Intro

This repo is created to log the learning of Kubernetes deployments on local controlled environment using Minikube & Docker Desktop.

Preview

Commands that are used to setup and run this project.

Prerquisites

Docker desktop application.

Note - You can download the docker desktop application here.

Installation

First we install the kubectl package by Kubernetes to get access to the Kubernetes cli which we can use to manage the deployments. Use the below commands to install the kubectl.

For MacOS

brew install kubectl

For Windows

curl.exe -LO "https://dl.k8s.io/release/v1.26.0/bin/windows/amd64/kubectl.exe"

you can refer to the kubectl installation guide here.

Now we install minikube which will give us an local environment to deploy our app and db.

brew install minikube

Setup

we will create the following yaml files -

secrets.yaml
mongo-config.yaml
mongo-app.yaml
web-app.yaml

we are using mongo as the DB image & mongo-express as our application for this demo.

Deployment

Start the minikube environment -

minikube start

Apply the configs & deploy -

kubectl get pod
kubectl apply -f mongo-config.yaml
kubectl apply -f secret.yaml
kubectl apply -f mongo-app.yaml
kubectl apply -f web-app.yaml
kubectl get pod

Get the details of the pods, services, secrets, ip & node -

kubectl get configmap
kubectl get secret
kubectl get svc
minikube ip
kubectl get node -o wide

the minikube ip command will only give you the IP, for accessing the application we have to start the service -

minikube service webapp-service

we have successfully deployed the application.

After we are done we can delete the deployements using the following commands.

kubectl delete deployment --all

kubectl delete secret --all

Thank You.
