server yast2-rmt
2. Run installation wizard for RMT yast2 rmt and configure your instance

Manual installation and configuration

RMT currently gets built for these distributions: SLE_15, SLE_12_SP2, SLE_12_SP3, openSUSE_Leap_42.2, openSUSE_Leap_42.3, openSUSE_Tumbleweed. To add the repository, call: (replace <dist> with your distribution)

zypper ar -f https://download.opensuse.org/repositories/systemsmanagement:/SCC:/RMT/<dist>/systemsmanagement:SCC:RMT.repo

To install RMT, run: zypper in rmt-server

After installation configure your RMT instance:

• Prepare the database:
  • Start MySQL/MariaDB by running systemctl start mysql
  • Set database root user password by running mysqladmin -u root password
  • Make sure you can access to the database console as root user by running mysql -u root -p
  • Create a MySQL/MariaDB user with the following command:

  mysql -u root -p <<EOFF
  GRANT ALL PRIVILEGES ON \`rmt\`.* TO rmt@localhost IDENTIFIED BY 'rmt';
  FLUSH PRIVILEGES;
  EOFF
  

• See RMT Configuration Files in the official RMT documentation for information about /etc/rmt.conf.
• Start RMT by running systemctl start rmt-server. This will start the RMT server at http://localhost:4224.
• By default, mirrored repositories are saved under /usr/share/rmt/public, which is a symlink that points to /var/lib/rmt/public. In order to change destination directory, recreate /usr/share/rmt/public symlink to point to the desired location.

Dependencies

Supported Ruby versions are 2.5.0 and newer.

Development setup

• Install the dependencies:

  • sudo zypper in libxml2-devel libxslt-devel
  • bundle install

• Copy the file config/rmt.yml to config/rmt.local.yml to override the default settings:

  • Add your organization credentials to scc section
  • Add your MySQL credentials

• Setup MySQL/MariaDB:

• Grant the just configured database user access to your database. The following command will grant access to the default user rmt with password rmt (run it as root):

mysql -u root <<EOFF
GRANT ALL PRIVILEGES ON \`rmt%\`.* TO rmt@localhost IDENTIFIED BY 'rmt';
FLUSH PRIVILEGES;
EOFF

• Create databases by running rails db:create db:migrate
• Run rails server to run the web-server

Running with docker-compose

In order to run the application locally using docker-compose:

1. Copy .env.example file to .env;
2. Add your organization credentials to .env file. Mirroring credentials can be obtained from the SUSE Customer Center;
3. Start the containers by running docker-compose up. Running docker-compose up -d will start the containers in the background;
4. Execute commands in the container, e.g.:

   docker-compose exec rmt rmt-cli repos --help

   Alternatively, running docker-compose exec rmt bash will start the shell inside the container.
5. The web server will be accessible at http://localhost:8080/, this URL can be used for registering clients.

Is it any good?

Yes.
