Docker Container/Image Basics

This is a basic step by step intro to working with Docker containers and Images. You should be able to follow along with your installation of docker, but be sure to change IDs/naming schemes according to your use case.

The goal of this exercise is to create a base image from the ubuntu base image that has both the jre and htop installed.

Start up an ubuntu container to modify, install htop, then exit.

docker run -t -i ubuntu /bin/bash

Get the ID of the container you just modified.

Mosh + OpenVPN = Love

Okay. Let's pretend here for a sec that you work in an office where UDP is filtered outbound, but we really want to use UDP for mosh.

Here's the plan at a high level.

1. Spin up a cloud server
2. Install Docker
3. Start OpenVPN Container
4. Grab .ovpn config
5. Modify .ovpn config to a include static route to your UDP-enabled destination

Building a new Base Image

Practical documentation on how to create a new base image.

Pick a Base Image to work on.

First we'll want to identify what image we are going to use as our base image to modify is.

In this example our previous base image is old-oca-bastion.

Define a Goal

We have been tasked with doing the following:
