Official docker image for building openscad files?

[kasbah]

We use Gitlab CI to build the STLs for our microscope and other designs. Would be handy if we could just pull in a base image with an up-to-date OpenSCAD (openscad/openscad:latest ?) instead of that dance with Ubuntu and the PPA. What do you think?

Ah, nice. See discussion in #2, would that change already cover what you need for the CI?

[kasbah]

I am not sure, sorry. I don't understand those changes.

We just want to be able to say image: openscad/openscad:latest in our CI config and use that for our builds. Maybe something similar is already possible and I just don't know about it?

I guess it's less important for us since we already set up a working CI, but for new projects that want to set up OpenSCAD builds in CI, it could be much simpler than figuring out how to get an up-to-date OpenSCAD into another image.

(We'd also need to install Python alongside OpenSCAD but I assume that will be less fuss.)

[t-paul]

Well, it's just unfortunate that OpenSCAD fell out of Ubuntu 18.04 for totally Ubuntu unrelated reasons. It should be back in 20.04 (unfortunately we'll likely miss the deadline for getting a new release out, but 2019.05 should be there). So the normal expectation is to be able to just use apt-get install openscad. I've not tested it, but OpenSCAD is also available in the Alpine package repo for minimal image sizes.

That said, maybe having a separate base image might be still useful with tags for releases and :nightly tracking master branch builds. I'm not sure what the best base image would be, but I suspect latest Ubuntu LTS is probably the way to go.

[kasbah]

Sure, if you can just apt install that makes it easier too. I think having an "official" openscad docker image for based on alpine would still be cool. People with a little familiarity with docker will know exactly what to do with it.

Official user-facing Docker images would be great, I came across this repo and the images in https://hub.docker.com/u/openscad (by Googling [docker openscad], of course) looking for an image I could just run with.

It'd also be helpful to document in Docker Hub and the README here the purpose of these images, since I spent a few minutes trying to figure it out.

I also would like to be able to run docker run openscad/openscad:latest in a CI System.

Do none of these images provide a working openscad binary? https://hub.docker.com/u/openscad

❌ = mxe-x86_64-gui (not sure what this does?) ❌ = mxe-x86_64-openscad (creates a tarball) ❌ = appimage-x86_64-base (creates /appimage directory but there are no working binaries in that folder) 🟢 = appimage-x86_64-openscad (creates a tarball ,this could be modified to work with a modified entrypoint as shown here; however it appears that only the arm builds got pushed to dockerhub, no intel builds got pushed. 😢 )

[t-paul]

No, those images are still only meant for the OpenSCAD CI Pipeline. I'd like that to change at some point, but without help that may or may not happen in the near future.

[spuder]

Thank you. I will look into how much work it would be and try and see if I am able to contribute.

For anyone else looking to create an openscad image, you could try making your own docker container.

FROM ubuntu:20.04
RUN apt update && apt install -y openscad

docker build . -t foobar/openscad

Unfortunately the latest version of openscad in ubuntu repos is 2019.05

openscad --version
OpenSCAD version 2019.05

[spuder]

I've built my own openscad containers that work for my pipelines

docker pull spuder/openscad:latest

Documentation is available in this repo https://github.com/spuder/openscad-dockerhub

It is based off of the 2021.01 release running on official debian docker container

Images of 2019.05 and 2021.01 based on Debian Buster and dev snapshot based on Debian Bookworm are now available at:
