What have you tried, and why doesn't it work?

07/29/2022, 1:19 PMI tried making a VS Code workspace essentially (dockerized container that VSCode uses automatically) so that I could do easier remote dev, but I was very new to Pants and it failed for some reason.
However, in thinking about it, I don't know why it shouldn't work if you use pants as an entrypoint..
... Will experiment and be back shortly

07/29/2022, 1:24 PMThank you for your help. For now, I'm still figuring out what is the best way to run my tests with Pants in Concourse CI so I haven't start anything yet...

07/29/2022, 1:25 PMAh, okay - I'm running some ideas right now, this is a problem I needed to solve a while ago and completely forgot!
I'll report back if I get anywhere useful

07/29/2022, 1:38 PMok, turns out previous me might just have been a simpleton - it works fine just doing the most obvious stuff.
git clone git@github.com:pantsbuild/example-python.git Copy code
FROM python:3.9-bullseye
WORKDIR /app
COPY . /app
CMD ["bash"]docker run image-name /app/pants lint ::🙌 1

07/29/2022, 1:44 PMIf there is a good docker pattern, might be worth having some official Docker images for those teams who use docker to keep their devs in sync.
I have a bunch of Dockerfiles I use against my source working directory (as a volume) or just use as full blown dev environments, and it can streamline a lot of headaches on Mac (building the Linux kernel, anyone?)

07/29/2022, 3:19 PMHi! I am currently exploring whether we can make Pants work as a standalone binary. It’s interesting

07/29/2022, 5:08 PM@wide-midnight-78598 The problem I see with this Dockerfile, is that it bootstraps Pants every time you run a command...

07/29/2022, 5:08 PMthis may help:
https://gist.github.com/asherf/a71eba185c900f47b82007470dc377d1
There are basically 3 files, pants bootstrap script and a docker file used to prepare pants in the container during the container build process.
and a modified lightweight pants script (that should be in the repo) that will use that bootstrapped version and will break if it is not there.
Hope it helps.

Previously when I tried something like this, errors were thrown What Asher did was what I was recommending. Essentially, cache all that setup. I was also recommending creating a volume to cache the results of the lockfiles being downloaded and installed too, so that way you can save a step (probably less of a concern in CI?)

07/29/2022, 5:26 PMOk, sorry for my misunderstanding. By caching, I thought you meant caching the results of process execution...
