Microservice Public Proxy

Acts as a firewall-proxy between world and microservices. Exposes only specified endpoints, even is able to filter by JSON payload.

Example case:

• You have a http://10.0.1.1:8000/search/{query} endpoint and you want to expose it, but only on specified payload content

{
    "type": "_@mpp_match((article|event))"
}

Let's assume your application accepts type with values "article", "event", "users" but you want to expose only article and event - our firewall will do this for you and block unexpected values in this field.

Configuration

Put your configuration files inside of config directory, they will be automatically loaded if the extension will be ".xml"

Structure

Config -> Match: There you can define routing rules, so the firewall will know on which domains and paths to rewrite the url and possibly parse the payload.

<?xml version="1.0"?>
<definition>
    <config>
        <match type="regexp" pattern="http\:\/\/services\.example\.org\/users\/profile\/view\/(.*)" target="http://127.0.0.1:8002/users/profile/view/$1"/>
    </config>

    <payloads>
        <payload type="json">
            {
                "id": "_@mpp_match(*)",
                "type": "_@mpp_match((user|group))"
            }
        </payload>
    </payloads>
</definition>
