Before you begin:

  1. Create your VM with a template that is compatible with cloud-init version 0.7.9 or above, or cloudbase-init, or a similar system

  2. In private cloud, the platform will create an ISO disk for Configuration drive

To add a VM bootstrap configuration or script in private or public cloud:

  1. Create or edit a VM, and go to Bootstrap script

  2. Paste your configuration or script in the Bootstrap script text box

  3. Continue to configure the VM or click Save to finish

Edit a VM and add a bootstrap script

Notes about bootstrap in private cloud

  1. If the user does not enter the FQDN on the General tab when editing the VM, the platform will try to set the FQDN using the name or ID attribute of the VM, and the domain of the VM's networks, or the localhost domain

  2. If your datacenter does not use DHCP, the VM can also get its network configuration from cloud-init, so you do not need to configure the network or allow access to the VM

  3. Abiquo uses the ConfigDrive DataSource for cloud-init. Reference: https://cloudinit.readthedocs.io/en/latest/topics/datasources/configdrive.html

Notes about startup scripts in AWS

  1. In Amazon Web Services you must always select a guest setup option

  2. In AWS, for Windows, depending on the template and its guest setup option, the script format is:

    1. cloudbase_init: cloud-init or shellscript

    2. ec2launch and ec2config: you must have the following format

      1. batch script: put a <script> tag at the start, and a </script> tag at the end of the script

      2. powershell script: put a <powershell>tag at the start, and a </powershell> tag at the end of the script

    3. ec2launch v2: use YAML. See https://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/ec2-windows-user-data.html#user-data-yaml-scripts.
      If your script format is invalid, AWS will try ec2launch and ec2config format. See: https://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/ec2-windows-user-data.html

Notes about startup scripts in OCI

  1. The Windows templates provided by Oracle Cloud Infrastructure include cloudbase-init.
