ramenctl

Command line tool and Go module for managing and troubleshooting Ramen.

Overview

Working with a complicated Kubernetes cluster is not easy. In a typical disaster recovery environment we have at least 3 connected Kubernetes clusters with many components. The ramenctl project aims to make it easier to manage and troubleshoot this challenging environment.

Features

The project provides:

• The ramenctl command line tool, managing and troubleshooting ramen.
• The ramenctl Go module for integrating the ramenctl commands in other projects. This module is used to implement the odf dr command.
