This is the second in a series of posts aimed at developing a set of containers that can be quickly deployed to enable web mapping in a production environment. At the conclusion of the first post, we had an empty PostgreSQL database container serving a django container running the development server on port 8000. The next steps are to get PostGIS for a database and enable spatial queries using GeoDjango.
The long term goal of this series of posts is to develop a set of ready to use tools that will enable the rapid setup of web mapping servers that can be prototyped, developed, and moved to production without a lot of embarrassing oversights. The key technologies that I want to use are:
