SageMathCloud docker image!

[William Stein]

Hi,

For a long time people have asked for a docker SageMathCloud image, so
to start your own private SMC install would be very, very easy. Today
I made such a docker image.

https://hub.docker.com/r/williamstein/sagemathcloud/
https://github.com/sagemathinc/smc/tree/master/src/dev/docker

This may be exciting to some people!

Of course, there are surely still issues...

Thanks for this.

I want to try this today on a Debian in a virtual machine.

Is there a doc explaining how to launch the SMC server locally ?

In the mentioned github repository is a README.md file. That explains
all this to you.

except that nothing about OS is said:

The OS has to support Docker.  So most any recent version of Windows, OS X, and Linux.

potentially of interest:

"might want to check out quay.io as a hosted docker container build service, it says it has "unlimited storage and serving of public repositories" at https://quay.io/plans/. Not sure if that extends to building open source containers (or how their time limit and auto-building setup compares to docker hub), but it may be worth trying. Travis CI uses it for their docker containers."

OK, I tried it and I do find it exciting. Thanks!

I wanted to be able to install SageManifolds in the SMC docker image. To do this I needed to get root access to the SMC docker image. If you are a regular docker user perhaps this is obvious but I thought that for other people like me I would mention how I did this:

wspage@suse:~> docker ps
CONTAINER ID        IMAGE                        COMMAND                 CREATED             STATUS              PORTS                                           NAMES
7141c3e867cd        williamstein/sagemathcloud   "/bin/sh -c ./run.py"   2 days ago          Up 2 days           0.0.0.0:32769->80/tcp, 0.0.0.0:32768->443/tcp   admiring_pasteur

wspage@suse:~> docker exec -it 7141c3e867cd /bin/bash

root@7141c3e867cd:/# export TERM=xterm

Replace '7141c3e867cd' above with the container id on your system.

After a few false starts and a couple of missing dependencies I managed to build Sage 7.3 from source and then installed SageManifolds. Now I can run my Jupyter SageMantifolds worksheets on my local SMC.

I do have a question.

How can I change the project quotas?  Is there some command that I can use to give myself more resources?

[William Stein]

Awesome to it worked!   The quotas are not enforced in any way so just ignore them.

Well um, something is killing my terminal sessions (and maybe the
worksheets too, I am not sure yet) in after about an hour. I assumed
that it is because of the idle timeout.

Oops -- idle timeout is the one quota that is implemented. I've added
directions here

https://github.com/sagemathinc/smc/tree/master/src/dev/docker#make-all-users-admins

about how to make your user an admin.

Perfect. Thanks.

[William Stein]

Hi,

I've updated the free local Docker SMC build here

https://github.com/sagemathinc/smc/tree/master/src/dev/docker

and also pushed a new image to Docker hub (actually -- I started it
now -- it could take an hour to finish). The main changes are to
make things much more secure, in case you want to host several users
or a class:

- the database password is a random 63 character string now, that
users can't see.
- the umask defaults to 077 so user files are only visible to themselves.

Also, I updated all the code for SMC to the latest, which has all the
newest improvements, e.g., avatars at the projects and files level,
new version of Codemirror, better sync, etc.

Thanks again.

I have a question about using the docker image for development and
testing. Does it make sense to use docker to help with development?
Suppose I clone the smc repo, create a branch, make some changes
locally and then in src/dev/docker/

$ make build
$ make run

If I understand correctly this should give me a reasonably good way to
test my changes locally. If I like what I did, then I could just
commit, push my changes and make a pull request. Does that sound OK?

--

BTW, here is another note for people like me who are less familiar
with using docker: Rather than using a random port assignment (-P) and
leaving the terminal attached to the container as suggested in the
README.md, I prefer to create the smc container like this:

$ docker run --name=smc -v ~/smc:/projects -d -p 8080:80
williamstein/sagemathcloud

This gives the container a name (smc), detaches the terminal and
assigns local port 8080 for http (you can use a different unused port
and also assign another port for https). The name makes it easier to
refer to the container and to use commands like:

$ docker stop smc
$ docker start smc

Yes.  Also you can do dev through a project in your docker container as explained in dev/project.

Send a PR updating the readme with the above!

Thanks for this major update. It's time form me to use it with my young students.
