A Docker image that's configured to run OnEarth can be built using the ./bin/build_el7_docker_image.sh script. The script takes a single parameter, the tag to apply to the image.
The new images is built from a Docker image that has the gibs-gdal RPMs installed already. The name of that image is set in the docker/el7/gibs-gdal-image.txt file.
Example of building an OnEarth Docker image:
./bin/build_el7_docker_image.sh gibs/onearth:v1.3.1
The generated image will start Apache when it is run. The image will expect the configuration to be located at /mnt/config.
