Instances

An instance is a Genesis Cloud virtual machine. By sending requests to the instances endpoint, you can list, create and delete instances.

Instance Schema

id String - A unique identifier for each instance. This is automatically generated.
name String - The human-readable name set for the instance.
hostname String - The instance host name.
dns_name String - The instance DNS name.
type String - The instance type (eg. vcpu-8_memory-32g_nvidia-rtx-3080-1).
region String - The region identifier this instance exists in (eg. NORD-NO-KRS-1).
placement_option String - The placement option identifier (eg. AUTO).
image Object - The instance base image object.
floating_ip Object - The floating IP attached to the instance.
ssh_keys Array - The instance's ssh keys.
security_groups Array - The instance's security groups.
volumes Array - The instance's volumes.
is_protected String - The instance termination protection flag.
status String - The instance status. Possible values are creating, pending_payment, active, stopping, stopped, starting, resetting, error and deleting.
private_ip String - The instance private ip. It may take some time to be assigned after the instance is created.
public_ip String - The instance public ip. It may take some time to be assigned after the instance is created.
disk_size Integer - The storage size of the instance's boot volume given in GiB (Min: 80GiB).
created_at String - A time value given in ISO8601 combined date and time format that represents when the instance was created.
updated_at String - A time value given in ISO8601 combined date and time format that represents when the instance was updated.

Create an Instance

Please Note: Creating an instance results in costs according to Genesis Cloud's pricing. You can see all your billed resources in the billing dashboard.

To create a new instance, send a request to:

POST /compute/v1/instances (HTTP 201 - Created)

The attribute values that must be set to successfully create an instance are:

Body parameters

name String _^Required - The human-readable name set for the instance.
hostname String _^Required - The hostname of your instance.
type String _^Required - The instance type identifier, see Instance Types.
region String _^Required - The region identifier in which this instance should be created in, see Regions.
placement_option String _^Optional - The placement option identifier in which instances are physically located relative to each other within a zone. Defaults to AUTO.
image String _^Required - The image id, image slug or snapshot id. The image version can also specified together with the image slug in this format <image-slug>:<version>, see image schema.
floating_ip String _^Optional - The id of the floating IP to attach to the instance.
ssh_keys Array _^Required - An array of ssh key ids. This should not be provided if password authentication method is desired.
volumes Array _^Optional - An array of volume ids. Please Note: These should be ids for valid volumes with a status of available, see volume schema.
password String _^Optional - The password to access the instance. Your password must have a minimum length of 16 characters. Please Note: Only one of ssh_keys or password can be provided. Password is less secure - we recommend you use an SSH key-pair instead.
security_groups Array _^Optional - An array of security group ids. Please Note: Passing the empty array will result in an instance without any security groups.
is_protected Boolean _^Optional - Specifies if the instance is termination protected. When set to true, it's not possible to destroy the instance until it's switched to false. Set to true automatically for long-term billed instances. Defaults to false.
disk_size Integer _^Optional - The storage size of the instance's boot volume given in GiB (Min: 80GiB). If the field is not set, the default is 80GiB.
metadata Object _^Optional - Option to provide metadata.
- A startup_script is a plain text bash script or 'cloud-config' file that will be executed after the first instance boot. It is limited to 64 KiB in size. You can use it to configure your instance, e.g. installing the NVIDIA GPU driver. Learn more about startup scripts and installing the GPU driver.
- Provide custom user_data in a variety of formats. You can use it for example to provide a cloud-config file via the "text/cloud-config" type. The filename is optional, but it can be useful when debugging inside the instance.
  User data Schema
  - type String
  - filename String (optional)
  - content String
