I have a six node cluster trying to upgrade to 7 from 6.8. Can't elect a master. Each node is a docker container on seperate machines. The config files on master are set:
cluster.name: "docker-cluster" network.host: 0.0.0.0 node.name: "bex" network.publish_host: 10.230.0.1 node.master: true node.data: true # minimum_master_nodes need to be explicitly set when bound on a public IP # set to 1 to allow single node clusters # Details: https://github.com/elastic/elasticsearch/pull/17288 # discovery.zen.minimum_master_nodes: 2 path.repo: ["/backups", "/nfsbackup"] discovery.seed_hosts: - 10.230.0.4 - 10.230.0.3 ##discovery.zen.ping.unicast.hosts: logger.org.elasticsearch.cluster.coordination: TRACE cluster.initial_master_nodes: - 10.230.0.1 - 10.230.0.3 - 10.230.0.4
Nodes are called bex, el3, el4.

Any help enormously appreciated!
