I’m going to install an application on a Data Center, my customer is providing me 2 physical servers for redundancy where implement our application.
All the infrastructure is redundant (2 switches, 2 firewalls, 2 power lines, 2 uplinks, 2 access to NAS).
My intention was to use Docker Swarm and run application in a docker for HA, but having only 2 phys servers I read that if one server fails we loose Manager quorum and application could not be moved to the healthy node even if it’s available.
Is it a way to overcome that with 2 physical nodes ?
Usually having 2 independent HW is enough for having a basic HA, wondering that’s not enough for Docker Swarm.
Thanks in advance.
