Comments? PDAL uses Alpine+Docker for its TravisCI builds. The approach definitely has some useful bug replication benefits, especially when we need to take something locally for more intense debugging or we want someone to reproduce a bug with a specific configuration. It is also convenient that people can fetch the same base images from DockerHub and build their own using our Travis configuration as a guide.
The downside of docker for CI testing is one more layer of stuff to go wrong. We switched from using Ubuntu to Alpine in an attempt to get smaller images, with some painful success. Alpine images were definitely smaller, but not always as convenient, and the packaging story is less rigorous IMO. I'd say we're indifferent to Alpine vs. Ubuntu at this time, and we'd probably just stick with Ubuntu given our experience.
