I have few docker nodes that are running in swarm mode. I’d like to archive followings (if possible):
- high availability
- load balancing
Let’s say one of the swarm node goes down for whatever reason, I would like to continue serving my users with my applications…
I know at least some of it is available through service, however I’m still a bit unclear on IP traffic. If host is down, how is IP traffic going get routed to another host and so on…
Let’s say I have DNS A record pointing to IP address 220.127.116.11 and if that same IP address is assigned to one of docker node host and host goes down, my assumption is that my application will be unavailable at that point… Is there a solution for that scenario?
