We noticed while setting up rancher on premise, that there is no option for a rancher container to write data to an external DB (at least that’s what we understood from reading the docs) as there was in rancher 1.6.
My question is - where is all the data being saved ? i realize the rancher container starts up a local DB, but what will happen when i’ll try to set up an HA rancher environment ?
what DB will store all the pods’ data ?
how will all the data sync between the pods ?
I’ve read the docs about installing rancher in HA - https://rancher.com/docs/rancher/v2.x/en/installation/ha/
and also looked through the helm chart - https://github.com/rancher/server-chart
and couldn’t find anything.
