Sample VNC Apptainer

This repo contains sample Apptainer recipes along with a Makefile to build one on UW Hyak Klone.

These Apptainer containers are used by hyakvnc.py to start a VNC session.

Available Apptainers:

• ubuntu20.04_min
• ubuntu20.04
• rockylinux8_min
• rockylinux8

Minimized/barebones container recipes, suffixed with _min, are provided with XFCE4, vncserver, and dependencies to run Lmod and build/run Apptainers.

Standard recipes, without any suffix, provide additional tools and libraries required for some programs.

These container recipes are provided to serve as examples and are meant to be modified to user needs.

Build Steps

Following guidance from Hyak's Documentation, We will need to build the container on an interactive work node:

salloc -A <mygroup> -p <mypartition> -N 1 -n2 --mem=10G --time=2:00:00
# connect to allocated node. Example: ssh n3300
ssh <node_name>
module load apptainer/1.1.5

Navigate to this directory then run make with the name of container specified:

cd /path/to/hyak_vnc_apptainer
make CONT_NAME=rockylinux

If successful, a container file ending with .sif can be found in the directory with the same name as the container.
