The LP bug referenced below describes a number of issues when
cinder tries to use etcd for its distributed lock manager with
internal TLS enabled. This patch resolves issues related to
generating and distributing etcd's cert and key files.
- The etcd cert must contain a subject alternative name (SAN) for the
etcd node's internal API IP address. This is necessary because etcd
wants to use IP addresses (versus host names), and this requires the
IP address be listed in the TLS certificate.
- The cert and key files are generated on the host, and must be
available to multiple services running in their respective containers.
The cert and key files need to be bind mounted, and an ACL is
required so the etcd and cinder services have permission to read the
files.
EnableEtcdInternalTLS, a workaround introduced in [1], still defaults
to False. The default value can be switched to True after tripleo
switches from using novajoin to the ansible tripleo-ipa role for
registering nodes with the IdM service.
