cloud-init

README

This is a fork of CoreOS's cloud-init repo. Documentation might not be exactly up to date with the current code's functionality.

Configuration with cloud-config

A subset of the official cloud-config spec is implemented by cloud-init. Additionally, kip/itzo specific options are implemented to support a lightweight boot configuration for cloud instances

All supported cloud-config parameters are documented here.

The following is an example cloud-config document:

#cloud-config

users:
  - name: core
    passwd: $1$allJZawX$00S5T756I5PGdQga5qhqv1

write_files:
  - path: /etc/resolv.conf
    content: |
        nameserver 192.0.2.2
        nameserver 192.0.2.3

Executing a Script

cloud-init supports a custom section for a user supplied script:

runcmd:
  - echo 'Hello, world!'

user-data Field Substitution

cloud-init will replace the following set of tokens in your user-data with system-generated values.

Token	Description
$public_ipv4	Public IPv4 address of machine
$private_ipv4	Private IPv4 address of machine

These values are determined based on the given provider on which your machine is running.
