azure: fails with ignition+password auth
cgwalters opened this issue · comments
I booted a FCOS VM in Azure with just an Ignition config and --authentication-type password
to disable Azure's requirement for SSH keys.
[root@walters-fcos ~]# systemctl status afterburn-sshkeys@core

Thanks for the report.
I think that means that the XML value for this property is not a full-blown URL.
It would be interesting to dump the content of the goalstate
response and see what it actually contains.
Still seeing this in e.g. openshift/installer#3613
@cgwalters to the best of my knowledge you shouldn't be seeing this in OpenShift, as by design it is not supposed to use cloud SSH keys (unless that design decision changed at some point).

Ah, right: https://gitlab.cee.redhat.com/coreos/redhat-coreos/merge_requests/972
I do suspect we are getting back an empty property value or some other kind of magic marker. If that's indeed the way for the platform to signal "SSH keys are disabled", we should probably gracefully warn and exit without error in that specific case.
I just checked on a password-auth instance, and indeed there is no Certificates
entry in the Configuration
stanza. This is how the XML section there looks like:
<Configuration>
<HostingEnvironmentConfig>http://168.63.129.16:80/...</HostingEnvironmentConfig>
<SharedConfig>http://168.63.129.16:80/...</SharedConfig>
<ExtensionsConfig>http://168.63.129.16:80/...</ExtensionsConfig>
<FullConfig>http://168.63.129.16:80/...</FullConfig>
