Hi StarlingX Community: I have spent some time to explore how to add smaller memory node on stx system. The approach I'm trying is containerizing flocking services for worker node. And the status/achievement are * 2G memory nodes (ubuntu 18.04 and centos 7.6) were successfully added to multi-node stx system . this node is unlocked , available and joined stx k8s system. * Sysinv-agent , hbsClient and mtcClient are containerized and deploy this node . * Configuration was manually set and some device audit was bypass. There should be still a long way to fully functional worker node on such smaller memory node, such as auto-config , devices audit and other containerization services etc., The status and plan for net step is shared in [1] I created story [2] to track the change if task is ready [1] https://drive.google.com/file/d/1nt-Mx2Ebrqr4IBruSoOVmB5cjdOQ9HJR/view?usp=s...
