 ## Built Bucket Creation Instructions

+The below commands will build the buildbucket image, tagged with the current
+date, and then push it to the container registry on gitlab.
+
+```bash
+docker build -t gitlab.ssec.wisc.edu:5555/cspp_geo/cspp-geo-gridded-glm/buildbucket:r$(date '+%Y%m%d') .
+docker push gitlab.ssec.wisc.edu:5555/cspp_geo/cspp-geo-gridded-glm/buildbucket:r$(date '+%Y%m%d') 
+```
+
+After testing the image you can tag it as latest by doing:
+
+```bash
+docker tag gitlab.ssec.wisc.edu:5555/cspp_geo/cspp-geo-gridded-glm/buildbucket:r$(date '+%Y%m%d') gitlab.ssec.wisc.edu:5555/cspp_geo/cspp-geo-gridded-glm/buildbucket:latest
+docker push gitlab.ssec.wisc.edu:5555/cspp_geo/cspp-geo-gridded-glm/buildbucket:latest
