Cloud-init is the perfect tool to provision a new instance. You can provide provisionning instructions to cloud-init using the cloud-init key of the user_data facility. In order for the user_data to be effective, it has to be added prior to starting the instance since cloud-init gets activated early in the first phases of the boot process cloud-init Documentation. Cloud-init is the industry standard multi-distribution method for cross-platform cloud instance initialization. It is supported across all major public cloud providers, provisioning systems for private cloud infrastructure, and bare-metal installations. Cloud instances are initialized from a disk image and instance data User data and cloud-init. Let's take a look how cloud-init is implemented in AWS first. In AWS we can put our configurations in user data of an instance. We're allowed to use both shell script and cloud-init directives in user-data field.. We can pass user data to an instance as plain text, as a file (this is useful for launching instances using the command line tools), or as base64.

Introduction. The cloud-init program that is available on recent distributions (only Ubuntu 14.04 and CentOS 7 at the time of this writing) is able to consume and execute data from the user-data field of the DigitalOcean metadata service.This process behaves differently depending on the format of the information it finds. One of the most popular formats for scripts within user-data is the. Cloud-init allows you to customize a new server installation during its deployment using data supplied in YAML configuration files. This tutorial will briefly introduce one method of utilizing cloud-init when provisioning servers at ProfitBricks. A quick rundown of the procedure we will follow is: Create the customized meta-data and user-data. While cloud-init started life in Ubuntu, it is now available for most major Linux and FreeBSD operating systems. For cloud image providers, then cloud-init handles many of the differences between cloud vendors automatically — for example, the official Ubuntu cloud images are identical across all public and private clouds Additionally, the version of cloud-init needed to consume the user-data field is currently only available in Ubuntu 14.04 and CentOS 7, as well as application images based on these releases. Through the control panel interface, there is an optional check box to enable user data If cloud-init is used to provision a physical appliance or device and an attacker can present a datasource to the device with a different instance ID, then cloud-init's default behavior will detect this as an instance's first boot and reset the device using the attacker's configuration (this has been observed with the NoCloud datasource.
