I've done the following:
Created a service container using below command
docker service create -p 8181:80 --name mysvc1 ngnix
Worker node and manager node is ready.
Service is running on manager
The container is running on the manager.
EC2 instances created
Security Group configured
Nginx service is accessible from manager node public IP.
If nginx is running on manager node. Why nginx is not accessible from Swarm worker node.
