Docker Compose Configuration for Vapor

This Docker Compose configuration file is intended to help you set up a development and testing environment for your Vapor application using Docker. It includes services for your Vapor app, a database, and migration/reversion processes. Please note that this setup is primarily for testing and may not adhere to best practices for production deployments.

Prerequisites

Before using this Docker Compose configuration, ensure that you have the following prerequisites:

  • Docker: Make sure Docker is installed on your system.

Usage

You can use this Docker Compose file to build and run your Vapor application in a Dockerized environment. Here are some common commands and steps:

  1. Build Docker Images:

    Before running your application, build the Docker images using the following command:

    docker-compose build

  2. Start the Application:

    To start your Vapor application, use the following command:

    docker-compose up -d

  3. Run Migrations: You can run the database migrations with the following command:

    docker-compose run migrate

Environment Variables

This Docker Compose configuration utilizes environment variables defined in the .env file. These variables include:

LOG_LEVEL: Log level for your Vapor app.

DATABASE_HOST: Hostname for the PostgreSQL database.

DATABASE_NAME: Name of the PostgreSQL database.

DATABASE_USERNAME: Username for the PostgreSQL database.

DATABASE_PASSWORD: Password for the PostgreSQL database.

You can customize these variables in your .env file.

Notes

  • The configuration includes services for the Vapor app, migrations, and the PostgreSQL database.
  • Make sure to adjust the image field in the app, migrate, and revert services to match your Vapor application image.
  • The depends_on directive ensures that services start in the correct order.
  • The database data is stored in a Docker volume to persist data across container restarts.

This Docker Compose setup provides a convenient way to develop and test your Vapor application in a Dockerized environment. Adjust the configuration as needed for your project, and always consider security and best practices when moving to a production deployment.
