# 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](https://fly.io)
- macOS, Linux, or WSL2
## Instructions
### Step 1: Install flyctl
```bash
# macOS / Linux
curl -L https://fly.io/install.sh | sh
# Or via Homebrew
brew install flyctl
# Verify
fly version
```
### Step 2: Authenticate
```bash
# 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
```bash
# 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 $FLY_API_TOKEN" \
https://api.machines.dev/v1/apps | jq '.[].name'
```
### Step 4: Verify Machines API Access
```typescript
const FLY_API = 'https://api.machines.dev';
async function verifyFlyAccess() {
const res = await fetch(`${FLY_API}/v1/apps`, {
headers: { 'Authorization': `Bearer ${process.env.FLY_API_TOKEN}` },
});
const apps = await res.json();
console.log(`Connected. Found ${apps.length} apps.`);
apps.forEach((app: any) => console.log(` ${app.name} (${app.organization.slug})`));
}
```
## Token Types
| Token Type | Scope | Lifetime | Use Case |
|------------|-------|----------|----------|
| User token | All orgs/apps | Until revoked | Development, personal |
| Deploy token | Single app | Until revoked | CI/CD per app |
| Org token | All apps in org | Until revoked | Org-wide automation |
| Machines token | API access | Until revoked | Machines API calls |
## Error Handling
| Error | Cause | Solution |
|-------|-------|----------|
| `Error: not authenticated` | No token set | Run `fly auth login` or set `FLY_API_TOKEN` |
| `401 Unauthorized` | Invalid/expired token | Regenerate with `fly tokens create` |
| `Could not find app` | Wrong app name | Check with `fly apps list` |
| `flyctl not found` | CLI not installed | Run install script above |
