![]() The configuration leverages the Prox圜ommand capability built in to SSH, so once configured, you are able to connect to the server using the native SSH commands.Īrgo Tunnel will cost you some money - at the time of writing, $5/mo per domain, along with a usage fee of $0.10 per gigabyte of data transfer, with the first GB being free.įollow these instructions to setup Access and install and configure Argo Tunnel your development VM. For this example, you should be able to use the free allocation of Access, which gives you the options of choosing Google, GitHub, Facebook, or One-Time Pin as the identity provider.Īn instance of Cloudflare's Argo Tunnel runs on both the client and server to facilitate the secure SSH session, allowing us to block all inbound ports to the VM. In this case, we'll setup a subdomain that will resolve to the the remote VM. These instructions detail how to create an account and configure a domain.Ĭloudflare Access integrates with existing identity providers and allow you to control who can access resources associated with your domain. To get started, create a free Cloudflare account, set up a domain, and enable the Access and Argo Tunnel products in your account. Zero Trust SSH With CloudflareĬloudflare can be used to create a zero trust configuration for the SSH connection between your local machine and the VM in Azure. ![]() When following the guide you'll notice that Azure warns that leaving port 22 open isn't a great idea. Then follow Microsoft's getting started instructions, which walks you through creating a virtual machine in Azure and configuring the VS Code extension for connecting to it via SSH. The first step to getting started in to install the VS Code extension. ![]() The VS Code extension architecture looks like this: However, there were a few downsides inherent in the architecture, a large one being that you are working in a code editor running on the host instead of your local machine, inevitably leading to the feeling of lag while typing. His post inspired me to experiment with this type of setup using my Google Pixelbook, which I ended up using for half of 2019. This can also be helpful those who enjoy hacking on a Raspberry Pi, providing a nice way of using your main computer with VS Code to develop your scripts on the Raspberry Pi without the need for finding a separate display or using VNC.Įarlier this year I ran into a post by Fatih Arslan, the original author of vim-go, about his experiment using an iPad Pro for development by leveraging remote virtual machines and containers hosted on DigitalOcean. Using virtual machines for development also allows experimentation with new configurations or libraries without fear of breaking your local setup or introducing security vulnerabilities. This gave me the chance to try out Cloudflare Access and Argo Tunnel for zero-trust security with SSH. Microsoft's getting started instructions were clear and easy to follow, but a bit loose on security - notably leaving port 22 exposed publicly for SSH. Over the weekend I set up a VM in both Azure and DigitalOcean as a test for using the Remote - SSH extension. ![]() This allows the benefit of authoring code in a locally running instance of VS Code while moving the compute to a remote host providing the power and unique configuration settings for your project. Microsoft recently released an exciting set of capabilities that allows a locally running instance of VS Code to attach to a remote VM or container that serves as the development environment. ![]()
