Deploying a go application and a redis cluster in minikube

In my previous post, I wrote a go application that displays the GPS location of any IP address. Here in this post, I’ll explain how to deploy the same in minikube.

Prerequisites

understanding of kubernetes components (pods, deployment, etc.)
minikube installed in your laptop

Kubernetes tutorial

If you are new to kubernetes and want to learn, I recommend this youtube playlist.

Minikube

Minikube is a tool that makes it easy to run Kubernetes locally. Minikube runs a single-node Kubernetes cluster inside a Virtual Machine (VM) on your laptop for users looking to try out Kubernetes or develop with it day-to-day.

_if you don’t have minikube installed in your laptop, you can do it by following the instructions _here.

Desired Deployment State

2 instances of our web application.
**a load balancer **that balances the load on our two web application instances.
a redis cluster with a master-slave replication.

desired deployment state

I’m going to list down 7 steps I did to get to the above shown desired state. I hope you can replicate what I did very easily in your own minikube environment.

Step 1: start minikube

minikube start

you should receive an output like this

MacBook-Pro-2:Desktop jeshocarmel$ minikube start
😄  minikube v1.12.3 on Darwin 10.14.3
✨  Using the hyperkit driver based on existing profile
👍  Starting control plane node minikube in cluster minikube
🏃  Updating the running hyperkit "minikube" VM ...
🐳  Preparing Kubernetes v1.18.3 on Docker 19.03.12 ...
🔎  Verifying Kubernetes components...
🌟  Enabled addons: default-storageclass, storage-provisioner
🏄  Done! kubectl is now configured to use "minikube"

To ensure minikube has started successfully, run the command below

minikube status

and you should receive an output like this.

#kubernetes #redis #golang #containers #minikube
