Hi Shameera, Yes your suggested changes are working and I am able to run all three docker containers. regarding the containers ip, we will pass them as environment variable during docker container creation instead of linking them. Properties files values will be replaced with the env variables in the startup.
Thanks again for finding the solution. I will prepare a Dockerfile and a docker image for this.
