OpenDrift

This recipe for a containerized OpenDrift was provided by a user and is hopefully useful for others.

In a project folder (the home folder is likely not large enough), run the following:

$ singularity pull docker://opendrift/opendrift

This downloads a large file (opendrift_latest.sif) which provides OpenDrift in a container image.

Then create a Python script which imports opendrift:

import opendrift

print("the import worked well")

This script can then be run using:

$ ./opendrift_latest.sif python myscript.py

It is also possible to open python and run OpenDrift interactively using:

$ ./opendrift_latest.sif python

For this to work, you might have to mount specific catalogues (for example where the ocean model forcing files are) using SINGULARITY_BIND:

$ export SINGULARITY_BIND="/cluster"

If more directories are needed, they can be added through:

$ export SINGULARITY_BIND="/cluster,/opt,/data"
