Module installation
The most important BIIGLE modules are already included in the distribution configuration of biigle/biigle. In some cases you may want to install additional modules, though. Official BIIGLE modules come with installation instructions in their readme. However, these are always written for a "standard" installation of a PHP package and not for the Docker setup of biigle/biigle. The installation instructions of a module have to be adapted for an installation based on the biigle/biigle setup.
The installation of a BIIGLE module usually follows the same steps: Require the module using Composer, add the module service provider to the core configuration, run the command to publish module assets, update environment variables and/or the module configuration. For biigle/biigle, these steps can be performed as follows:
1. Require the module using Composer
In biigle/biigle, modules are installed in the build.dockerfile file. To require a new module (or any other PHP package), add it to the composer require command arguments in this file. The default modules that are installed use Docker build arguments to specify their version constraints. These can be configured in the build.sh file.
2. Add the module service provider
Module service provider classes are added to the core configuration with sed file modification commands. Add te service provider class to the list of modification commands to include the module that should be installed.
3. Publish module assets
The command to publish module assets is already included in the build.dockerfile file.
4. Update environment variables
New environment variables can be added to the build/.env file. This file is used when the Docker images of your BIIGLE instance are built.
5. Update the module configuration
Module configuration files can be added to the build/config directory. You can also modify existing configuration files there (e.g. filesystems.php). When you add a new configuration file, also add a corresponding COPY command to build.dockerfile.
