As documented proxy server configuration is done in tml_zones_properties.json using the below properties:
        "mom_server_proxy_host": "",
        "mom_server_proxy_port": 3128,
        "mom_server_proxy_username": "",
        "mom_server_proxy_password": "",
        "target_server_proxy_host": "",
        "target_server_proxy_port": 3128,
        "no_proxy_pool": ""
       
This configuration is done per zone. As seen in the properties file, values have to be specified for each zone.

All Supported Platforms

Here are additional inputs on these:

- If the cluster has only one zone, please provide values under zone0.
- The IP address(es) or hostname(s) for proxy_host properties should be enclosed in double-quotes.

#When the IP address was not in quotes:
- the attachment "ML_TM-containeragent_error_incorrect_proxy-in-zones-prop.txt" has sample errors in containeragent logs
- the proxy_error.log and proxy_debug.log were empty
- the javaproxy on the container did not even start, as the final properties file was empty
/opt/mashery/containeragent/resources/properties/tml_tm_properties_final.json & tml_tm_properties_internal.json

 

This article provides inputs for configuring ML to use proxy server(s).
