Agenda

  1. What is a machine image?
  2. Why should you care? 
  3. Baking vs frying
  4. Packer basics
  5. Let's build an image together

(Virtual) Machine Image

  • Snapshot of a pre-configured virtual machine
  • A blueprint to launch identical VMs

Benefits

  • Faster boot times
  • Reproducible builds 
  • A big step toward immutable
    infrastructure

Baking vs Frying

Reference: http://if.andonlyif.net/blog/2012/10/baked-servers-vs-fried-servers.html

Building an image

  1. Take an existing VM image
  2. Launch a new instance from that image
  3. Make your changes
  4. Save your VM as a new image
  5. Rinse and repeat

Packer is a tool for creating machine and container images for multiple platforms from a single source configuration.

Thanks!
