Docker image customization

The docker image is built from the Dockerfile in this repository. You can customize the docker image by modifying the Dockerfile and rebuild the image.

Build the docker image

To build the docker image, you need to install Docker on your local machine. Once Docker is installed, you can build the docker image by running the following command:

docker build -t <your-docker-image-name> src/.

Then tag the image and push it to your Docker Hub account.

docker tag <your-docker-image-name> <your-docker-hub-username>/<your-docker-image-name>
docker push <your-docker-hub-username>/<your-docker-image-name>

A Github action named Docker is also provided to build and publish the docker image to yourDocker Hub account without having to do it locally. Once you have customized the Dockerfile, you can push the changes to the master branch of this repository. The Github action will be triggered to build and publish the docker image to Docker Hub.
