Blog backend application

Blog backend application is developed using micro service architecture. The project has four micro services, these are Api Gateway, Identity Server, BlogApi Server and Notification Server.

Backend architecture

How the project is structured?

Each micro service has its own repository. You can reach the repositories from here:

• API Gateway
• Identity Server
• Blog Api Server
• Notification Server

The BlogApp repository has two main folders, one is composes and another is scripts.

• composes folder has docker-compose files for micro services and common services like postgresql, rabbitmq etc.
• scripts folder has git-clone.sh that clones above repositories and compile.sh.

How to start the project?

• Run the compile.sh script file under the folder BlogApp/scripts. This will clone all the repositories, build and run them as docker containers. This will also build and run common services defined in infrastructure.yml file under BlogApp/composes folder .
• Visit http://localhost:5000 from your browser and you will get hello world message.

Important Notes

Before you run compile.sh, you have to create the following environment variables:

• EMAIL_PASSWORD to store email password.
• EMAIL_SERVER your email server name.
• EMAIL_NAME your email name.
