Ubuntu 20.04 Base Image Builder

The creation of a base image is a critical first step in building a customized and efficient cloud computing environment. This article introduces a streamlined process for creating a base image for Ubuntu 20.04, particularly designed for ARM-based virtual machines on AWS.

Understanding the Base Image Concept

A base image is essentially a foundational image from which all other images are derived. For Ubuntu 20.04, a well-crafted base image includes essential tools like zshell (zsh), oh-my-zsh with powerlevel10k, docker, docker-compose, and docker configured without sudo requirements. Automating the setup of these components simplifies the process significantly, enabling a quick start with a single script​【oaicite:2】​.

Bridging the Gap for ARM-based VMs on AWS

The motivation behind this project was to address the need for ARM-compatible Amazon Machine Images (AMIs). Traditional x86_64 AMIs are incompatible with ARM-based VMs, necessitating a new approach to build an ARM AMI for Ubuntu 20.04. This script fills that gap, streamlining the creation of ARM AMIs, ensuring compatibility and efficiency on AWS cloud infrastructure​【oaicite:1】​.

Making Cloud Deployment More Efficient

By using the provided script, users can save significant time in setting up their cloud environment. This automation is particularly useful for deploying Docker builds into AWS Elastic Container Registry (ECR), which offers additional features like image scanning for vulnerabilities. The script aids in creating secure systems, focusing on actual security rather than just vulnerability management​【oaicite:0】​.

In conclusion, the Ubuntu 20.04 Base Image Builder script serves as a valuable tool for developers and system administrators working with AWS, particularly those utilizing ARM-based VMs. It exemplifies efficiency and security in cloud computing, offering an automated solution for creating robust base images.
