Add devcontainer.json for development with VS Code in a Docker container

[mkoeppe]

https://code.visualstudio.com/docs/remote/containers

We add two new sections in the developer's guide:
https://47f8b984ef964a5aa34147393fbdc32e0dde88ad--sagemath-tobias.netlify.app/developer/portability_testing.html#using-our-pre-built-docker-images-published-on-ghcr-io

We also set up devcontainer configurations for the CoCalc and computop/sage Docker images, as well as downstream distribution packaging of Sage.

• Cannot rebuild sage 3-manifolds/sagedocker#2

Tested devcontainer.json of

• portability-ubuntu-jammy-standard: builds well; runs well
• develop-docker-computop: builds well; runs well
• downstream-docker-cocalc: builds well; runs well (except machines with the issue Do not require AVX when building with SAGE_FAT_BINARY #32434)
• downstream-docker-computop: builds well; runs well
• downstream-archlinux-latest: builds well; runs well
• downstream-conda-forge-latest: builds well; runs well

Follow-ups:

• Installation guide: Document Sage installation on Windows via VS Code devcontainers #34363 Installation guide: Document installation on Windows via devcontainer
• Cookiecutter for Sage user projects with devcontainer #34286 Cookiecutter for Sage user projects with devcontainer
• .devcontainer/portability-ubuntu-jammy-standard fails in GitHub Codespaces #34403 GitHub Codespaces - may also be able to test it by starting a codespace at https:https://user-images.githubusercontent.com/5037600/216875765-6697bbf8-70f9-4acc-868e-9309db67be92.jpg/new?hide_repo_select=true&ref=public%2Fbuild%2Fdevcontainer&repo=302607352&machine=standardLinux32gb&devcontainer_path=.devcontainer%2Fdevcontainer.json
• downstream-* for more distributions (generate with tox from the info in tox.ini, use _sagemath` package)
• develop-conda-forge-src-environment-dev (https://doc.sagemath.org/html/en/installation/conda.html#using-conda-to-provide-all-dependencies-for-the-sage-library-experimental, similar to our gitpod configuration)
• Restore portability-debian-buster-i386-standard and fix it
• Restore develop-docker-cocalc (was: builds well (after increasing disk image space on the Docker daemon); fails to run)
• Restore - portability-centos-7-devtoolset-gcc_11-standard (was: builds well; fails to run (exactly the same on WSL))
• Restore downstream-docker-sagemath (after Update docker build #34242)
• add github workflows that verify that sage is at least compiling in these containers. That should be relatively straightforward using https://github.com/devcontainers/ci
• improve portability-Dockerfile as explained in comment:299

Thanks! That's a beginning. Why do you not use the full build (-with-targets)?

I didn't saw the point in that. In contrast to gitpod you don't know which version of sage the developer will use in the devcontainer, especially since devcontainer are cached by vscode until they are manually rebuild.

You also don't know that on gitpod, as I've explained in #33113 comment:18

Replying to @tobiasdiez:

Sorry Matthias, but the original version of the code was working well with codespaces. I'm happy you further worked on it, but it's not fair that you introduce issues with codespaces and then say "I don't care, lets fix them in a follow up ticket".

I've set the scope of the ticket to be actionable. Work on codespaces is not actionable for me. You want to support them, you do the work on the follow-up ticket.

src/doc/en/developer/portability_testing.rst: Update references to devcontainer ...Command

[mkoeppe]

comment:299

Replying to @tobiasdiez:

So what about deleting the portability dockerfile completely

It's there as preparation for the following improvement (which is waiting for #29536):

• always pull FROM the build stage -with-system-packages
• then COPY the Sage SAGE_LOCAL (but not the old Sage source tree) from the requested build stage such as the default -with-targets
  This creates a smaller version of the container image.

.devcontainer/onCreate.sh, portability-updateContent.sh: Rename from post_create.sh, portability-post_start.sh

[mkoeppe]

comment:302

Replying to @tobiasdiez:

the names of the "post" scripts need to be changed and the docs changed to reflect the recent changes of "onCreateCommand" etc.

Thanks for catching this. Done now.

comment:304

Simple renaming. Positive again.
