Fly.io Deployment

Practical examples and patterns for typical Fly.io deployment workflows

---

Prerequisites

Install and authenticate `flyctl`

Install flyctl

macOS

If using homebrew,

brew install flyctl

Otherwise,

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

If you used curl to install flyctl, then you need to add the flyctl directory to your shell rc file. Check the output of the install script for the entries to copy and paste into the file. Now you can use the fly command from any directory.

Linux

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

Windows

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

Authenticate flyctl

fly auth login
