Building using Docker

1. Setup requirements

To use Docker, you'll need either Docker Desktop or Docker Toolbox installed and setup based on your system.

On Ubuntu, Docker and required tools can be installed with: sudo apt install docker.io docker-compose docker-buildx

You'll also need to prepare a local version of the project with a copied base ROM (see steps 2 and 3 of the Linux instructions).

2. Create and start the Docker image build

From the root of your local project, run the following command:

docker-compose up --build

This should immediately begin steps 4 and 5 within the Docker container.

3. Shell into the 'oot' container

To exec into the oot Docker image at any time, run the following command either during or after the build:

docker-compose exec oot bash
