You want a Docker container that runs a script and responds to requests it receives, and an address that it can receive data at, is that correct? That sounds like an HTTP server. You should configure a Docker container with the appropriate scripts, give it the ability to respond to HTTP requests, upload it to a container registry (AWS, DigitalOcean), and then run it on a container service (e.g. AWS ECS). You'll then be provided an IP address that you can issue requests to.
