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.

    You can use docker swarm (or a better container orchestrator) to have the containers automatically fail over to the second host

        Thanks. That means I need to move all data off the hosts on to, say, a NAS - then the NAS becomes the single point of failure. Can I operate a swarm without doing that but still duplicate everything from host 1 to host 2, so host 2 could take over relatively seamlessly (apart from local DNS and moving port forwarding to nginx on the remaining host)?
