To start a bash prompt with only Docker installed on your host OS, run the following command:

docker run --rm -v $PWD:/src -w /src -u node -it node /bin/bash

Here's what each parameter does:

• --rm removes the container once you exit
• -v $PWD:/src will mount your current host working directory into /src inside the container

# `CMD ["/hello"]`

docker pull hello-world
docker inspect -f "{{.Config.Cmd}}" hello-world | cut -f2 -d "[" | cut -f1 -d "]"
# produces: `/hello`

A quick note on how I'm currently handling Blue/Green or A/B deployments with Terraform and AWS EC2 Auto Scaling.

In my particular use case, I want to be able to inspect an AMI deployment manually before disabling the previous deployment.

Hopefully someone finds this useful, and if you have and feedback please leave a comment or email me.

Overview

I build my AMI's using Packer and Ansible.
