Due to OpenCoarray not being available in the package repository in Fedora Linux, I have prepared a Fedora-based docker/podman image, with opencoarray already installed:
The usage/installation instructions are in the repo.
Why fedora? Because it is my favorite linux distro, but also it usually ships with a recent version of gfortran, providing good coverage of Modern Fortran features (as of Feb 2022, it is gfortran 12).
If you have any comments or improvement ideas, please let me know!
