mirrord

Test in your remote staging environment without deploying to it

A hands-on intro to mirrord.

What is this? mirrord lets you run one service from a live Kubernetes cluster on your own machine. It "steals" that service's traffic, environment variables, and network so your local process behaves exactly as if it were running in the cluster — no deploy, no Docker, no rebuilds.

What you'll do: claim a seat, take over the inventory-service behind our MetalMart storefront, and run it on your laptop. Change a line, refresh the live store, and watch your laptop serving real cluster traffic in seconds.

Why it matters: this is how you develop and debug against real cluster dependencies instantly, instead of waiting on a build-and-deploy pipeline. Pick a path below to start — and if your laptop is locked down, just follow along on the screen.

☸ Kubernetes — your staging cluster frontend pod · the store UI inventory -service pod · the backend /products 💻 your laptop the backend, running locally mirrord steals the backend's traffic → it's served from your laptop
FAST PATH

Use the companion

A helper that does the setup, then prints the commands for you to run.

  1. Install it (curl, so macOS won't block it): 
    curl -fsSL https://storage.googleapis.com/mirrord-workshop-dist/install.sh | bash
  2. Set up your seat + install mirrord: 
    WORKSHOP_BROKER=https://mirrord-workshop.com/api workshop start --install
  3. It writes ~/mirrord-workshop and prints the kubectl + mirrord exec commands — open a terminal and run them yourself.
  4. Edit the PREFIX line in your backend, save, refresh your store. ✨
MANUAL PATH — no binary

Do it by hand

  1. Install mirrord: 
    curl -fsSL https://raw.githubusercontent.com/metalbear-co/mirrord/main/scripts/install.sh | VERSION=3.210.0 bash
  2. Claim your seat:
  3. Pick your language:
  4. Download these into one folder:
  5. From that folder, run:
  6. Open your store (link appears after you claim), edit PREFIX in the file, save, refresh.

Can't install anything on a locked-down laptop? No worries — just watch the screen; we'll drive it live.
