flyctl is a command-line interface for fly.io.

Note: Most installations of flyctl also alias flyctl to fly as a command name, and this will become the default name in the future. During the transition, note that where you see flyctl as a command, it can be replaced with fly.

brew install flyctl

To upgrade to the latest version:

1. Sign into your Fly account:

   fly auth login

2. List your apps:

   fly apps list

3. View app status:

   fly status -a {app-name}

flyctl will attempt to use the app name from a fly.toml file in the current directory. For example, if the current directory contains this file:

$ cat fly.toml
app: banana

flyctl will operate against the banana app unless overridden by the -a flag or another app name setting in the command line.

flyctl is automatically released at 3 PM Eastern Standard Time, Monday - Thursday. If needed, you can bump a release by running ./scripts/bump_version.sh.

There is a simple PowerShell script, winbuild.ps1, which will run the code generation for the help files, format them, and run a full build, leaving a new binary in the bin directory.
