cluster.name
editcluster.name
editA node can only join a cluster when it shares its cluster.name
with all the
other nodes in the cluster. The default name is elasticsearch
, but you should
change it to an appropriate name which describes the purpose of the cluster.
cluster.name: logging-prod
Make sure that you don’t reuse the same cluster names in different environments, otherwise you might end up with nodes joining the wrong cluster.
