docker中的ElasticSearch集群始终在3节点配置中关闭一个主节点

我在三个docker容器中运行elasticsearch集群，docker-compose.yml如下所示 .

当我运行其中任何两个时，可以设置群集哪个状态为绿色，但是当我启动第三个群集时，群集中的一个节点被强制关闭（docker容器退出）并且没有记录错误消息shutdown elasticsearch节点 .

节点1 docker-compose.yml：

version: '2'
services:
elasticsearch:
image: docker.elastic.co/elasticsearch/elasticsearch:5.4.1
container_name: elasticsearch1
environment:
  - cluster.name=MoquiElasticSearch
  - bootstrap.memory_lock=true
  - discovery.zen.minimum_master_nodes=2
  - xpack.security.enabled=false
  - transport.publish_host=192.168.2.101
  - http.publish_host=192.168.2.101
  - discovery.zen.ping.unicast.hosts=192.168.2.101:9301,192.168.2.101:9302
  - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
  - TZ=Asia/Shanghai
ulimits:
  memlock:
    soft: -1
    hard: -1
mem_limit: 1g
ports:
  - 9200:9200
  - 9300:9300
