Catalogue Service

This service is responsible for showing the list of items that are to be sold by the RobotShop e-commerce portal.

This service is written in NodeJS, Hence need to install NodeJS in the system.

# yum install nodejs make gcc-c++ -y 

Let's now set up the catalogue application.

As part of operating system standards, we run all the applications and databases as a normal user but not with root user.

So to run the catalogue service we choose to run as a normal user and that user name should be more relevant to the project. Hence we will use roboshop as the username to run the service.

# useradd roboshop

So let's switch to the roboshop user and run the following commands.

$ curl -s -L -o /tmp/catalogue.zip "https://github.com/roboshop-devops-project/catalogue/archive/main.zip"
$ cd /home/roboshop
$ unzip /tmp/catalogue.zip
$ mv catalogue-main catalogue
$ cd /home/roboshop/catalogue
$ npm install 

NOTE: We need to update the IP address of MONGODB Server in systemd.service file

Now, lets set up the service with systemctl.

# mv /home/roboshop/catalogue/systemd.service /etc/systemd/system/catalogue.service
# systemctl daemon-reload
# systemctl start catalogue
# systemctl enable catalogue
