WebhookMQ

Receive webhooks and put them into a message queue.

Built in python using Django for web requests and kombu for message queue handling.

Message queues supported

The kombu library supports amqp, qpid, redis, mongodb and more: http://kombu.readthedocs.org/en/latest/userguide/connections.html

Webhooks supported

Note that this app has no security. Any POST request to an endpoint using the right path prefix will result in an attempt to put a message on a queue, as long as request contents can be decoded as JSON or a key-value multipart/form-data.

The way to avoid abuse is to restrict access to this app in a firewall and validate message contents when consuming them from the queue.

http(s)://hostname.example.com/path/queue_name

On a successful request, HTTP 200 OK is returned. On some errors, content returned will be a JSON structure with a 'message' key.

Build

Either pull an image automatically built from this repo (https://hub.docker.com/r/stanislavb/webhookmq/):

docker pull stanislavb/webhookmq

Or build your own:

make build

Test

Test code standards (requires flake8 installed):

make syntax-test

Test integration with RabbitMQ:

make docker-integration-test

Bring the service up locally and try POSTing to it.

docker-compose up -d
# If running Linux:
curl --data "param1=value1&param2=value2" http://localhost/test/foo
# If running OSX with docker-machine:
curl --data "param1=value1&param2=value2" http://$(docker-machine ip $DOCKER_MACHINE_NAME)/test/foo

Deploy

Hosting of a message queue is not covered by this document, but if you have one provisioned, you can scale WebhookMQ horisontally just by starting more with same settings.

docker run -d \
    -e "SECRET_KEY=foo" \
    -e "PATH_PREFIX=webhook" \
    -e "MQ_URI=amqp://user:password@mq.example.com/vhost/" \
    stanislavb/webhookmq

The command above would start the service and accept POST requests at http://(container ip):8080/webhook/(queue_name)/

Use nginx proxy

It is extremely recommended to use a robust web server in front of any web application. You could for example use jwilder/nginx-proxy:

docker run -d \
    --name nginx-proxy \
    -v /var/run/docker.sock:/tmp/docker.sock:ro \
    -p 80:80 \
    jwilder/nginx-proxy

docker run -d \
    -e "SECRET_KEY=foo" \
    -e "PATH_PREFIX=webhook" \
    -e "MQ_URI=amqp://user:password@mq.example.com/vhost/" \
    -e "VIRTUAL_HOST=public.example.com" \
    stanislavb/webhookmq

Provided DNS record for public.example.com would be pointing at this docker host machine, the service would accept POST requests at http://public.example.com/webhook/(queue_name)/
