Visual Studio Code

Visual Studio Code is an interactive development environment (IDE) or simply, a code editor. You may hear Visual Studio Code referenced as VSCode or just code in the industry. VSCode is free to use for many types of development and supports various extensions for syntax checking and highlighting depending on the code language you are working with. For this lab, you will be working primarily with YAML file types. One of the interactive aspects of an IDE when working with Python is being able to select a runtime interpreter, e.g. Python 3.8.2 or Python 3.9.2. In this lab, we will take this a step further by using VSCode's remote connection functionality.

The VSCode application that is opened on your desktop computers has its documents and terminal connected back to an Developer VM in RTP, North Carolina. VSCode is providing the code editor frontend while the Developer VM is acting as the file hosting and runtime environment. In essence, you will be developing locally, but running remotely.

Step 1 - Introduction to Development Environment

Navigate to your VSCode application. Your VSCode screen should look very similar to the screenshot shown below.

A few things to note:

  1. The SSH connection to the remote Developer VM
  2. The terminal prompt is the remote Developer VM and NOT the local Windows desktop computer
  3. As you create files throughout the lab, the files will show in the Documents Explorer pane
  4. When you execute Ansible throughout the lab, that will be done from the Terminal command line
  5. If terminal does not show up, access it manually from 'View' Menu

VSCode application will have presaved remote SSH Sessions to Developer VM, if not follow these steps to make SSH Connection to Developer VM:

  1. Click on Remote explorer button, and press the '+' icon to add new remote session
  2. Enter ssh 'username'@'DeveloperVM IP' (Credentials drop down is having IP address and user details of Developer VM)
  3. Select the ssh configuration file
  4. Once the host is added, click on Connect
