Configurable nginx access logs

[tuananhnguyen-ct]

What would be the best way to configure application access logs at nginx level? We want to log both the access when passing through the managed nginx and at the application to trace the performance and for debugging purposes.

For now we could edit the nginx configmap to add logging config, for example

log-format-upstream: '{"time": "$time_iso8601", "remote_addr": "$proxy_protocol_addr",
    "x_forwarded_for": "$proxy_add_x_forwarded_for", "request_id": "$req_id", "remote_user":
    "$remote_user", "bytes_sent": $bytes_sent, "request_time": $request_time, "status":
    $status, "vhost": "$host", "request_proto": "$server_protocol", "path": "$uri",
    "request_query": "$args", "request_length": $request_length, "duration": $request_time,"method":
    "$request_method", "http_referrer": "$http_referer", "http_user_agent": "$http_user_agent"
    }'

but it is not supported and will be reconciled/reset following #139

To clarify, the default value of log-format-upstream doesn't work for our use case, as we want to collect the host name and use json format.

We will add this to the backlog.
