Hi
Environment:
Docker Version : 18.06.1 CE
Compose : 1.21
Swarm Cluster: 3 Node Swarm Cluster.
Issue:
We have a 3 node setup with Swarm. For some reason the Containers which are up in a perticular node are not able to Ping / Curl to the HOST IP in which they are setup. If i try ping / curl to other node IP’s in my swarm cluster they are pingable.
We have similar setup in other VM’s they are all working fine. We are not able to figure out the reason for the same. Can some one please help.
Did any one of you face this problem before… ?
