The {self.title} Container Image

Purpose

This chart deploys a SUSE Repository Mirroring Tool (RMT) server on Kubernetes. It is tested on K3s but should work on any Kubernetes distribution.

Overview

Every component of the stack is deployed in a dedicated container via a Helm Chart to ease deployment on top of Kubernetes.

Repository Mirroring Tool (SUSE RMT) server

A containerized version of the SUSE RMT application, with the ability to pass its configuration via Helm values. Persistent storage is on a Persistent Volume, thus you need to adapt its size depending on the number of repositories you need to mirror.

MariaDB

The database backend for RMT. RMT does create the database/tables at startup if needed so no specific post-installation task is required for it to be usable. Passwords are self-generated unless explicitly specified in the values file.

NGINX

The web server with proper configuration for RMT routes. Having a properly configured web server out of the box allows you to target your ingress traffic (for RMT) to it directly. You don't have to configure ingress for RMT specific paths handling, as NGINX is configured to do so.

Prerequisites

• a running kubernetes cluster
• helm (v3) command configured to interact with this cluster

Custom mandatory values

Some values of this chart do not have any sensible defaults:

• SCC mirroring credentials, please have a look here for more information
• list of products to mirror
• list of products to not mirror
• DNS name the RMT server should be reachable at
• Configured storage

You should fill a custom values file before deploying the chart.

Below example also enables ingress with TLS. The create-certs.sh can be used to create self-signed certificates and add them to Kubernetes as a usable TLS secret.
