Configure datasources

These examples show datasource configuration options for various datasources.

The options shown are as follows:

  • timeout: The timeout value for a request at metadata service

  • max_wait: The length of time to wait (in seconds) before giving up on the metadata service. The actual total wait could be up to: len(resolvable_metadata_urls)*timeout

  • metadata_url: List of URLs to check for metadata services. There are no default values for this field.

NoCloud

#cloud-config
datasource:
  NoCloud:
    seedfrom: None
    fs_label: cidata
    user-data: |
      # This is the user-data verbatim
    meta-data:
      instance-id: i-87018aed
      local-hostname: myhost.internal

  • seedfrom: The default value is None. If found, it should contain a URL with <url>/user-data and <url>/meta-data. For example: seedfrom: http://my.example.com/i-abcde/

  • fs_label: The label on filesystems to be searched for NoCloud source

  • user-data and meta-data (optional): Allows a datasource to be provided directly.

SmartOS

#cloud-config
datasource:
  SmartOS:
    # For KVM guests:
    # Smart OS datasource works over a serial console interacting with
    # a server on the other end. By default, the second serial console is the
    # device. SmartOS also uses a serial timeout of 60 seconds.
    serial_device: /dev/ttyS1
    serial_timeout: 60
    # For LX-Brand Zones guests:
    # Smart OS datasource works over a socket interacting with
    # the host on the other end. By default, the socket file is in
    # the native .zoncontrol directory.
    metadata_sockfile: /native/.zonecontrol/metadata.sock
    # a list of keys that will not be base64 decoded even if base64_all
    no_base64_decode: ['root_authorized_keys', 'motd_sys_info',
                       'iptables_disable']
    # a plaintext, comma delimited list of keys whose values are b64 encoded
    base64_keys: []
    # a boolean indicating that all keys not in 'no_base64_decode' are encoded
    base64_all: False
