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.

# Capistrano configuration
# 
# require 'new_relic/recipes'         - Newrelic notification about deployment
# require 'capistrano/ext/multistage' - We use 2 deployment environment: staging and production.
# set :deploy_via, :remote_cache      - fetch only latest changes during deployment
# set :normalize_asset_timestamps     - no need to touch (date modification) every assets
# "deploy:web:disable"                - traditional maintenance page (during DB migrations deployment)
# task :restart                       - Unicorn with preload_app should be reloaded by USR2+QUIT signals, not HUP
