I love exploring open GIS datasets with QGIS. It's incredible what this tool can do and I keep discovering new features or plugins all the time, which keeps it interesting. The amount of publicly available GIS data combined with tools like QGIS and PostGIS can be a big time saver. I don't work in the space, but occasionally run into problems requiring some form of support for geospatial data. Need a list of US cities and postal codes along with their respective coordinates? Easy. Find the dataset, import into QGIS, export to PostGIS. Done.

I can second this. We were up-and-running with Docker on our dev machines in just a few minutes. A native installation involves substantially more setup (Python, databases, Redis and/or Rabbit, etc.). The published docker-compose file will handle all of that for you. We have a very small data engineering team and have been able to move very quickly with Docker and AWS ECS (for orchestrating containers in test and prod environments).
