Опис

You should rotate swarm node certificates in line with your organizational security policy. Docker Swarm uses TLS for clustering operations between its nodes. Certificate rotation ensures that in an event such as a compromised node or key, it is difficult to impersonate a node. Reported as a manual review item: the audit needs a site-specific judgement.
