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

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.

	#!/bin/bash -e

	# Using the "hello-world" image as an example
	# https://github.com/docker-library/hello-world/blob/c83a065a24e94e635ddd518c2a3cffc91accf30d/amd64/hello-world/Dockerfile#L3
	# `CMD ["/hello"]`

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

	#!/bin/bash

	# set pw to the password you want to lookup (of course, be careful with writing this to your shell history or unencrypted disk!)
	pw="insecure"

	# this will output the number of times it has been pwned
	s=$(echo -n $pw \| openssl sha1 \| tr '[a-z]' '[A-Z]'); curl -s "https://api.pwnedpasswords.com/range/${s:0:5}" \| grep "${s:5}" \| cut -d ":" -f 2

	#!/bin/bash -e

	# sentry_event params: [event_id] [culprit] [message] [optional:extra]
	sentry_event() {

	# Get current unix timestamp
	TIMESTAMP=`date +%s`

	# Parse DSN
	TEMP=`echo $SENTRY_DSN \| cut -d '/' -f3`

	public class Example1 {
	public static void main(String[] args) {
	int a = 0;
	if (a >= 0) {
	System.out.println(">= 0");
	if (a != 0) {
	System.out.println("!= 0");
	}
	} else {
	System.out.println("< 0");

	MD_FILE="README.md"
	TMP_FILE=$(mktemp); pandoc $MD_FILE > $TMP_FILE; open -a "Google Chrome" $TMP_FILE && rm $TMP_FILE
