mfem: Docker Error: '/opt/mfem-env/.spack-env/view/': No such file or directory when using docker

I ran docker following the command in config/docker/README.md, as follows:

$ docker build -f config/docker/Dockerfile.base -t ghcr.io/mfem/mfem-ubuntu-base .
$ docker run -it ghcr.io/mfem/mfem-ubuntu-base bash

But after entering docker, the situation does not match the README:

$ env | grep mfem
>>> OLDPWD=/opt/mfem-env

But the output should actually be:

PKG_CONFIG_PATH=/opt/mfem-env/.spack-env/view/lib/pkgconfig:/opt/mfem-env/.spack-env/view/share/pkgconfig:/opt/mfem-env/.spack-env/view/lib64/pkgconfig
PWD=/opt/mfem-env
MANPATH=/opt/mfem-env/.spack-env/view/share/man:/opt/mfem-env/.spack-env/view/man:
CMAKE_PREFIX_PATH=/opt/mfem-env/.spack-env/view
SPACK_ENV=/opt/mfem-env
ACLOCAL_PATH=/opt/mfem-env/.spack-env/view/share/aclocal
LD_LIBRARY_PATH=/opt/mfem-env/.spack-env/view/lib:/opt/mfem-env/.spack-env/view/lib64
PATH=/opt/mfem-env/.spack-env/view/bin:/opt/view/bin:/opt/spack/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

When I tried to run some installed miniapps, I found that there was no corresponding folder:

$ ls /opt/mfem-env/.spack-env/view/
>>> ls: cannot access '/opt/mfem-env/.spack-env/view/': No such file or directory

Hey folks - happy July! And hooray for me having internet bandwidth again! Watching YouTube videos on potato poly is 😭

As promised, here is a pull request to update the Dockerfiles and instructions: https://github.com/mfem/mfem/pull/3769.

There were a few issues - first that the main logic of the base Dockerfile.base was commented out (this was a mistake likely on my part that I missed before we merged) and I don’t think I did a good job of presenting the builds in the context of use cases, e.g.,:

“I want to develop mfem itself, and I can use spack” (base)
"I want to use a built mfem for my own app (non-base, multi-stage slimmer build)

Please check out the PR, and instructions, and let’s follow up with discussion there.

It’s late and I am reading on my phone, but the base image needs to build first, and then the image on top of it, and that’s the container being shelled into (not the base). The difference is small - copying the environment from one place to another:

https://github.com/mfem/mfem/blob/19c16996d5117a13cc7242d7bfbe88342053285f/config/docker/Dockerfile#L14

I’ll take a closer look tomorrow when I’m more awake!
