A system administrator is tasked with setting up several virtual machines to join an existing cloud infrastructure. They need to ensure that each virtual machine is configured automatically upon boot with a specific hostname pattern, user credentials, and custom network configuration without manual intervention. Which technology would be the MOST effective for achieving this goal during the initial boot process?
Cloud-init is a widely used tool for the early initialization of cloud instances. It supports various cloud platforms and allows for the automatic configuration of the environment based on user-provided initialization metadata, such as setting hostnames, usernames, and network configurations through user-data scripts or configuration files. This makes it excellent for quickly bootstrapping new virtual machines with the necessary custom settings. Other tools like Puppet and Ansible are also used for automation and configuration management, but they are typically used post-boot for ongoing management, rather than during the initial boot process.
