Simple Docker Hub webhook endpoint that runs a deploy script upon request

This app consists of an http-kit server that listens for incoming requests on port 8080.

It checks:

1. That the request came from Docker Hub servers between 162.242.195.64 and 162.242.195.127
2. The token query parameter in the request matches the DOCKERHUB_TOKEN environment variable

If these checks pass, it executes a shell script in the container at /dockerhub-webhook-listener/rsc/deploy.sh (if available)

Docker is included in the image, so if you mount the Docker socket when running the container, you will have access to the host Docker daemon & can issue Docker commands from within deploy.sh.

Example showing shell script & docker socket mount:

docker pull zoondka/dockerhub-webhook-listener
docker run -d -p 8080:8080 \
           -v /path/to/dockerhub-webhook-listener/rsc:/dockerhub-webhook-listener/rsc \
           -v /var/run/docker.sock:/var/run/docker.sock --name dockerhub-webhook-listener \
           -e DOCKERHUB_TOKEN=$TOKEN \
           zoondka/dockerhub-webhook-listener
