MultiCloud Classroom notes 12/Aug/2025

EC2 image builder

• In EC2 image builder we build a pipeline that
  • boots a build instance
  • installs your software (via Component)
  • run tests (optional)
  • Creates a versioned AMI
  • repeatable on deman or on schedule
• Concepts
  • Component: YAML steps
  • image recipe
  • infra configuration
  • distribution
  • pipeline
• Prereqs:
  • AWS CLI
  • VPC
  • S3 bucket

First Example

• Watch classroom recording for guided creation

Azure VM Images

• Azure has two types of images
  • Generalized Image:
    • Allows to set username and password/key by removing machine specific details such as user name, hostname and security identifiers
  • Specialized Image
    • Doesnt Allows to set username and password/key
• Azure Images can be created in two ways
  • Azure compute Gallery
  • Azure Managed Images
• Azure identfies Image using urn <publisher>:<offer>:<sku>:<version>
  • publisher
  • offer
  • sku
  • version

Lets create the zayshop image in compute gallery in Azure

• Manual steps

sudo apt update
sudo apt install nginx unzip -y
cd /tmp
wget https://templatemo.com/tm-zip-files-2020/templatemo_559_zay_shop.zip
unzip templatemo_559_zay_shop.zip
cd /tmp/templatemo_559_zay_shop
sudo cp -r . /var/www/html

• Now create a new vm in a different resource group and execute the above manual steps
• Lets create a resource group for storing images
• Now lets create an Azure compute Gallery in the resource group (watch classroom recording for guided creation.)
• Navigate to vm and click on capture and provide the gallery information and other required info to create a vm image version.
