Template repository for creating images using Packer

Modifying the packer.pkr.hcl file

The packer.pkr.hcl file includes several parameters that can be modified to edit your image:

  # Modify 
  project_id   = "GCP_PROJECT_ID"                 <------- Change to your own Google Cloud Project ID

  # Modify where desired
  image_name   = "instruqt-image-01"              <------- Name Instruqt will use to reference your image
  source_image = "ubuntu-2204-jammy-v20221101a"   <------- Default is Ubuntu 22.04, but feel free to change this
  disk_size    = "10"                             <------- Disk size in Gb

Furthermore, you can edit/add your own provisioners to the file:

  # All files in the "files" directory will be copied to the image
  provisioner "file" {
    source = "files/"
    destination = "/root"
  }
  
  # The Nginx package will be installed on the image
  provisioner "shell" {
    inline = ["apt update && apt install nginx -y"]
  }

Automating this template even further

By default, this template is only configured to generate images whenever you manually run the Packer GitHub Action. You can modify the .github/workflows/packer.yml file to trigger image creation in different ways.

For example, to trigger image creation every time there is a push to the main branch, you can use the following configuration:

on:
  push:
    branches:
      - main
