liqo : something to try on top of openEBS to test multi region, dissaster recovery etc

[Jean-Baptiste-Lasselle]

Ok let's just plan a try with this:

• https://docs.liqo.io/en/stable/features/storage-fabric.html#storage-fabric
• excellent example all fully based on KinD : https://docs.liqo.io/en/stable/examples/stateful-applications.html

the goal would be to get this :

https://docs.liqo.io/en/stable/usage/stateful-applications.html#usagestatefulapplicationsvirtualstorageclass

and basically, i would want my jupyter spawned pods to be in the local cluster, with virutal storage classes , pvc and pv, and the real storage to be inside the remote cluster. This would be really experimental.

The idea is to find out if, and how, it would be possible to provide persistent volumes to my pods, that are not coming from local-hostpath from the same cluster node... but well this eaxmple idea is very experimental we need other possibilities

ok i know what i need to test with liqo now : instead of the maradb in the examle, we want to achieve same for :

• minio, because of https://github.com/decoder-leco/plateforme/issues/7#issuecomment-2143579284
• let's also try postgres db, and mongodb
• and i'll backup restore with k8sup only jupyterhub users workspaces for now:

what im intersted in, for storage:

• abiliy to change from one cloud provider to another as smoothly as possible
• the bigger the data, the longer : the network banndwith here will definitely be the limit
