Usage

Requirements:

• Kind ( node-image >1.16.x )
• Helmsman
• Docker / Buildah ( with Docker alias )

This demo deploys ingresses for *.testing.com.
To make it work you have to rewrite the DNS answers to localhost.

For Linux it has been as simple as adding this line to your network manager ( tested with Arch/Gnome )
echo "address=/testing.com/127.0.0.1" > /etc/NetworkManager/dnsmasq.d/testDomains.conf

Create Cluster

To create a kind cluster and add the kubecontext to your config run make create-kind-cluster

In case you need to create the kind cluster using root permissions execute instead sudo -E make create-kind-cluster

Prepare App images

Build and upload the resulting images to your kind cluster sudo make prepare-apps

Setup the environment

make prepare-environment will setup all applications in your cluster
