Getting Started

Getting Started#

Fly.io is a deployment platform that enables application deployment across a global network of edge-servers. It utilizes container-based deployment strategies and provides automated load balancing, SSL management, and horizontal scaling capabilities.

Prerequisites#

Required components: - Terminal access - Git - Fly.io account - Application codebase - Docker installed locally (recommended)

CLI Installation#

The Fly CLI is the primary interface for managing deployments and resources.

MacOS#

brew install flyctl

Linux#

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

Windows#

powershell -Command "iwr https://fly.io/install.ps1 -useb | iex"

Authentication#

Initialize CLI authentication:

fly auth login

This command initiates an OAuth flow in your default browser for account authentication.

Application Configuration#

Python/Flask Configuration#

Required files for Flask deployments:

FROM python:3.9-slim

WORKDIR /app

COPY requirements.txt .
RUN pip install -r requirements.txt

COPY . .

ENV FLASK_APP=app.py
ENV FLASK_ENV=production

CMD ["gunicorn", "--bind", "0.0.0.0:8080", "app:app"]

flask
gunicorn

Node.js/NestJS Configuration#

Required files for NestJS deployments:

FROM node:16-slim

WORKDIR /app

COPY package*.json ./
RUN npm install

COPY . .
RUN npm run build

CMD ["npm", "run", "start:prod"]

Deployment Process#

Initialize deployment configuration:

fly launch

This command executes the following operations:

  1. Application name assignment

  2. Framework/runtime detection

  3. fly.toml configuration generation

  4. Initial deployment setup

Deployment Configuration#

Standard fly.toml configuration file:

app = "application-name"

[build]
    builder = "paketobuildpacks/builder:base"

[env]
    PORT = "8080"

[http_service]
    internal_port = 8080
    force_https = true

[[services.ports]]
    handlers = ["http"]
    port = 80

[[services.ports]]
    handlers = ["tls", "http"]
    port = 443

Core CLI Commands#

Application Management:

# Deploy application updates
fly deploy

# Monitor application status
fly status

# Access application logs
fly logs

# Launch application in browser
fly open

# Configure application scaling
fly scale count 2  # Horizontal scaling to 2 instances

Best Practices#

  1. Deployment Strategy - Initialize with minimal configuration - Implement incremental feature additions - Validate each deployment phase

  2. Monitoring - Implement comprehensive logging - Monitor resource utilization - Track performance metrics

  3. Security - Utilize fly secrets for sensitive data - Implement proper access controls - Regular security audits

Troubleshooting Protocol#

When encountering deployment issues:

  1. Execute log analysis:

fly logs

  1. Validate configuration integrity in fly.toml

  2. Verify container functionality locally

  3. Consult error-specific documentation

Advanced Configuration#

Post-deployment considerations: - Domain configuration and DNS management - SSL/TLS certificate implementation - Database integration and management - CI/CD pipeline integration - Scaling and performance optimization

Resource Management#

Key considerations for resource allocation: - CPU and memory allocation - Network bandwidth utilization - Storage requirements - Cost optimization strategies
