Hello there 👋

This is a simple ecommerce application backend built using the microservices architecture. Here's a series of articles I'm writing to document my journey throught the process.

Runing the application

For ease of use and easier maintainability, I've split the docker-compose files into separate based on the type of services they run.

Setting up the pre-requisites

We can setup/initialize all the pre-requisites needed for our app in docker-compose.setup.yml. These items could include stuff such as database migrations, seed data creation, creating networks and volumes, etc.

docker-compose --file docker-compose.setup.yml up

Starting the dependencies

The docker-compose.deps.yml file is used to start up all the application level dependencies such as the database, messaging broker, mailing server, etc.

docker-compose --file docker-compose.deps.yml up

Starting the services

The docker-compose.services.yml is used to start up all the application level dependencies such as the database, messaging broker, mailing server, etc.

docker-compose --file docker-compose.services.yml up

Starting the Nginx gateway

I've only put the Nginx service in the last docker-compose.gateway.yml. This is the final piece that'll make out app accessible from the outside internet.

docker-compose --file docker-compose.gateway.yml up
