Ingress Example

Install

The installation will slightly depend on the type of cluster that you are using.

For this tutorial, we are going to be using the docker-desktop cluster

We need two main components

1. Ingress Controller
2. Ingress resources

Let's set everything up.

We are going to be using the NGINX Ingress Controller. With the NGINX Ingress Controller for Kubernetes, you get basic load balancing, SSL/TLS termination, support for URI rewrites, and upstream SSL/TLS encryption

First off, let's clone this repository

git clone <repository>

cd ingress-example

cd app-one

now build your Docker image

docker build -t anaisurlichs/flask-one:1.0 .

You can test it out through

docker run -p 8080:8080 anaisurlichs/flask-one:1.0

And then we are going to push the image to our Docker Hub

docker push anaisurlichs/flask-one:1.0

We are going to do the same in our second example application

cd ..
cd app-two

build the docker image

docker build -t anaisurlichs/flask-two:1.0 .

push it to your Docker Hub

docker push anaisurlichs/flask-two:1.0

Now apply the deployment-one.yaml and the deployment-tow.yaml

kubectl apply -f deployment-one.yaml
kubectl apply -f deployment-two.yaml

Make sure they are running correctly

kubectl get all

Installing Ingress Controller

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v0.44.0/deploy/static/provider/cloud/deploy.yaml

Installing Ingress Resource

kubectl apply -f ingress.yaml

make sure that everything is running correctly

kubectl get all -n ingress-nginx
