Cloud Live QA

Take any Linux box or vm and convert it into a Docker-powered system to spin up new QA environments for each branch, pull in changes anytime the branch is updated, and delete the environment when the branch's pull request has been merged.

Installation

Pre-requisites:

• Ubuntu 18+, 20+
• Docker, Docker-Compose, and Git installed
• Wilcard second-level domain DNS pointing to this system

Instructions:

1. Copy the files from this repository into the system root. It would look like /docker and /hooks, respectively.

2. Create the global network that each environment will use to give subdomain access:

   docker network create nginx-proxy
   

3. Start the main Docker NGINX/SSL process:

   docker-compose -f /docker/nginx.docker-compose.yaml up -d
   

4. Setup the git repository

   mkdir /docker/repo
   git clone https://[GITHUB_USERNAME]:[GITHUB_TOKEN]@github.com/[GITHUB_REPOSITORY] /docker/repo
   

5. Install Webhooks package and configure script permissions

   sudo apt-get install webhook
   chmod +x /hooks/scripts/new.sh
   chmod +x /hooks/scripts/sync.sh
   chmod +x /hooks/scripts/delete.sh
   

6. Start Webhooks

   # Run in the background
   /usr/bin/webhook -hooks /hooks/hooks.json > /dev/null 2>&1 &
   
   # Run in debugging mode
   /usr/bin/webhook -hooks /hooks/hooks.json -verbose
   

Usage

With Webhooks running, you can reach the API through http://[YOUR_DOMAIN]:9000. Here are the endpoints you can use:

• New Environment

   POST: /hooks/new
   JSON: {
   	"pr": [PR_NUMBER]
   	"branch": [BRANCH_NAME]
   	}
  

• Update Environment

   POST: /hooks/sync
   JSON: {
   	"pr": [PR_NUMBER]
   	}
  

• Delete Environment

   POST: /hooks/delete
   JSON: {
   	"pr": [PR_NUMBER]
   	}
