Deployment

Fly.io

Deploy Repix to Fly.io for global edge deployment.

Fly.io runs containers globally. Repix's Dockerfile works with minimal configuration.

Prerequisites

Install the Fly CLI:

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

# Or with Homebrew
brew install flyctl

Log in:

fly auth login

Deploy Steps

1. Launch the App

From your repix repository:

cd repix
fly launch

During setup:

  • App name: repix or custom
  • Region: Pick primary region (e.g., iad for US East)
  • Postgres/Redis: No (press Enter to skip)
  • Deploy now: Yes

2. Configure fly.toml

The generated fly.toml should work. Ensure the port matches:

# fly.toml
app = "repix"

[build]

[env]
  NODE_ENV = "production"
  PORT = "3210"

[[services]]
  internal_port = 3210
  protocol = "tcp"

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

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

  [services.concurrency]
    type = "requests"
    hard_limit = 25
    soft_limit = 20

  [[services.http_checks]]
    interval = "30s"
    timeout = "5s"
    path = "/health"

3. Set Secrets (Optional)

fly secrets set SOURCE_PREFIX=https://
fly secrets set IMAGE_MAX_WIDTH=2048
fly secrets set IMAGE_MAX_HEIGHT=2048

4. Deploy

fly deploy

Your app is at:

https://repix.fly.dev

Custom Domain

fly certs add images.yourdomain.com

Add a CNAME record pointing to repix.fly.dev.

Scaling

# Scale to 2 instances
fly scale count 2

# Use a larger machine for image processing
fly scale vm shared-cpu-2x

Health Check

Fly uses the path = "/health" in http_checks. Repix's /health endpoint satisfies this.
