This repository allows a base installation of the CORAL-ERM software to be run within Docker containers. It is currently hardcoded to pull CORAL 3.0.0 as its code.

This repository assumes that Docker is installed on the local machine. If not, please install Docker via the instructions on the official Docker site.

To start CORAL-ERM in Docker containers, run the following command:

docker-compose up --build

This will build two containers for CORAL - the PHP frontend and the Database backend.

The database container is based on MariaDB and currently uses the most recent version available via Docker Hub.

It will use the environment variables listed in the Docker Compose file, including setting a root MySQL password, creating a database for CORAL-ERM, and a username and password for the created CORAL-ERM database. These values can be changed by editing the docker-compose.yml file.

The MariaDB container will have port 3306 exposed to the localhost on port 3306. This can be adjusted as needed.

The MariaDB container will start and run a healthcheck to ensure that the database service is running and reachable via the root name and password. This will preclude using the MYSQL_RANDOM_ROOT_PASSWORD environment variable.

In the Dockerfile within the repository, we define the front-end PHP server. Based on the current CORAL-ERM documentation, we begin with a PHP-provided Apache container and install the git command line tools and the required PHP extensions.

Next, we copy in a PHP configuration file to ensure that the proper PHP extensions are installed on the machine.

Our next step is to clone the 3.0 tagged version of CORAL-ERM into the /var/www/html folder, and change permissions to allow CORAL's setup to write configuration files.

Next, we write some basic values to the base apache2/httpd.conf file to handle some basic errors that are thrown.

Lastly, Apache is launched as a daemon in the foreground to ensure the front-end container stays up and running.

Once the containers are running, you can access the CORAL-ERM installation page by visiting http://localhost:8080/coral/index.html and step through the installation - the documentation for this is located on the official CORAL-ERM page.

There is one issue where after CORAL-ERM installation completes, the application would like to remove the write access to the configuration files.

On a basic stack, this can be accomplished by running the following from a Linux command line prompt:

docker exec -t coral-docker_web_1 chmod 755 -R /var/www/html/

This will run a permission change on the needed directories. Once it is complete, you should be able to click the "Try Again" button on the bottom of the error page within CORAL-ERM.

• We would like to move from the PHP 5.6-apache image to a more lightweight image such as Alpine Linux but this is a premature optimization for the containerization project.
