I’m running Docker on Ubuntu server; around 50 containers running, most admin via Portainer. Configuration files and small databases for container applications are stored on the local SSD, media and larger files are stored on a NAS.
NAS data and the container folders are backed up.
I have a second identical machine doing nothing. What would you recommend researching to add resilience to this setup? Top priority is quick and easy restoration should the SSD fail - everything else is relatively easy to replace.
I’ll create an SSD RAID but I like the idea of a second host.
Learning K8s is a lot to take on, but it will pay off as your needs expand in the long term — and if you decide to go into infra/ops at work.
