I have an application that runs on several servers in a cluster. I am looking to access container in A from many containers in A, B , C, D etc… Containers have different IP class than others obviously. I can’t even ping the Database Container from the other server. In the past I have been able to do this with a NOSQL via Nginx. Anyway looking for the easiest and best way for container 240.19.0.95 to be able to access Mysql in 240.18.0.90.
The subnets you’re using suggest you’re using a fan nework, is that correct?
If so, all containers would be expected to have direct IP connectivity to one another, if they don’t (as you’re indicating), then it’d probably be best to figure out what’s preventing the fan from doing its job, once resolved, that will allow direct connectivity between containers.
I have UFW in each server and added ufw allow proto udp from any to any port 4789 to each server. Not sure if this fulfills your rule: ufw allow proto udp from any to any port 4789
I found that if disable UFW it seems to work.
Any idea for what rule to add.
