Cloud-Init Configuration Documentation

This cloud-init configuration is used to initialize a virtual machine (VM) on Terraform. It sets up a user, updates and upgrades the system packages, installs necessary packages, and runs several commands.

User Setup

The configuration creates a user named ansible with the following properties:

  • The user is added to the users and admin groups.
  • The user is granted sudo privileges without the need for a password.
  • The user's default shell is set to /bin/bash.
  • An SSH public key is added to the user's authorized keys.

  - name: ansible
    groups: users, admin
