Hi, We can do the following changes to support backward compatibility of PCA.
1. Update new MB related values such as MB_URLS, MB-USERNAME, etc in start-agent.sh Start-agent script will read the env variables and update the agent.conf file in PCA. I have already done the fix for this in [1]. 2. As we have forked the PCA for PPaas, we will be changing that as follows. Users can send MB_URLS or can send both MB_IP and MB_PORT. PCA will give the priority for MB_URLS over MB_IP and MB_PORT. PCA will change to handle both cases. If MB_URLS are sent, PCA will export one of the successful mb ips as MB_IP for the sake of the plugin. In the plugin we need to know any of the mb ips for the initialization of the cluster. With this change there is no need of changing the plugins and template modules. If any of the users need to change the default AMQP port, they can send that from the cartridge definition. Cartridge definition property values will be exported as ENV values and those will be used with the configurator when configuring the server.
