This project contains a Dockerfile and all necessary components to create a Docker container for the Community Atmosphere Model. The container is available on Dockerhub, however these versions may not always be up to date.
The Catalyst pipelines can be changed by editing fv_coprocess.py, the CAM parameters can be changed by editing build-namelist.sh and configure-cam.sh. Be aware that you may need to edit the run script when changing the number of MPI processors in the configuration so the two match. When finished with the customization, the container can be rebuilt by navigating into the source directory and executing:
$ docker build -t <mytag> .
After either pulling or building the container, it can be run by calling:
$ docker run -p 11111:11111 <mytag>.
-p 11111:11111 makes port 11111 available on the outside which is needed for ParaView. We can then connect to ParaView 5.6.0 by opening File->Connect... and adding the server localhost:11111. Also, connect Catalyst via Catalyst->Connect.... The server is now awaiting Catalyst connections. Finally either execute the workload script provided by start_simulation.sh by calling
$ docker exec -it <containerid> /home/docker/start_simulation.sh
or by executing bash in the container and navigating to the executable manually. The container id is printed by the ParaView server when starting the container, the executables paths can be found in start_simulation.sh.
