ABOUT

This is a Dockerized installation of Symbolics OpenGenera.

WARNING!

At the moment, this ONLY runs on Linux hosts, and does not support Docker or Docker-Machine running on OS X. I'm still working on getting that to work.

PREREQUISITES

In order to run this image, you MUST be running a relatively recent version of Docker on a 64-bit Linux host.

Additionally, the Linux host MUST have NFS support installed. It is not actually used for NFS mounting, but if NFS support is not installed on the host, the kernel that Docker uses will not have NFS support either, and NFS support is critical to getting Open Genera running.

If you get a message about NFS not being supported in the kernel, make sure you install nfs-kernel-server on your host.

BUILDING

docker build -t docker-vlm .

RUNNING

To run the VLM under Docker, please use the included dvlm utility.

For a summary of help, type dvlm -h.

In short, dvlm is a wrapper around docker that knows how to build and run new containers with the appropriate settings. It hides some of Docker's more ugly complexities.

dvlm has two commands:

• build: Build a new container

• run: Run a built container

Note that dvlm uses a hack to get X11 working. It maps the X11 UNIX domain socket directory into the Docker machine, allowing it to be shared by both your main display and by genera. If you do not have the X11 socket directory /tmp/.X11-unix, this hack will not work, and dvlm will refuse to run.

There are three options options available when building a new container:

• -g, which can point the VLM at a compiled genera binary on the local host.

• -s, which can point the VLM at a directory containing sys.sct on the local host.

• -w, which can point the VLM at a local vload world file to load.

NOTES ABOUT THE INSTALL

• The Docker image includes a Genera 8.5 world with a pre-defined Site named "Docker".

• There is only one UNIX user, named genera. You may log into Genera with the password xyzzy. This password is hard-coded. If you want to change it, edit the definition of RPC::USERNAME-AND-PASSWORD-VALID-P in nfs/authentication.lisp

• The docker VLM virtual machine is named GENERA and has IP address 192.168.2.2.

• The docker host is named GENERA-VLM and has IP address 192.168.2.1.

• NFS shares the entire UNIX root file system, as is normal with Open Genera.
