Deploy an example Go app to Fly

Example Go app

Getting Started

1. Install the Fly CLI

If you're on a Mac, you can install flyctl with Homebrew

$ brew install superfly/tap/flyctl

For other systems, use the install script:

curl https://get.fly.io/flyctl.sh | sh

Checkout the docs for more ways to install flyctl

2. Log In

Create a Fly account if you haven't already signed up. Then login with:

$ flyctl auth login

3. Clone the app

$ git clone https://github.com/superfly/go-example.git

4. Change into the example app directory

$ cd go-example

Deploy

1. Create a new app

$ flyctl apps create

2. Deploy

$ flyctl deploy

3. Find app's IP address

Each Fly app gets a unique IP address. You can view the IP address with:

$ flyctl info

4. View your app

Now it's time to see your app in action. Load the IP address in a browser or use curl:

$ curl http://<APP-IP>

Add a Secret and View Deployment Status

1. Set the Secret

The example app says hello to whatever is in the NAME env variable, or "World" of not set. Let's change the name:

$ flyctl secrets set NAME=you

2. View Deployment Status

New VMs are stared each time your app changes. Once the new VMs are running the old ones are stopped. You can view the progress of a deployment and status about your app's VMs with the status command:

$ flyctl status

View Logs

Everything your app writes to STDOUT and STDERR is visible in your app's logs:

$ flyctl logs
