At the core of successful web projects lies a database, be it SQL or NoSQL, relational or object-relational. There, your articles, products, posts, and user-data are being stored and held ready for request.
sloppy.io offers a wide variety of database solutions, based on the whole catalogue of images on Docker Hub. In this article, I will give you an overview of the most popular db solutions and how to set them up.
Guidelines and step-by-step instructions
Here's what you basically need:
- the Docker image of your preferred database-management system
- a web-based administration tool to go with it
Keep in mind that due to security reasons, we're not exposing any TCP ports, so you'll need a web-based solution for administration purposes.
That said, here are some beginner-friendly tutorials for the most popular database systems out there. If you're in need of advice for a different one, just contact us.
List of database systems and administration tools
If you already know how to set your database up, here's a list of Docker images and Environment Variables for different database-management systems. This list is ongoing, so keep coming back for updates. As mentioned above, please contact us for suggestions.
