Octavia: Could not retrieve certificate when create HTTPS listener using application credentials


Hi Pawel,

First question is what version of Octavia are you using? Older
versions required you to set some ACL permissions on the secrets in
Barbican. You can check this by reviewing the load balancing cookbook
for the version of Octavia you are running [1]. There is a drop down
in the upper right corner of the document that allows you to select a
version of the document.

Second question, can you expand on what you mean by "application
credentials"? Is this by using a pre-created token instead of having
the username/password in your environment?

Third, can you check your octavia.conf settings[2]? Check the
following options are either the default (commented out) or set to the
same settings as the default.
[certificates]
cert_manager = barbican_cert_manager
barbican_auth = barbican_acl_auth (Note, this is only valid in the
newer versions of Octavia as noted above)

Fourth (last one), can you provide the associated log output from the
Octavia API process that is handling this request? Debug if you can.

Michael
