Portable cloud initialization service
Project description
The main goal of this project is to provide guest cloud initialization for Windows and other operating systems.
The architecture of the project is highly flexible and allows extensions for additional clouds and plugins.
There’s no limitation in the type of supported Hypervisor. This service can be used on instances running on Hyper-V, KVM, Xen, ESXi, etc

Binaries
The following x64 and x86 builds are automatically generated by a Jenkins job at every commit:

Metadata services
A metadata service has the role of pulling the metadata configuration information.
Supported clouds and metadata services:
OpenStack (HTTP)
OpenStack (ConfigDrive)
Amazon EC2
CloudStack
OpenNebula
Ubuntu MAAS
Plugins
Plugins execute actions based on the metadata obtained by the service.
cloudbaseinit.plugins.common.sethostname.SetHostNamePlugin
Sets the instance’s hostname.
cloudbaseinit.plugins.windows.createuser.CreateUserPlugin
Creates a local cloud user (if it does not already exist) and adds it to a set of provided local groups.
The following configuration parameters control the behaviour of this plugin.
Option |
Description |
Default |
|---|---|---|
username |
Name of the cloud user |
Admin |
groups |
Comma separated list of groups |
Administrators |
cloudbaseinit.plugins.common.setuserpassword.SetUserPasswordPlugin
Sets the cloud user’s password. If a password has been provided in the metadata during boot (user_data) it will be used, otherwise a random password will be generated, encrypted with the user’s SSH public key and posted to the metadata provider (currently supported only by the OpenStack HTTP metadata provider).
Option |
Description |
Default |
|---|---|---|
inject_user_password |
Can be set to false to avoid the injection of the password provided in the metadata |
True |
cloudbaseinit.plugins.common.networkconfig.NetworkConfigPlugin
Configures static networking.
Option |
Description |
Default |
|---|---|---|
network_adapter |
Network adapter to configure |
None |
If network_adapter is not specified, the first available ethernet adapter will be chosen if it cannot be matched with the configuration provided in the metadata.
cloudbaseinit.plugins.common.sshpublickeys.SetUserSSHPublicKeysPlugin
Creates an “authorized_keys” file in the user’s home directory containing the SSH keys provided in the metadata. It is needed by the cloudbaseinit.plugins.common.setuserpassword.SetUserPasswordPlugin plugin.
cloudbaseinit.plugins.windows.extendvolumes.ExtendVolumesPlugin
Extends automatically a disk partition to it’s maximum size. This is useful when booting images with different flavors.
cloudbaseinit.plugins.windows.winrmlistener.ConfigWinRMListenerPlugin
Configures a WinRM HTTPS listener to allow remote management via WinRS or PowerShell.
cloudbaseinit.plugins.windows.winrmcertificateauth.ConfigWinRMCertificateAuthPlugin
Enables password-less authentication for remote management via WinRS or PowerShell. See: http://www.cloudbase.it/windows-without-passwords-in-openstack/
cloudbaseinit.plugins.common.localscripts.LocalScriptsPlugin
Executes any script (e.g. Powershell, CMD, etc) located in the following path.
Option |
Description |
Default |

This is particularly useful for cases in which a lower MTU value is required for networking (e.g. OpenStack GRE Neutron Open vSwitch configurations).
Option |
Description |
Default |
|---|---|---|
mtu_use_dhcp_config |
Set MTU from DHCP |
True |
cloudbaseinit.plugins.common.userdata.UserDataPlugin
Executes custom scripts provided with the user_data metadata as plain text or compressed with Gzip.
Supported formats:
Windows batch
The file is executed in a cmd.exe shell (can be changed with the COMSPEC environment variable). The user_data first line must be:
rem cmd
PowerShell
The user_data first line must be:
#ps1_sysnative
or for a x86 PowerShell execution:
#ps1_x86
Bash
A bash shell needs to be installed in the system and available in the PATH in order to use this feature. The user_data first line must start with:
#!
e.g.:
#!/bin/bash

write_files
Defines a set of files which will be created on the local filesystem. It can be a list of items or only one item, with the following attributes:
path

content
The content which will be written in the given file
permissions
Integer representing file permissions
encoding
The encoding of the data in content. Supported encodings are: b64, base64 for base64-encoded content, gz, gzip for gzip encoded content, gz+b64, gz+base64, gzip+b64, gzip+base64 for base64 encoded gzip content.
Examples:
# One item write_files: encoding: b64 content: NDI= path: C:\test permissions: '0o466' # Multiple items write_files: - encoding: b64 content: NDI= path: C:\b64 permissions: '0644' - encoding: base64 content: NDI= path: C:\b64_1 permissions: '0644' - encoding: gzip content: !!binary | H4sIAGUfoFQC/zMxAgCIsCQyAgAAAA== path: C:\gzip permissions: '0644'set_timezone

MIME multi-part userdata is supported. The content will ne handled based on the content type.
text/x-shellscript
Any script to be executed: PowerShell, CMD, Bash or Python.
text/part-handler
