Tip: The services running in the custom docker images in WSO2 Integration Cloud can only be exposed via ports 80 and 443.
The custom docker image routes traffic through one pair of ports from (9763,9443), (8080,8443), and (8280,8243). Traffic from port 80 goes through the first port in the pair while traffic from port 443 goes through the second. At the moment, you do not have support to use any pair of ports in the docker images
If you want to configure a port that is not listed above, please contact us via the Support link in WSO2 Integration Cloud.
