Docker Node 🐳: learn best practices

About the project

A simple Node.js project with Docker, MongoDB and MySQL

Setting up the project

You'll need to configure the environment variables for the project. To do this, you can create a .env file in the root of the project with the following content:

# Docker Configuration
# Defining true you are saying that you are running the application in a docker environment.
# Otherwise (false), you are running the application in a local environment.
IS_DOCKER_ENV=<flase | true>

# Application Configuration
APP_CONTAINER_NAME=<app_container_name>
APP_PORT=<app_port> # Default: 3000

# MySQL Configuration
MYSQL_CONTAINER_HOST=<mysql_container_host>
MYSQL_PORT=<mysql_port> # Default: 3306
MYSQL_DATABASE=<mysql_database>
MYSQL_ROOT_USER=<mysql_root_user>
MYSQL_ROOT_PASSWORD=<mysql_root_password>

# MongoDB Configuration
MONGO_CONTAINER_HOST=<mongo_container_host>
MONGO_DATABASE=<mongo_database>
MONGO_PORT=<mongo_port> # Default: 27017

Also, you can look at the .env.example file to see an example of the environment variables.

Running the project

To run the project, you'll need to have Docker installed. Then, you can run the following command:

docker-compose up

For building the project, you can run the following command:

docker-compose up --build

This will build the Docker image and start the container. You can access the application at http://localhost:3000.

Stopping the project

To stop the project, you can run the following command:

docker-compose down

This will stop the container and remove it.
