I have a tentacle 20.2.1 cluster managed by cephadm, where I have configured a certificate for the rgw using something like: service_type: ingress service_id: rgw.default service_name: ingress.rgw.default placement: count: 3 label: rgw spec: backend_service: rgw.default first_virtual_router_id: 50 frontend_port: 443 monitor_port: 8080 virtual_ip: 10.0.40.3/24 networks: - 10.0.40.0/24 ssl_cert: | -----BEGIN CERTIFICATE----- *snip* -----END CERTIFICATE----- -----BEGIN CERTIFICATE----- *snip* -----END CERTIFICATE----- -----BEGIN RSA PRIVATE KEY----- *snip* -----END RSA PRIVATE KEY----- This initially worked perfectly, but I have just rotated the certificate by generating the yaml with a fresh private key and associated certificate then installing it with: ceph orch apply -i new.yaml Clients accessing the rgw ingress get the correct certificate and work perfectly, both before and after the key rotation. I have a script that does this for me daily, and until the certificate was rotated, everything was fine, but then I got this error: # ceph orch certmgr cert check Certificate 'ingress_ssl_cert (ingress.rgw.default)' (user-made) is not valid (error: Invalid cert/key pair: [('x509 certificate routines', '', 'key values mismatch')]) After messing with the certificate a bunch I now get a completely different, but also worrying error: # ceph orch certmgr cert check - Certificate 'ingress_ssl_cert (ingress.rgw.default)' (user-made) is not valid (error: Invalid private key: [('DECODER routines', '', 'unsupported')]) The documentation offers no help: https://docs.ceph.com/en/tentacle/cephadm/certmgr/ The error seems to come from this code: https://github.com/ceph/ceph/blob/main/src/python-common/ceph/cryptotools/in... So the error is an amputated exception from somewhere in openssl but the actual exception is eaten by the code, so there is no way for me to debug the situation: https://github.com/ceph/ceph/blob/main/src/python-common/ceph/cryptotools/in... I have tried installing the old certificate and key, that only leads the the Invalid private key: [('DECODER routines', '', 'unsupported')] error. I have tried re-formatting the pkcs#1 RSA key as PKCS#8, but that does nothing. I have even tried copying the key and cert pem files into the mgr container and verified them using the openssl installed in the container. The certificates are generated by cert-manager, running in k8s and a cronjob that periodically pushes the new key/cert to the ceph cluster via ssh. Has anyone seen these types of errors before? -- Flemming Frandsen - YAPH - http://osaa.dk - http://dren.dk/
