codedx-docker

This repository lets you create a Code Dx installation using Docker Compose. A Docker-based installation of Code Dx contains two parts: the database image, based on MariaDB, and the Tomcat image that hosts the Code Dx web application. The Tomcat Docker container will be networked with the MariaDB container to allow Code Dx to store data.

The installation uses docker-compose to stand up a functional instance of Code Dx automatically, pulling the Tomcat/Code Dx image from Docker Hub, and starting a properly configured MariaDB container.

Installation

Overview

This section details how to start up a functional instance of Code Dx using Docker, accessible via port 8080.

Instructions

1. Install Docker using these instructions.
2. Install docker-compose.
3. If desired, edit the following values in the docker-compose.yml file.

• The following configuration values affect the database container:
  • MARIADB_ROOT_PASSWORD: The password for MariaDB's root user.
  • MARIADB_DATABASE: The name of the database to be created automatically when the container is started.
• The following configuration values affect the Tomcat based Code Dx container:
  • DB_URL: The url that Code Dx uses to connect to it's database.
  • DB_DRIVER: The jdbc database driver that Code Dx uses.
  • DB_USER: The database user Code Dx connects with.
  • DB_PASSWORD: The password Code Dx connects with.
  • SUPERUSER_NAME: The root administrator name for Code Dx.
  • SUPERUSER_PASSWORD: The password for the Code Dx root administrator.
  • ports: The list of values underneath this header controls the ports forwarded from the Docker instance to the host machine. The left value represents the port bound on the host machine, the right value represents the port bound in the Docker container. If there is a port conflict on the host machine, alter the left value.

4. Run docker-compose up. Alternatively, run docker-compose up -d to detach and run in the background.
5. When the message "The Server is now ready!" appears in the console, navigate to http://localhost:8080/codedx to log into your newly spun up Code Dx instance.
6. To stop, run docker-compose stop, and to remove the Docker containers automatically created, run docker-compose down.

Note: If you want to migrate data from an existing Code Dx system, refer to these instructions.

HTTP Over SSL

This Tomcat container can support HTTP over SSL. For example, generate a self-signed certificate with openssl (or better yet, obtain a real certificate from a certificate authority):

openssl req -new -newkey rsa:4096 -days 3650 -nodes -x509 -subj "/C=US/ST=New York/L=Northport/O=Code Dx/CN=localhost" -keyout ./ssl.key -out ./ssl.crt

The server.xml file contains a configuration that supports SSL using Tomcat's SSL capability.

This template can be mounted over the existing server.xml in the Docker image. The SSL certificate and private key must also be mounted.

To configure, edit the docker-compose.yml codedx-tomcat section to look like:

    codedx-tomcat:
        image: codedx/codedx-tomcat:v5.2.13
        environment:
            - DB_URL=jdbc:mysql://codedx-db/codedx
            - DB_DRIVER=com.mysql.jdbc.Driver
            - DB_USER=root
            - DB_PASSWORD=root
            - SUPERUSER_NAME=admin
            - SUPERUSER_PASSWORD=secret
        volumes:
            - codedx-appdata:/opt/codedx
            - /path/to/ssl.crt:/usr/local/tomcat/conf/ssl.crt
            - /path/to/ssl.key:/usr/local/tomcat/conf/ssl.key
            - /path/to/server.xml:/usr/local/tomcat/conf/server.xml
        ports:
            - 8443:8443
        depends_on:
            - codedx-db

After following the rest of each method's respective setup instructions, Code Dx should now be available over https at the following url: https://localhost:8443/codedx
