| This directory exists for Docker Hub's automatic image building. The hooks | |
| here override the default build, test and push commands used by Docker Hub | |
| to build the published Docker images of Drill. The reason they are overridden | |
| is so that we can produce Docker images based on multiple OpenJDK base images, | |
| all using a single Dockerfile. Also see | |
