Learn about configurations >

• cluster_name | string

  The name of the cluster. This option can only be set once per deployment. Once the cluster has been initialised, further changes to this option will be ignored. This setting is crucial to the cluster formation: only sub-clusters with the same name can form a fleet. If this option is left unset, and init_hold is false, the cluster name will be autogenerated. If init_hold is true, the cluster name will be set by the peer-cluster relation data. If set, and init_hold is false, the configured value will be used. If init_hold is true and the sub-cluster names do not match once related, the application will be put into Blocked state, and the cluster formation will not begin.

• init_hold | boolean

  Whether a cluster should wait for a peer_cluster relation to be initialized and started.

• plugin_opensearch_knn | boolean

  Default: True

  Enable opensearch-knn

• roles | string

  Comma separated list of the roles assigned to the nodes of this cluster. This option may contain spaces before/after the role names, make sure you remove leading/trailing spaces when splitting this list. Leave this setting blank to allow auto-assignment of roles. Only the the built-in roles are checked against, namely: cluster_manager, data, data.hot, data.warm, data.cold, ingest, coordinating, voting_only, ml. Other dynamic roles are not validated.
