error placement-conflict

What it means#

The clauses of the roles must not contradict each other: shards/replication need journal in the same role; replication k needs replicas to allow at least k nodes; one label cannot have two values in needs; two roles must not expose the same port (a node may have several roles) and no role may expose the port of the cluster protocol; tls(acme:) and tls(cert:, key:) are alternatives.

Example#

cluster demo {
  role api  { expose 443 }
  role edge { expose 443 }   // <- placement-conflict
}

placement-conflict

How to fix#

Give each role its own port, or merge the roles.
