Geodesic

Geodesic is the fastest way to get up and running with a rock solid, production grade cloud platform built entirely from Open Source technologies.

It’s a swiss army knife for creating and building consistent platforms to be shared across a team environment.

It easily versions staging environments in a repeatable manner that can be followed by any team member.

It's a way of doing things that allows companies to collaborate on infrastructure (~~snowflakes~~) and radically reduce Total Cost of Ownership, along with a vibrant and active slack community.

It provides a fully customizable framework for defining and building cloud infrastructures backed by AWS and powered by kubernetes. It couples best-of-breed technologies with engineering best-practices to equip organizations with the tooling that enables clusters to be spun up in record time without compromising security.

It's works natively with Mac OSX, Linux, and Windows 10 (WSL).

This project is part of our comprehensive "SweetOps" approach towards DevOps.

It's 100% Open Source and licensed under the APACHE2.

Introduction

These days, the typical software application is distributed as a docker image and run as a container. Why should infrastructure be any different? Since everything we write is "Infrastructure as Code", we believe that it should be treated the same way. This is the "Geodesic Way". Use containers+envs instead of unconventional wrappers, complicated folder structures and symlink hacks. Geodesic is the container for all your infrastructure automation needs that enables you to truly achieve SweetOps.

Geodesic is composed of two parts:

It is an interactive command-line shell. The shell includes the ultimate mashup of cloud orchestration tools. Those tools are then integrated to work in concert with each other using a consistent framework. Installation of the shell is as easy as running a docker container.
It is a distribution of essential services and reference architectures. The distribution includes a collection of 100+ Free Terraform Modules and their invocations, dozens of preconfigured Helmfiles, Helm charts for CI/CD, VPN, SSH Bastion, Automatic DNS, Automatic TLS, Automatic Monitoring, Account Management, Log Collection, Load Balancing/Routing, Image Serving, and much more. What makes these charts even more valuable is that they were designed from the ground up to work well with each other and integrate with external services for authentication (SSO/OAuth2, MFA).

An organization may chose to leverage all of these components, or just the parts that make their life easier. We recommend starting by using geodesic as a Docker base image (e.g. FROM cloudposse/geodesic:... pinned to a release and base OS) in your projects.

Note: Starting with Geodesic version 0.138.0, we distribute 2 versions of Geodesic Docker images, one based on Alpine and one based on Debian, tagged VERSION-BASE_OS, e.g. 0.138.0-alpine. Prior to this, all Docker images were based on Alpine only and simply tagged VERSION. At present, the Alpine version is the most thoroughly tested and best supported version, and the special Docker tag latest will continue to point to the latest Alpine version while this remains the case. However, we encourage people to use the Debian version and report any issues by opening a GitHub issue, so that we may eventually make it the preferred version, after which point the latest tag will point to latest Debian image. We will maintain the latest-alpine and latest-debian Docker tags for those who want to commit to using one base OS or the other but still want automatic updates.

Note: Geodesic is a large collection of tools. As such, support for the Apple M1 chip is not under Cloud Posse's control, rather it depends on each tool author updating each tool for the M1 chip. All of the compiled tools that Cloud Posse has authored and are included in Geodesic are compiled for M1 (darwin_arm64), and of course all of the scripts work on M1 if the interpreters (e.g. bash, python) are compiled for M1. Unfortunatetly, this is only a small portion of the overall toolkit that is assembled in Geodesic. Therefore we do not advise using Geodesic on the M1 at this time and do not anticipate M1 will be well supported before 2022. Historically, widespread support for a new chip takes several years to establish; we hope we will not have to wait that long.

Usage

Customizing your Docker image

In general we recommend creating a customized version of Geodesic by creating your own Dockerfile starting with

ARG VERSION=0.138.0
ARG OS=debian
FROM cloudposse/geodesic:$VERSION-$OS

# Add configuration options such as setting a custom BANNER,
# setting the initial AWS_PROFILE and AWS_DEFAULT_REGION, etc. here

ENV BANNER="my-custom-geodesic"

You can see some example configuration options to include in Dockerfile.options.

You can also add extra commands by installing "packages". Both Alpine and Debian have a large selection of packages to choose from. Cloud Posse also provides a large set of packages for installing common DevOps commands and utilities via cloudposse/packages. The package repositories are pre-installed in Geodesic, all you need to do is add the packages you want via RUN commands in your Dockerfile.

Installing packages in Alpine

Under Alpine, you install a package by specifying a package name and a repository label (if not the default repository). (You can also specify a version, see the Alpine documentation for details). In addition to the default package repository, Geodesic installs 3 others:

Repository Label	Repository Name
@testing	edge/testing
@community	edge/community
@cloudposse	cloudposse/packages

As always, because of Docker layer caching, you should start your command line by updating the repo indexes, and then add your packages. Alpine uses apk. So, to install Teleport support from the Cloud Posse package repository, pinned to version 4.2.x (which is the last to support Alpine), we can add this to our Dockerfile:

RUN apk update && apk add -u teleport@cloudposse=~4.2

Installing packages in Debian

Debian uses apt for package management and we generally recommend using the apt-get command to install packages. In addition to the default repositories, Geodesic pre-installs the Cloud Posse package repository and the Google Cloud SDK package repository. Unlike with apk, you do not need to specify a package repository when installing a package because all repositories will be searched for it. Also unlike apk, apt-get does not let you specify a version range on the command line, only an exact version. So to install the Google Cloud SDK at a specific version, you need to include a trailing -0 to indicate the package version. For example, to install version Google Cloud SDK 300.0.0:

RUN apt-get update && apt-get install -y google-cloud-sdk=300.0.0-0

Note the -y flag to apt-get install. That is required for scripted installation, otherwise the command will ask for confirmation from the keyboard before installing a package.

Customizing your shell at launch time

After you have build your Docker image, or if you are using a shared Docker image, you can add further customization at launch time. When Geodesic stars up, it looks for customization scripts and configuration so you can do things like add command aliases or override preconfigured options. Detailed information about launch-time configuration is in the customization document, available from within the shell via man customization.
