I hesitate a bit about changing the development and packaging process this much. Is there a strong reason to switch CI and/or local builds to use Docker?

Are you hitting specific issues with local development otherwise? Perhaps it helps to raise those issues first, before changing things too much.

Generally speaking, giving contributors multiple conflicting paths for development is a bit confusing, so worth being careful here.

docker-entrypoint.sh

You should be running npm run dev for development, not npm run build. build is for building the minified JS/CSS files, where dev runs Webpack development server and takes care of hot reload of the assets.

+If you have Docker available on your platform, you can get started building CSS and JS artifacts a bit faster and won't have to worry about any of the setup spilling over into your general environment.

+When building with Docker, we create an image containing the build dependencies, such as `SASS`_ , `Wyrm` and `Webpack`_ in the anticipated versions. Some of these are quite outdated and therefore ideal to isolate a container. The image is tagged as ``sphinx_rtd_theme:latest``.


This is true without Docker as well, everything is installed via NPM. Just to be clear to the contributor, I think this should be removed.

When building with Docker, we create an image containing the build dependencies, such as `SASS`_ , `Wyrm` and `Webpack`_ in the anticipated versions. Some of these are quite outdated and therefore ideal to isolate a container. The image is tagged as ``sphinx_rtd_theme:latest``.

Since the Node version and Python versions expected for the build environment weren't previously made explicit, this comment felt very spot on :) I would always advocate having a Dockerfile in order to manifest the build environment. Not trying to make it mandatory, though, that's why it's just an additional development suggestion.

This seems like a change for the contributing doc instead. The docker environment isn't going to be any different than the current build environment.

+    $ make docker-images      # Builds an updated version of the docker image
+    $ make docker-run         # Runs the docker environment and builds the assets. The container exits after completing the build.
+    $ make docker-copy-assets # Copies out the assets from the most recent docker-run


This process doesn't quite feel ready for contributors, it's a bit more complicated than the normal development pattern. Is there a reason to not just mount this path as a volume?

This should be Python 3, we don't want to support Python 2 anymore

Please see #1311

Yeah, I already commented there as well. Python 3 is supported currently, Python 2 is not required and might be documented as not support at all even.

This is not true AFAICT. We are using a version of node-sass that uses a version of node-gyp that doesn't support Python 3. I finally hit the same issue in bourbon-neat and gave up, since Wyrm didn't allow an upgrade. See #1311

The theme has been building on Python 3 for some time. This PR has passing builds for all Pythons: #1316

I haven't found an explanation for that TBH, but I'm sure it's good :) When I change the Dockerfile to use FROM python:3-alpine, I start getting errors that I never resolved, but I really did try to do it without touching our node stack. The "internet" seems to have similar issues.

sass/node-sass#2877
nodejs/node-gyp#1687

Odd, the errors don't necessarily surprise me, but I certainly can't offer an explanation. node-gyp apparently has python 3 support since 4.0.0 -- I hit this issue back in #771 -- #771 (comment)

We figured this out, or at least it's a little more clear why building on python3 image is not working. Seems Alpine is somehow using Node 18 and also cannot find the /usr/bin/python3 binary (or Alpine's python package only installs a /usr/bin/python binary

Noted already, but the node orb should be used here instead of Docker.

This is now replaced with a CircleCI env that builds our Docker image like we specify and it doesn't take a lot of build time 👍

agjohnson · 2022-08-17T17:52:42Z

Also, I should note that I raised issues on this PR, but I think there are simpler alternatives to this and it is probably more helpful to discuss some build/development issues before going too much further.

Build with Node 14 installed through orbs. Fixes readthedocs#1275

This introduced syntax errors that were not picked up in review, the `:not()` psuedo selector can't lead a selector in SASS.

agjohnson · 2022-08-17T19:10:13Z

I addressed issues with CI building in #1314, issues with a merge error in #1315, and dependency issues with #1316

benjaoming · 2022-08-17T22:42:07Z

For the record: This approach worked fine and builds were ✔️. I'd like to contest that Dockerized build environments are the way forward 😉

agjohnson · 2022-08-18T00:07:39Z

From chat, I think this PR should still continue as an additional piece to local development. This seemed close, but using Python3 and Node 14 would be issues to resolve.

I would still hold off on altering local development workflow or our CI builds though. Switching to Docker has side effects that require a bit more consideration, and we'd rather avoid disparate development workflows for now.
