cloud-init is the de facto industry standard for the initial set up, or bootstrapping, of Linux based virtual machines across every major cloud computing provider. Originally created as ec2-init for Ubuntu Server and designed to work with AWS EC2[1], as of 2023 it supports dozens of cloud providers and operating systems.

Use outside of public clouds

[edit]

cloud-init also works outside of public clouds. It is well integrated with OpenStack, OpenNebula, and Apache CloudStack.

cloud-config

[edit]

In addition to supporting configuration scripts passed through EC2's "user-data", or its equivalents on other clouds, in 2010 cloud-init introduced[4] a declarative mechanism called cloud-config for configuring virtual machines. This allows users to specify e.g. SSH keys to install, Chef recipes to run, certificate authorities to add[39], etc., and supported operating systems will use that configuration to make the requested changes. This way the same configuration can be used across different operating systems.
