This code has the simple mission of receiving a payload via HTTP 1.1 on any URL and place the content body in a pubsub topic.
The webhook will listen to any url path and HTTP method (GET, POST, PUT, ...). As long that there's a body, the message will be sent to Pubsub. All the http message headers will be added in the PubsubMessage attributes, also 'request-path' and 'request-method' will be added with the path and method information.
The service account associated with the service that runs the container will be checked for permission pubsub.topics.publish on the configured topic before it starts to listen to HTTP calls. If the container fails to start the webserver, please check the logs because this is a possible reason of the container failing to start.
