Once verification scores for each valid time have been computed in the MET container, the METviewer database can be loaded and the user interface can be launched in your web-browser to compute summary statistics and display them. There are two options for establishing the image from which the software container will be instantiated. Please follow the appropriate section below that fits your needs.
Option 1: Pull the dtcenter/metviewer image from Docker Hub
If you do not want to build the image from scratch, simply use the prebuilt image by obtaining the tar file and loading it.
docker pull dtcenter/nwp-container-metviewer:${PROJ_VERSION}
If you followed all the instructions up to this point in the tutorial, the output should look similar to this:
REPOSITORY | TAG | IMAGE ID | CREATED | SIZE |
dtcenter/wps_wrf | 3.5.1 | 9b2f58336cf9 | 3 hours ago | 3.22GB |
dtcenter/nwp-container-met | 3.5.1 | 9e3d0e924a30 | 3 hours ago | 5.82GB |
dtcenter/upp | 3.5.1 | 82276dfccbc3 | 4 hours ago | 3.36GB |
dtcenter/nwp-container-metviewer | 3.5.1 | f2095355127f | 4 hours ago | 2.8GB |
dtcenter/python | 3.5.1 | 7ea61e625dff | 4 hours ago | 1.28GB |
dtcenter/gsi | 3.5.1 | c6bebdbfb674 | 5 hours ago | 2.88GB |
Option 2: Build the dtcenter/metviewer image from scratch
To access the METviewer database and display system from the Git repository and build the verification software from scratch, first go to your project space where you cloned the repository:
and then build an image called dtcenter/metviewer:
This command goes into the metviewer/METviewer directory and reads the Dockerfile directives. Please review the contents of the metviewer/METviewer/Dockerfile for additional information.
To see what images you have available on your system, type:
Option 3: Pull the dtcenter/metviewer Docker Hub image and convert it to a Singularity image
If you are using Singularity rather than Docker, the commands are similar:
singularity pull docker://dtcenter/nwp-container-metviewer-for-singularity:${PROJ_VERSION}
Unlike Docker, Singularity does not keep track of available images in a global environment; images are stored in image files with the .sif extension. Use the `ls` command to see the image file you just downloaded
