Project Software For Cloud

Description

This project is based on the "Bibliotech" project. Link : https://github.com/PlugNPush/BiblioTech

The goal of this project is to deploy the different microservices (the database, the server, the recommendation and the front) of the project Bibliotech on kubernetes.

It is not working on Windows as the images are built on macOS.

Installation

You need to have installed on your computer :

• Docker
• Minikube
• Kubectl
• istio (a service mesh) : https://istio.io/latest/docs/setup/getting-started/
• Helm : https://helm.sh/docs/intro/install/

Deployment

To deploy the project, you need to run the following command :

cd ./kubernetes
bash launcher.sh

It will launch minikube, then create the different clusters and give you the ip of the front in which it is accessible.

Description of the project

The project is composed of 4 microservices all communicating through a Rest API :

• The database : it is a MySql database with values already inserted in it.
• The server : it is a node.js server that will communicate with the database.
• The recommendation : it is a python server that will return recommendations.
• The front : it is a React front that will display the books and the recommendations of the user. I communicate with the server and the recommendation services.

So we have four kubernetes files to create the deployments and the services for each microservice.

We also use istio for different reasons :

• To create a gateway to access the different services.
• To create a virtual service to redirect the traffic to the different services and using the same url as basis.
• To solve Cors problems between the front end and the server.

Helm

We configured helm to automate the deployment of the clusters. But first you have to download istio to the helm directory. Run the following command to install istio on helm :

cd ./helm
helm repo add istio https://istio-release.storage.googleapis.com/charts
helm repo update

Then you can run helm to install the different clusters (you have to be in the helm directory, if you executed the previous command you are already in the good place) :

helm install cloud ./helm-cloud

Finally, to get the url of the front and do the port forwarding of istio, you can run the following command :

bash ./../kubernetes/ingress-forward.sh &
echo To access the website you can go on the following url :
minikube service front --url

Another solution is to launch the launcher.sh script in the helm directory.

cd ./helm
bash launcher.sh
