Backdoor

It is a very simple service meant to be used as a web hook for deploying something via web hooks from CI in a TRUSTED ENVIRONMENT. It has only basic security built in, so it should not be used in anything you are not willing to sacrifice.

Use case

You have CI job that builds image "username/service" and pushes it to some registry. After push is done, CI fires up curl like this:

curl https://your.url/deploy/deploymentname?secret=NotSoSecretAtAll

Which hopefully pulls and deploys your newly built service.

Configuration

You need to configure at least one deployment for service to be usable. Deployment is specified in configuration file as an object with a name and two properties (script name to be executed and a secret to authorize deployment).

Here is an example of config.json file:

{
  "deploymentname": {
    "secret": "NotSoSecretAtAll",
    "script": "deploy.sh"
  }
}

When run service will read this config and and begin listening on port 8080 for requests. It will handle only requests to /deploy/{deployment} paths, where {deployment} is one of the deployment names configured in config.json. In our example above, the only working url would be /deploy/deploymentname. Then service will check secret token you passed as url value to match the one configured. If it matches, then the configured script will be run. It should exist in ./scripts directory (relative to service working dir) and be executable. If script's return code is zero, service will return HTTP code 200, otherwise code will be 500.
