Cloud-init does not work on RHEL BYOI to BM.

phenomenon

• https://urldefense.com/v3/__https://github.com/oracle-quickstart/oci-byo-image__;!!ACWV5N9M2RV99hQ!dHBfMouBp2fXGhfvJ7Bp5Hoz3DHUeSYFRyO-8L7_7a65T1Wz Cloud-init does not work properly with the RHEL bare metal image created by the procedure of this URL (cloud-init does not bring information such as public key from the metadata server)
• In the virtual server image created by the same procedure, cloud-init is operating normally.

How to create an image

• Create an image of RHEL7.9 with Virtual Box using Packer from the above Github
• Send the finished image to OCI and convert it to a custom image
• Deploy bare metal server from custom image with BM.Optimized3.36
• Upgrade the above server to RHEL 8.4 with RHEL in-place upgrade

• Install cloud-init with yum, copy 99_cloud.cfg installed on Oracle Linux to the specified location, and restart.

log

• Attach the log with the problem and the log (/var/log/cloud-init.log) when deploying with Oracle Linux 8. The problem log did not record access to the metadata server. Also, it seemed that 99_oci.cfg itself was not executed, such as an error occurred when setting the default GW and no other swap file was created.

Workaround

• The operation itself can be done by logging in from the serial console using an account created separately from opc. However, since the operation method differs between bare metal and virtual server, I would be grateful if there was a solution.

Please let me know if there is a solution.

Is such a write good here?

@MktMatsuyama I believe I am able to get RHEL with cloud-init to work on Bare Metal with RHEL 7.9 but not 8.x. Is Bare Metal a requirement?

[MktMatsuyama]

Thank you. Bare metal + RHEL 8.4 is required. Currently, we are working on bare metal + RHEL 8.4 by setting the ssh public key etc. using the serial console.
