availability_domain

Gets the availability_domain of this InstanceConfigurationLaunchInstanceDetails. The availability domain of the instance.

Example: Uocm:PHX-AD-1

Returns:The availability_domain of this InstanceConfigurationLaunchInstanceDetails.
Return type:str
compartment_id

Gets the compartment_id of this InstanceConfigurationLaunchInstanceDetails. The OCID of the compartment.

Returns:The compartment_id of this InstanceConfigurationLaunchInstanceDetails.
Return type:str
create_vnic_details

Gets the create_vnic_details of this InstanceConfigurationLaunchInstanceDetails. Details for the primary VNIC, which is automatically created and attached when the instance is launched.

Returns:The create_vnic_details of this InstanceConfigurationLaunchInstanceDetails.
Return type:InstanceConfigurationCreateVnicDetails
defined_tags

Gets the defined_tags of this InstanceConfigurationLaunchInstanceDetails. Defined tags for this resource. Each key is predefined and scoped to a namespace. For more information, see Resource Tags.

Example: {"Operations": {"CostCenter": "42"}}

Returns:The defined_tags of this InstanceConfigurationLaunchInstanceDetails.
Return type:dict(str, dict(str, object))
display_name

Gets the display_name of this InstanceConfigurationLaunchInstanceDetails. A user-friendly name. Does not have to be unique, and it's changeable. Avoid entering confidential information.

Example: My bare metal instance

Returns:The display_name of this InstanceConfigurationLaunchInstanceDetails.
Return type:str
extended_metadata

Gets the extended_metadata of this InstanceConfigurationLaunchInstanceDetails. Additional metadata key/value pairs that you provide. They serve the same purpose and functionality as fields in the 'metadata' object.

They are distinguished from 'metadata' fields in that these can be nested JSON objects (whereas 'metadata' fields are string/string maps only).

Returns:The extended_metadata of this InstanceConfigurationLaunchInstanceDetails.
Return type:dict(str, object)
fault_domain

Gets the fault_domain of this InstanceConfigurationLaunchInstanceDetails. A fault domain is a grouping of hardware and infrastructure within an availability domain. Each availability domain contains three fault domains. Fault domains let you distribute your instances so that they are not on the same physical hardware within a single availability domain. A hardware failure or Compute hardware maintenance that affects one fault domain does not affect instances in other fault domains.

If you do not specify the fault domain, the system selects one for you. To change the fault domain for an instance, terminate it and launch a new instance in the preferred fault domain.

To get a list of fault domains, use the list_fault_domains() operation in the Identity and Access Management Service API.

Example: FAULT-DOMAIN-1

Returns:The fault_domain of this InstanceConfigurationLaunchInstanceDetails.
Return type:str
freeform_tags

Gets the freeform_tags of this InstanceConfigurationLaunchInstanceDetails. Free-form tags for this resource. Each tag is a simple key-value pair with no predefined name, type, or namespace. For more information, see Resource Tags.

Example: {"Department": "Finance"}

Returns:The freeform_tags of this InstanceConfigurationLaunchInstanceDetails.
Return type:dict(str, str)
ipxe_script

Gets the ipxe_script of this InstanceConfigurationLaunchInstanceDetails. This is an advanced option.

When a bare metal or virtual machine instance boots, the iPXE firmware that runs on the instance is configured to run an iPXE script to continue the boot process.

If you want more control over the boot process, you can provide your own custom iPXE script that will run when the instance boots; however, you should be aware that the same iPXE script will run every time an instance boots; not only after the initial LaunchInstance call.

The default iPXE script connects to the instance's local boot volume over iSCSI and performs a network boot. If you use a custom iPXE script and want to network-boot from the instance's local boot volume over iSCSI the same way as the default iPXE script, you should use the following iSCSI IP address: 169.254.0.2, and boot volume IQN: iqn.2015-02.oracle.boot.

For more information about the Bring Your Own Image feature of Oracle Cloud Infrastructure, see Bring Your Own Image.

For more information about iPXE, see http://ipxe.org.

Returns:The ipxe_script of this InstanceConfigurationLaunchInstanceDetails.
Return type:str
metadata

Gets the metadata of this InstanceConfigurationLaunchInstanceDetails. Custom metadata key/value pairs that you provide, such as the SSH public key required to connect to the instance.

A metadata service runs on every launched instance. The service is an HTTP endpoint listening on 169.254.169.254. You can use the service to:

  • Provide information to Cloud-Init to be used for various system initialization tasks.
  • Get information about the instance, including the custom metadata that you provide when you launch the instance.

Providing Cloud-Init Metadata

You can use the following metadata key names to provide information to Cloud-Init:

"ssh_authorized_keys" - Provide one or more public SSH keys to be included in the ~/.ssh/authorized_keys file for the default user on the instance. Use a newline character to separate multiple keys. The SSH keys must be in the format necessary for the authorized_keys file, as shown in the example below.

"user_data" - Provide your own base64-encoded data to be used by Cloud-Init to run custom scripts or provide custom Cloud-Init configuration. For information about how to take advantage of user data, see the Cloud-Init Documentation.

Note: Cloud-Init does not pull this data from the http://169.254.169.254/opc/v1/instance/metadata/ path. When the instance launches and either of these keys are provided, the key values are formatted as OpenStack metadata and copied to the following locations, which are recognized by Cloud-Init:

http://169.254.169.254/openstack/latest/meta_data.json - This JSON blob contains, among other things, the SSH keys that you provided for

"ssh_authorized_keys".

http://169.254.169.254/openstack/latest/user_data - Contains the base64-decoded data that you provided for "user_data".

Return type:dict(str, str)
shape

Gets the shape of this InstanceConfigurationLaunchInstanceDetails. The shape of an instance. The shape determines the number of CPUs, amount of memory, and other resources allocated to the instance.

Return type:str
source_details

Gets the source_details of this InstanceConfigurationLaunchInstanceDetails. Details for creating an instance. Use this parameter to specify whether a boot volume or an image should be used to launch a new instance.
