This should now be fully documented and ready to merge, and replaces #44 (by virtue of integrating the most recent cloud-init server). However, we may also want to look at the details of #44, particularly |
Note that we do not perform SSH host key checking. Host keys are treated as secrets, and will be applied via cloud-init *after* all TPM operations have completed (since this needs the key that we store into the TPM).
When a node requests its bootscript, BSS can now initiate a POST request to and endpoint of the user's choice — in this case, to the TPM manager daemon. This notification includes the booting node's IP address, which is passed to Ansible as inventory to be configured with a TPM key.
The tpm-manager compose file, in particular, includes an override clause which enables the cloud-init server's "secure route" (i.e. JWT-authenticated config data).
This is, usually, required so that Ansible in the container can SSH to nodes.
