A few files need to be modified to adapt the environment to the project's needs.

Defines environment variables common across the containers. This file contains some default values that need to be modified according to your project's requirements:

• GIT_AUTHOR_NAME and GIT_AUTHOR_EMAIL are used by Git.

• CONTAINER_USER is the name of the user account in the containers and also the name of the user's home directory.

• REPOSITORY is the name of the folder where the repository is located, within the home directory: /home/$USER/$REPOSITORY.

This directory should contain a private and public key for authentication to the repository. The credentials are only exposed to the Git container to ensure that no malicious code in the development or testing containers can steal them.

A script that watches the source directory, expected to be located at /home/$USER/$REPOSITORY/src/ for changes and runs a sequence of commands intended to compile the package and place it in the /home/$USER/$REPOSITORY/dist/ directory. Note: The actual build sequence is not yet implemented.

The environment defines three separate containers that need to be created by running the following command once in the project's root directory:

docker-compose build

To clone an existing repository, or create a new one, start a shell in the Git contaner:

docker-compose run git

To ensure the security of the credentials, the Git container must only contain software from trusted sources. This container should be used to push changes, and if your project resides in a private repository, also to fetch changes.

Caution: Do not run untrusted scripts or executables in the Git container.

The Dev container is configured to run as a Docker service and is started with:

docker-compose up -d dev

It runs in the background and automatically triggers the build sequence when it detects changes in any of the source files.

The build script expects that the source code of the EPUB package is located in the /src directory. And the test script expects that the build artefact is placed in the /dist directory. If your project is layed out differently, update the scripts accordingly.

The Dev container should be responsible for setting up third party dependencies and is assumed to run potentially unsafe code.

As a convenience for Visual Studio Code users, the code.sh script starts the Dev container and runs Code in remote development mode towards it. Since the container has Git installed, code changes can be committed from within. However, to push the changes to the repository, the Git container needs to be used.

The Test container executes the script at scripts/test.sh, which monitors the /dist directory for updates and runs the EPUBChecker tool from W3C against the built aretefact. Currenly, it is hardcoded as book.epub. You may need to adjust the expected file name in the script accordingly.

To verify the EPUB package's conformance to the specification:

docker-compose run test
