Deploy from Github/Travis CI to Server using Webhook API

To test the service from Github or other provider we need to have a publicly accessible server. If you already have a public webhook endpoint you can skip this step.

sudo npm install -g localtunnel

Start tunnel after the application have been started

lt --port 8080 --subdomain deploy-hook

Accessing service via deployed tunnel

https://deploy-hook.localtunnel.me/deploy

Application is written in golang so you will need that installed first.

# compile and run go run . 127.0.0.7:8787 # build executable go build # build executable and launch application go build && ./deploy-webhook 127.0.0.1:8787

Starting application

# Usage ./deploy-webhook host:port # Bind to loopback interface on port 8787 ./deploy-webhook 127.0.0.1:8787 # Bind to any interface on port 8787 ./deploy-webhook :8787

There will be couple endpoint that are eposed after the application is started

GET / : Display status of the service POST /deploy : Handle incomming payload GET /metrics : Display deployment metrics

Status request 127.0.0.1:8787

Response

Copy the sevice file deploy-webhook.service to /etc/systemd/system

JSON to GO struct conversion

https://developer.github.com/v3/activity/events/types/#pushevent https://mholt.github.io/json-to-go/

During conversion there are couple issues where we have to change some fields from int to time.Time in generated code.

Added support handling both content-types application/json and application/x-www-form-urlencoded
