Aws Issue - Port issues

• By default AWS does not open any port other then 22 for ssh.
• Also the default docket ports are 2375 and 2376.

We need to manually open the ports in the instance configuration . Else we face the following issues :

• docker swarm joining will fail as port number 2377 is not opened by default. Docker swarm init will by default create join tokens with port number 2377.
  • Services and containers which are placed on other machines in the swarm network will not be able to communicate with each other
  • We cannot access the deployed docker services with their port number from outside machines
  • Manually need to open the port numbers used by the respective services (Requires knowledge on the deployed architecture and all service port configurations)

Solution 1 : Easiest for Development purposes

• Edit Inbound rules to allow all traffic to all.

Solution 2 : Complex

• Manually set the rules.

-Even after manually setting rules, still there were some issues like the portainer and portainer-agent was not able to fetch information about containers running in other worker machines.

Conclusion : Solution 1 works like charm and everything is working as expected
