bthoven/astrometrynetweb repository overview

I'm grateful to Dustin Lang for his source codes and the ready-to-build Dockerfile. Although he maintains official Docker Hub repositories at "https://hub.docker.com/r/astrometrynet/webservice/tags⁠", I've noticed that sometimes the images are not built immediately following his latest updates. I tend to build the latest release as soon as I become aware of a new version he has released.

To run the "bthoven/astrometrynetweb:xxx" docker:

1. you must have a host folder containing your index files and map it to "/index" folder in the container
2. The astrometry config file must be named "config.cfg". The default config file is created when you spin up a container. However, if you want to tweak it, you must create a "config.cfg" file inside your index folder, on the host, where you store all index files. So basically, both the config file and index files are stored in the same folder. You don't have to map your host "docker.cfg" file to the container "docker.cfg" file.
