captainhook is a generic webhook listener
This tool was built as part of a CI orchestration process, to be called when Docker trusted builds finish. It explicitly ignores the posted data from the webhook because that would be `insecure`, which is `bad`.
Despite our intended purpose, it can be used to trigger any process when you receive a post to a specific URL. That's why we called it a generic webhook listener.
To use captainhook, first create a directory to store the json scripts that describe your orchestration. We'll refer to that directory as `configdir`.
Each script you create in the `configdir` will be executed when the corresponding endpoint is called.
Now add a json file in the `configdir`. There's a sample in the `example` directory with some sterile commands that won't modify your filesystem.
Run captainhook with a command similar to this:
`captainhook -configdir ~/captainhook`
If you have a script called `deployBigApp.json` you would trigger it by posting to http://your.captainhook.url/deployBigApp.
The scripts in the json file are executed sequentially, and the output is logged and returned to the caller in the response, which always has an HTTP status code of 200 (OK) even if your scripts didn't work. This is intentional, to avoid causing errors in external services like Docker or Github, which might not like you returning statuses other than 200 (OK).
