Adding user data to your VSI on VPC landing zone deployable architecture

{: #user-data}

You can specify optional user data that automatically performs common configuration tasks or runs scripts on your VSI on VPC landing zone deployable architecture. For more information, see docs. {: shortdesc}

To set user data for the VSIs, you need to pass a map to the optional user_data input variable.

Example

{: #user-data-example}

When using the user_data variable in your configuration, it's essential to provide the content in the correct format for it to be properly recongnized by the terraform.

The user_data variable should contain data formatted as follows:

{
  management = {
    user_data = <<-EOT
#cloud-config
# vim: syntax=yaml
write_files:
- content: |
    # This is management
  path: /etc/sysconfig/management
EOT
  }
  workload = {
    user_data = <<-EOT
#cloud-config
# vim: syntax=yaml
write_files:
- content: |
    # This is workload
  path: /etc/sysconfig/workload
EOT
  }
}

• Keys to the map should be the same as the vpc names.
• Value for the user_data parameter in the object should follow YAML formatting.
• Use <<-EOT and EOT to enclose your user_data content to ensure it's passed as multi-line string.
