Setting up Submariner

This guide explains how to install and configure Submariner to connect multiple Kubernetes clusters using either Kind or OpenShift.

Installing the subctl binary

Submariner provides a script to download and install the latest subctl binary:

curl -Ls https://get.submariner.io | bash
export PATH=$PATH:~/.local/bin
echo export PATH=\$PATH:~/.local/bin >> ~/.profile
For more installation options, refer to the Submariner documentation
