The certmanager and sshsigner approles are bound to the six legacy VM
puppet-master IPs, so the HPA-autoscaled k8s compilers cannot log in and
every catalog compile that issues a cert or signs a host key fails.
- Add k8s auth roles puppet_certmanager and puppet_sshsigner on
k8s/au/syd1, bound to the default service account in namespace puppet
- Attach the existing pki_int/pki certmanager and sshca signing policies
to them, matching the approle token TTLs
- Leave the approle roles and their CIDR bindings untouched
