webhook is a lightweight configurable tool written in Go, that allows you to easily create HTTP endpoints (hooks) on your server, which you can use to execute configured commands. You can also pass data from the HTTP request (such as headers, payload or query variables) to your commands.webhook also allows you to specify rules which have to be satisfied in order for the hook to be triggered.

For example, if you're using Github or Bitbucket, you can usewebhook to set up a hook that runs a redeploy script for your project on your staging server, whenever you push changes to the master branch of your project.

If you use Mattermost or Slack, you can set up an "Outgoing webhook integration" or "Slash command" to run various commands on your server, which can then report back directly to you or your channels using the "Incoming webhook integrations", or the appropriate response body.

webhook aims to do nothing more than it should do, and that is:

1. receive the request,
2. parse the headers, payload and query variables,
3. check if the specified rules for the hook are satisfied,
4. and finally, pass the specified arguments to the specified command viacommand line arguments or via environment variables.

Everything else is the responsibility of the command's author.

If you don't have time to waste configuring, hosting, debugging and maintaining your webhook instance, we offer aSaaS solution that has all of the capabilities webhook provides, plus a lot more, and all that packaged in a nice friendly web interface. If you are interested, find out more athookdoo website. If you have any questions, you can contact us atinfo@hookdoo.com

To get started, first make sure you've properly set up yourGo 1.12 or newer environment and then run

$ go get github.com/adnanh/webhook

to get the latest version of thewebhook.

If you are using Ubuntu linux (17.04 or later), you can install webhook usingsudo apt-get install webhook which will install community packaged version.

If you are using Debian linux ("stretch" or later), you can install webhook usingsudo apt-get install webhook which will install community packaged version (thanks@freeekanayaka) fromhttps://packages.debian.org/sid/webhook

Prebuilt binaries for different architectures are available atGitHub Releases.

Next step is to define some hooks you wantwebhook to serve. Begin by creating an empty file namedhooks.json. This file will contain an array of hooks thewebhook will serve. CheckHook definition page to see the detailed description of what properties a hook can contain, and how to use them.

Let's define a simple hook namedredeploy-webhook that will run a redeploy script located in/var/scripts/redeploy.sh. Make sure that your bash script has#!/bin/sh shebang on top.

Ourhooks.json file will now look like this:

[  {"id":"redeploy-webhook","execute-command":"/var/scripts/redeploy.sh","command-working-directory":"/var/webhook"  }]

You can now runwebhook using

$ /path/to/webhook -hooks hooks.json -verbose

It will start up on default port 9000 and will provide you with one HTTP endpoint

http://yourserver:9000/hooks/redeploy-webhook

Checkwebhook parameters page to see how to override the ip, port and other settings such as hook hotreload, verbose output, etc, when starting thewebhook.

By performing a simple HTTP GET or POST request to that endpoint, your specified redeploy script would be executed. Neat!

However, hook defined like that could pose a security threat to your system, because anyone who knows your endpoint, can send a request and execute your command. To prevent that, you can use the"trigger-rule" property for your hook, to specify the exact circumstances under which the hook would be triggered. For example, you can use them to add a secret that you must supply as a parameter in order to successfully trigger the hook. Please check out theHook rules page for detailed list of available rules and their usage.

webhook can parse thehooks.json input file as a Go template when given the-templateCLI parameter. See theTemplates page for more details on template usage.

webhook by default serves hooks using http. If you wantwebhook to serve secure content using https, you can use the-secure flag while startingwebhook. Files containing a certificate and matching private key for the server must be provided using the-cert /path/to/cert.pem and-key /path/to/key.pem flags. If the certificate is signed by a certificate authority, the cert file should be the concatenation of the server's certificate followed by the CA's certificate.

TLS version and cipher suite selection flags are available from the command line. To list available cipher suites, use the-list-cipher-suites flag. The-tls-min-version flag can be used with-list-cipher-suites.

If you want to set CORS headers, you can use the-header name=value flag while startingwebhook to set the appropriate CORS headers that will be returned with each response.

You can usealmir/webhook docker image, or create your own (please readthis discussion).
