invmanr_api

invmanr_api is a C++ application that runs inside a Docker container and connects to a MySQL database. This guide provides instructions on how to build and run the Docker image.

Prerequisites

• Docker installed on your system
• MySQL database running and accessible
• Environment variables for database credentials

Build the Docker Image

Build the Docker image using the following command:

docker build -t invmanr_api .

This command builds the Docker image and tags it as invmanr_api.

Run the Docker Container

1. Ensure that your MySQL database is running and accessible.

2. Run the container with the required environment variables:

   docker run --rm \
   -e DB_HOST=<your-db-host> \
   -e DB_USER=<your-db-user> \
   -e DB_PASSWORD=<your-db-password> \
   -e DB_NAME=<your-db-name> \
   -p 18080:18080 \
   invmanr_api

   • Replace <your-db-host>, <your-db-user>, <your-db-password>, and <your-db-name> with your actual database credentials.
   • The -p 18080:18080 flag maps the container port to the host, making the app accessible at http://localhost:18080.

3. After running, you can verify the service by visiting http://localhost:18080 in your browser.

Environment Variables

The application requires the following environment variables:

• DB_HOST: The hostname or IP address of the MySQL database.
• DB_USER: The username for the database connection.
• DB_PASSWORD: The password for the database connection.
• DB_NAME: The name of the database to connect to.

Clean Up

To stop and remove the container, simply use Ctrl+C if it's running interactively or run:

docker container stop $(docker ps -q --filter ancestor=invmanr_api)

To remove the built Docker image:

docker rmi invmanr_api
