How to i run a sagecell server on docker?

[wj Chan]

Hey, i want to know if its possible to dockerise a sagecell server? 

[Andrey Novoseltsev]

Are there things that cannot run on Docker??? I can't easily do it as I have no Docker experience, but for those who do it should be straightforward. You can check the script that builds LXC containers if it is useful.

> script that builds LXC containers

Hey, was wondering which script this would be referring to?

I'm currently referring to a few sources

https://github.com/sagemath/sagecell says that I can create my own server
sagecell/contrib/vm at master · sagemath/sagecell (github.com) also says that I can create my own server.

The docker image at dockerhub doesn't seem like what i'm looking for, was wondering if anyone else on the Sagecell team can chime in on the feasibility?

[Andrey Novoseltsev]

This script

https://github.com/sagemath/sagecell/blob/master/contrib/vm/container_manager.py

creates LXC containers with SageMathCell running inside, as well as manages HAProxy on the host machine to serve those containers.

I've made some progress following the instructions on  sagemath/sagecell: The Sage Cell Server---providing a way to embed Sage computations into any web page. (github.com)
I'm having an issue with the Makefile, it assumes a sage-root, which ends up being the sage/ directory i cloned in earlier instruction. 

 cp: can't stat '/sage/local/lib/python3.9/site-packages/notebook/static': No such file or directory

Where should sage-root be pointing to?

[Andrey Novoseltsev]

I don't point sage-root anywhere - if you run make from within the Sage shell, it is detected automatically. Current master branches were successfully deployed on public servers, so no errors with paths are expected.

Hi, sorry for the revived thread. I have managed to dockerise the server, but would like to ask, is it possible to remove the internet restrictions, and how?

I'm already hosting the server on the client end, unless I'm misunderstanding something I would like to "whitelist" all sites, aka remove the internet access restrictions.

[Andrey Novoseltsev]

There is a firewall script in the root directory, if you don't want any restrictions - remove it from the systemd script!

Hi, in terms of your instructions here (https://github.com/sagemath/sagecell), not running on the VM:

git clone https://github.com/sagemath/sagecell.git 

pushd sagecell 

git submodule update --init --recursive

 ../sage/sage -sh -c make

is it possible to remove the firewall rules at this point? Or anywhere in web_server.py?

[Andrey Novoseltsev]

If you are following simple instructions, there are no firewall rules whatsoever, they are implemented completely independent on SageMathCell code itself. However, I would strongly advice against using such a setup in anything exposed to the outside world - by design it is possible to run arbitrary code...
