I followed the setups outlined in this document as a guide :
Once I try to bootstrap the cms using the command, docker-compose up -d, I get the following error:
ERROR: for cms-web Cannot start service cms-web: driver failed programming external connectivity on endpoint xibo_cms-web_1 (16d950adde7204ee0e9a3b50198e9ed48229a088c04225b80d349436087ddc): Error starting userland proxy: listen tcp 0.0.0.:80: bind: address already in use
ERROR: Encountered errors while bringing up the project.
I tried changing the ports using the cms_custom-ports.yml file but I keep getting the same error. I am using AWS EC2 service and Bitnami to host the server.The server is running ubuntu and has LAMP 5.6.30-2 installed.
I have been using 1.7.9 with no issue and I would like move to 1.8.1. Any help is greatly appreciated.
