minikube

This module provide instructions to prepare a local minikube cluster.

Minikube is going to take care of most of the work by spawning a local kubernetes cluster.

Getting started

Prerequisites

Download & install the following tools to your workstation:

1. Install minikube (First step only).
2. Install tools from Prerequisites

Create a new minikube cluster

1. Run minikube start -p dss-local-cluster to create a new cluster.
2. Run minikube tunnel -p dss-local-cluster and keep it running to expose LoadBalancer services.

If needed, you can change the name of the cluster (dss-local-cluster in this documentation) as needed. You may also deploy multiple cluster at the same time, using different names.

Access to the cluster

Minikube provide a UI, should you want to keep track of deployment and/or inspect the cluster. To start it, use the following command:

1. minikube dashboard -p dss-local-cluster

You can also use any other tool as needed. You can switch to the cluster’s context by using the following command:

1. kubectl config use-context dss-local-cluster

Upload or update local image

Should you want to run the local docker image that you built, run the following commands to upload / update your image

1. minikube image -p dss-local-cluster push interuss-local/dss

In the helm charts, use docker.io/interuss-local/dss:latest as image and be sure to set the imagePullPolicy to Never.

Deployment of the DSS services

You can now deploy the DSS services using helm charts.

Follow the instructions in the README, especially the ones related to certificate generation and publication to the cluster. However, there are some minikube specific things to do:

• Use the global.cloudProvider setting with the value minikube and deploy the charts on the dss-local-cluster kubernetes context.
• To access the service, find the external IP using the kubectl get services dss-dss-gateway command. The port 80, without HTTPs is used.

Clean up

To delete all resources, run minikube delete -p dss-local-cluster. Note that this operation can’t be reverted and all data will be lost.
