github-auto-deploy

Python webserver that listens for webhooks on a reposity and then does a pull to get latest code

forked from http://logsol.github.io/Github-Auto-Deploy/

Requires linux, apache

Project setup

Install required software

• python
• git

sudo apt-get install python git

Get Github Auto Deploy

Get a copy of this repo, store in "/opt". We can't keep this in the home dir because that is encrypted and doesn't stay running after logging out

cd /opt
git clone https://github.com/USGS-WiM/Github-Auto-Deploy.git

Start autodeploy as a background service

This command starts and keeps the service running as a background service

 /usr/bin/nohup python /opt/Github-Auto-Deploy/GitAutoDeploy.py > /dev/null 2>&1 &

Setup crontab to keep service running

This shell script checks to make sure the GitAutoDeploy.py script is running every 5 minutes

crontab -e
crontab -u ubuntu -l; echo "*/5 * * * * /opt/chkGitAutoDeploy.sh"

Add a new project to auto-deploy

1. Get initial clones of repositories to be auto-deployed

This command will get a copy of the repository that will be the base for the deployment. Run this from your home folder, ie "/home/ubuntu"

cd /home/ubuntu
git clone https://github.com/USGS-WiM/StreamStats.git

2. Set up symobolic links for apache

This creates a symbolic link between the github repository in your home folder and the apache web server home folder. Here we can specify to only make the symbolic link from a specific folder in the github reposity, ie "/dist" in the example below.

ln -s /home/ubuntu/streamstats/dist /var/www/html/streamstats

3. Edit auto-deploy configuration file

Edit the file "/opt/Github-Auto-Deploy/GitAutoDeploy.conf.json"

sudo nano /opt/Github-Auto-Deploy/GitAutoDeploy.conf.json

add an object like:

{
   "url": "https://github.com/USGS-WiM/NSS",
   "path": "/home/ubuntu/NSS",
   "deploy": "echo deploying"
}

4. Set up webhook on Github.com

On the Github page go to a repository, then go to "Settings" on the right, then "Webhooks & Services", "Add webhook" under "Webhooks." Add the url of your machine + port (e.g. http://example.com:8001). Specify Content type as application/json. Leave the event as just the push event.
