LoadRunner - GitHub Webhook Server and Event Simulator
LoadRunner is a multi-purpose utility for working with GitHub webhooks and statuses.
It provides these features:
- A webserver that responds to GitHub webhook events and can run any arbitrary script written in any language.
- A command line utility for testing your webhook server configuration by sending simulated events.
- A command line utility for sending status updates to pull requests.
Install
$ gem install loadrunner
Getting Started
- Download the handlers directory from this repository, as an exmaple. This directory contains several handler examples.
- Make sure that all files within that folder are executables.
- Start the server (from the
handlers
parent directory):loadrunner server
- In another terminal, send a sample webhook event: `loadrunner event localhost:3000/payload myrepo push master
The server should respond with a detailed JSON response, specifying what
handlers were executed (executed_handlers
) and what handlers could have
been executed, if they were defined in the handlers folder
(matching_handlers
).
For more options, see the [documentation][1] or run
```shell
$ loadrunner --help
Building Handlers
When running the server, it will look for handlers (executable scripts) in
the ./handlers
directory, using one of these format:
handlers/global
handlers/<repo name>/global
handlers/<repo name>/<event type>
handlers/<repo name>/<event type>@branch=<branch name>
handlers/<repo name>/<event type>@tag=<branch name>
For example:
handlers/global
handlers/myrepo/global
handlers/myrepo/push
handlers/myrepo/push@branch=master
handlers/myrepo/push@tag=release
When none of the handlers are found, LoadRunner will respond with a list of handlers it was looking for, so you can use this response to figure out what it needs.
The handlers can be written in any language, and should simply be executables.
Environment Variables
These environment variables are available to your handlers:
LOADRUNNER_REPO
LOADRUNNER_EVENT
LOADRUNNER_BRANCH
LOADRUNNER_REF
LOADRUNNER_TAG
LOADRUNNER_PAYLOAD
- the entire JSON string as received from GitHub, or the client.
Running with Docker
You can run both the server and the client using Docker.
# Server
$ docker run -p3000:3000 dannyben/loadrunner server
# Client
$ docker run dannyben/loadrunner event http://webhook.server.com/payload repo push
If you wish to connect the client to the server you are running through Docker, you can do something like this:
$ docker run --network host dannyben/loadrunner event http://localhost:3000/payload repo push
