Building Docker image with Packer and provisioning with Ansible

Overview

Packer

• Packer is used to build image from a base image, perform provisions and store (commit) the final image.

• We use provisioners and Packer templates to do the actual work to create the final image.

• We use Ansible for provisioning.
