You will need an AppleID account.

I tried unsuccessfully to create one of these using the App Store app on the mac1.metal instance. If you need a new AppleID for your project, go to https://appleid.apple.com/account to create one.

Set up VSCode to develop on EC2 instances

Introduction

Using an EC2 instance to do development allows numerous scenarios, like doing vanilla Linux/Unix development on a Windows host machine. Wouldn’t it be great to use amazing tools like Visual Studio Code to develop on an EC2 instance too, right from the device at your desk?

Visual Studio Code has a very nice feature to allow this, using the Remote-SSH extension. It can SSH into the EC2 instance, install the Visual Studio Code agent, and give you the shell prompt on the EC2 instance. Further, the development folder on the EC2 instance can be opened in Visual Studio, so that the whole application context appears to be on the EC2 instance.

Let’s set this up.
