On the customer’s BIG-IP instances, the cloud-init script fails to render the cloud provider’s name correctly. And so, cloud_name=unknown is set.
Whenever the cloud provider is not set to AWS, the DataSourceEc2.py cloud-init script, which is supposed to set up minimal network config with an ephemeral interface including fetching DHCP lease info, fails to do what it is supposed to and as a result metadata service is unreachable
Deploy BIG-IP VE on AWS in autoscaling group (1-NIC deployments) using Terraform.
The Identify_aws function is responsible to set the cloud name as AWS. The existing function fails when the network is not up. The customer had faced a similar issue. I have modified the function to check for UUID and serial. As these are available during boot-up itself, we are not dependent on network status.
Cloud-init now renders the cloud provider name (AWS) successfully. It does not depend on the network status anymore. Thus, AWS metadata crawling goes through smoothly.
