Fly.io Install & Auth

Overview

Install flyctl CLI and configure authentication for Fly.io edge compute platform. Two auth methods: interactive login (opens browser) and API tokens (CI/CD and Machines API). The Machines API base URL is https://api.machines.dev.

Prerequisites

• Fly.io account at fly.io
• macOS, Linux, or WSL2

Instructions

Step 1: Install flyctl

# macOS / Linux
curl -L https://fly.io/install.sh | sh

# Or via Homebrew
brew install flyctl

# Verify
fly version

Step 2: Authenticate

# Interactive login (opens browser)
fly auth login

# Or with token (CI/CD)
fly auth token  # Get current token
export FLY_API_TOKEN="fo1_your_token_here"

# Verify auth
fly auth whoami

Step 3: Create API Token for Machines API

# Create deploy token (scoped to an app)
fly tokens create deploy -a my-app

# Create org-level token
fly tokens create org

# Use with Machines API
curl -s -H "Authorization: Bearer $FLY_API_TOKEN" \
  https://api.machines.dev/v1/apps | jq '.[].name'

Step 4: Verify Machines API Access

const FLY_API = 'https://api.machines.dev';

async function verifyFlyAccess() {
  const res = await fetch(`${FLY_API}/v1/apps`, {
    headers: { :  },
  });
   apps =  res.();
  .();
  apps.( .());
}
