Securing APIs with Spire and OpenZiti

This repository leverages two fantastic open source projects (three including golang):

If you find the amazing levels of security and functionality these projects provide, go give them a hard-earned GitHub star!

Both projects are focused on securing APIs and both go about it in slightly different ways. This repo will show you how to take an insecure API, exposed via plain HTTP and secure it with both SPIRE and OpenZiti. There are four main paths to take to run the project. You can:

Running One or More Examples

Regardless of which of the secure examples you run, to run them you'll need to make sure you have SPIRE setup. By far, the lowest friction way of doing this is to just run the provided helper script in your bash shell. This script will do a lot for you.

You are highly encouraged to read the script. It shows you exactly what commands need to be run and in what order for them to function. The script serves as a way for you to read and explore each command, understand what it does what it does, and why.

Dependencies, Prerequisites, Assumptions

The script has the following dependencies:

  • The files downloaded are all linux-based. If you use MacOS, update the DL_ARCH variable in the script
  • The files will all be saved to TMP_DIR which by default is set to /tmp/dovholuknf/qcon2023.
  • go will be needed to build the samples
  • docker (and the newer docker compose)
  • killall is used to stop any existing servers (in lieu of something more robust like pid tracking)
  • it will use sudo to delete the folder at /tmp/dovholuknf/qcon2023 when it runs
  • curl, tar, sed are all needed along with other standard commands: mv, export, echo, sleep, cat, etc.
  • ip will be used to find eth0's IP. if you don't have an eth0, find eth0 in the script and update it
  • you will need to add: 127.0.0.1 ziti-edge-controller ziti-edge-router to your /etc/hosts or you'll need to know how to get ziti-edge-controller and ziti-edge-router as hostnames routable into the docker environment that will spin up
  • it'll use sudo to run your spire agent as root. this is done so that when workloads attest, the agent can figure out who is attempting to attest. Obviously, this is not 'a good idea' but it's an easy, expedient way of getting the agent the proper permissions

Cleaning Up

The script has within it all the cleanup steps you need. This will come down to:

  • stopping docker compose:

    TMP_DIR=/tmp/dovholuknf/qcon2023
    docker compose -f $TMP_DIR/docker-compose.yml --env-file=$TMP_DIR/.env -p qcon2023 down -v
    
  • stopping the SPIRE server, agent and oidc-discovery-provider:

    sudo killall spire-server
    sudo killall spire-agent
    sudo killall oidc-discovery-provider
    
  • Removing any related identities from your locally running tunneler (if any)
