CI/CD Resume

• This is a trivial setup to demonstrate CI/CD
• We do realize this is not how CI/CD works in real organizations
• This project tries to demonstrate the important concepts

Concepts demonstrated

• Github push triggering a CI/CD
• There is no CI here since there is nothing to build
• CD is triggered using a webhook which deploys to a digitalocean droplet

Components in CI/CD pipeline

• Github
• webhook
• Digitalocean droplet (this is what hosts the resume)

What exactly happens in the pipeline

• The resume is just a html document with CSS
• Digitalocean droplet is running a docker host on ubuntu
• We are running a NGINX docker container which serves our static website

• we have mounted the folder containing resume on the docker container as a volume
• so whenever we change the resume.html on docker host nginx container serving the content will get the updates

• We have installed a webhook receiver on the digitalocean droplet to receive webhooks
  • The webhook on the droplet is configured to download the raw resume html on receiving a webhook and replacing the existing resume.html on docker host
  • once this html on docker host is refreshed the same change will make it to the container
• We have configured github to send a webhook on every push or commit to github

Pipeline in action

• Change is pushed to Github
• Github triggers a webhook on digitalocean droplet
• Upon invoking, Webhook downloads the latest resume.html from github and replaces the old content
• As soon as the html is refreshed, it makes its way to the container
