  • The Web/Frontend is the service in RoboShop to serve the web content over Nginx.
  • This will have the web page for the web application.
  • Developer has chosen Nginx as a web server and thus we will install Nginx Web Server.

Install Nginx

dnf install nginx -y

Start & Enable Nginx service

systemctl enable nginx

systemctl start nginx

Try to access the service once over the browser and ensure you get some default content.

http://<public-IP>:80

Remove the default content that web server is serving.

rm -rf /usr/share/nginx/html/*

Download the frontend content

curl -o /tmp/web.zip https://roboshop-builds.s3.amazonaws.com/web.zip

Extract the frontend content.

cd /usr/share/nginx/html

unzip /tmp/web.zip

Try to access the nginx service once more over the browser and ensure you get roboshop content.

Create Nginx Reverse Proxy Configuration.

vim /etc/nginx/default.d/roboshop.conf

Add the following content

vim /etc/nginx/default.d/roboshop.conf 

proxy_http_version 1.1;
location /images/ {
  expires 5s;
  root   /usr/share/nginx/html;
  try_files $uri /images/placeholder.jpg;
}
location /api/catalogue/ { proxy_pass http://localhost:8080/; }
location /api/user/ { proxy_pass http://localhost:8080/; }
location /api/cart/ { proxy_pass http://localhost:8080/; }
location /api/shipping/ { proxy_pass http://localhost:8080/; }
location /api/payment/ { proxy_pass http://localhost:8080/; }

location /health {
  stub_status on;
  access_log off;
}

Ensure you replace the localhost with the actual ip address of those component server. Word localhost is just used to avoid the failures on the Nginx Server.

Restart Nginx Service to load the changes of the configuration.

systemctl restart nginx
