Hello,

does anyone know, whether the Dockerfiles used for building the images offered on the openfoam.org download page are publicly available?

Where would I find these?

Thanks in advance

Hi Muerio,

In the installation instructions in step 4, it asks you to download and run this script:

http://dl.openfoam.org/docker/openfoam10-linux

There you can see that the image is: openfoam/openfoam10-paraview56 for the current version. On docker hub (https://hub.docker.com/r/openfoam/op...araview56/tags), by clicking on the tag you can view the steps that constitues the docker image.

I am not sure if the text versions of the openfoam releases are stored elsewhere.

Hi ukaya,

thank you for your reply.

I already looked at the details for the individual tags.
Unfortunately you can't get all the information you need from it.
Especially the files copied into the images.

I really hoped to find a repository of the Dockerfile somewhere so I could fork the entire setup and use it to build the image on a more frequent basis.

Hi Muerio,

You are right. Nevertheless, more or less the only critical step is "apt-get install ..."

I have come across these dockerfiles: https://github.com/PawseySC/pawsey-containers, which I use for building docker images for debugging openfoam. You might find them useful.

Cheers

The www.openfoam.com docker files are publicly available, and their use for making your own images is actively encouraged.
https://develop.openfoam.com/packaging/containers


contains templates for a variety of distributions and different compositions of openfoam. The nss-wrapper solution corresponds to the openfoam-docker start script, but there are also some chroot versions that can be useful while building content.


EDIT: just added some preliminary definition files for apptainer/singularity (doesn't need nss-wrapper at all).

Thanks a lot for that.
Anyone knows about a repository with the Dockerfiles for the OpenFOAM.org flavour?
(Although after having a look to those for ESI flavour, the recipes are indeed not particularly useful for my purposes, as they are simple installations using apt-get install rather than an installation from source. I guess Dockerfiles from the "Foundation" flavour are going to be the same, simple use of apt-get install within an Ubuntu container.)

If you dig deeper on https://develop.openfoam.com/packaging/containers you will notice there are actually some additional files there too.
The https://develop.openfoam.com/packagi...ntu.Dockerfile (for example) sets up a container for building OpenFOAM. You can then either use/reuse a deb file for building, following the packages debian rules, or else simply do a regular OpenFOAM build (ie, with wmake) after using foamConfigurePaths to select system components for scotch, mpi, etc.


An alternative approach is noted in the wiki information: https://develop.openfoam.com/packagi...s/-/wikis/home


This describes using a rocky image for building the binary content and then re-deploying that content for a UBI (RedHat binary image). Not sure what other combinations you'd want.
