I have a question, how can I configure the certificates for an elastic cluster in version 8.10.3, it will contain master roles, coordinators, data and machine learning.
Is it intended to have several roles on the nodes, would the same certificate be used on a node for all roles?
Certificates are not related to or dependent on the node roles... completely independent concepts.
If you are using 8.10.3 Auto Security configuration will be the default. perhaps start here
