Virtual Labs presentation at the HubLinked meeting in Dublin

We have participated to the HubLinked workshop in Dublin this week, where I delivered a presentation on some of our efforts on Virtual Labs, in the hope that this could be useful to the partners designing the “Global Labs” where students will experiment together for Software Engineering projects.

In this presentation (PDF) I introduced our partners to the Labtainers and Antidote Open Source projects, which are quite promising for designing “virtual labs” using VMs and/or containers.

Thomas and I have recorded the speech, and I’ve used obs and kdenlive to edit the recording.

Here’s the results (unfortunately, the sound is of low quality):

Feel free to comment, ask, etc.

Labtainers in a Web desktop through noVNC X11 proxy, full docker containers

Here’s another recording of a demo I’ve made of our efforts on running Labtainers with a Web desktop.

This time, we’re using a modified version of DoroWu’s noVNC X11 wrapper container (“docker-ubuntu-vnc-desktop“), to provide an X11 Display to labtainers.

I initially adapted DoroWu’s container image by using Debian instead of Ubuntu, but it appeared that noVNC 1.0.0 was a bit too old in the Debian package. So I switched back to the same version as the one DoroWu chose, and this time no more disconnections.

Also, we’re now rebuilding the Labtainer master container from upstream’s Git repo. Fresh Labs every day 😉

Two demos of programming inside the Web browser with Theia for Java and PHP, using Docker

Theia is a Web IDE that can be used to offer a development environment displayed in a Web browser.

I’ve recorded 2 screencasts of running Theia inside Docker containers, to develop Java and PHP applications, respectively using Maven and Composer (the latter is a Symfony application).

Demo of displaying labtainers labs in a Web browser through Guacamole

Here’s a first report on trying to add Guacamole to Labtainers in order to allow running Labtainers in a headless way, without an X display, in containers, and accessing the GUI in a Web browser, through the use of VNC and Guacamole.

We’ve casted a demo of it :
