Measurement Computing has not conducted any testing using Kubernetes pods. There are no plans to do so.

Hey @anup28,

I think this should be possible if you configure the container correctly:

Out of curiosity, what are you working on needs to access the MCC hardware from K8s?

I was able to run this out of a docker container, so I assume you could do it with a cluster, although I'm also curious as to why somebody would do that.. On the host device, you'll need to map the host device inside of the container as referenced above, but also you'll need to modify the install.sh script. It calls daqhats_read_eeprom during the setup as a validation and will abort on failure, but this will never pass during your makefile execution since it requires host hardware not in place yet.

I broke out the install script to just the compilation & installation and created a startup script that will execute the daqhats_read_eeprom on boot to ensure the hats stay up to date.
