- fix: Set ssh_public_key to null (not "") in heat/environment.yaml
- fix: Comment ssh_public_key in ansible/vars.yaml
- fix: Comment ssh_public_key in tf/vars.tfvars
Without this change, if the user neglects to set the ssh_public_key stack parameter, they get an error message that is rather unhelpful to a new user: ERROR: The public_key property is required by the nova API version currently used. By setting it to null (instead of the empty string) in heat/environment.yaml, they instead get: ERROR: The Parameter (ssh_public_key) was not provided. ... which is a much more self-explanatory message.
When setting ssh_public_key to null or the empty string, the Ansible playbook proceeds and completes successfully, but creates an invalid SSH keypair and thus an invalid authorized_keys file in the Pad Ramp host. Thus, comment out the variable in ansible/vars.yaml (leaving it undefined), which causes the playbook to fail outright because of a reference to an undefined variable.
When setting ssh_public_key to null or the empty string, "tofu apply" proceeds and completes successfully, but creates an invalid SSH keypair and thus an invalid authorized_keys file in the Pad Ramp host. Thus, comment out the variable in tf/vars.tfvars (leaving it undefined), which causes OpenTofu to prompt for the missing variable (unless a TF_VAR_ssh_public_key environment variable is set).
