【问题描述】：
为了使每个容器都成为默认桥的一部分，我在每个服务中添加了network_mode: bridge。这些成为桥接器的一部分，但容器没有与主机名连接。下面是配置。
docker-compose.yml
version: '2'
services:
elasticsearch:
build:
context: elasticsearch/
args:
ELK_VERSION: $ELK_VERSION
volumes:
- ./elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml:ro
ports:

- "9300:9300"
environment:
ES_JAVA_OPTS: "-Xmx256m -Xms256m"
network_mode: bridge
hostname: elasticsearch
logstash:

无法访问弹性搜索的 Kibana 日志：
$ docker logs docker-elk_kibana_1
{"type":"log","@timestamp":"2018-09-20T05:27:05Z","tags":["warning","elasticsearch","admin"],"pid":1,"message":"Unable to revive connection: http://elasticsearch:9200/"}
{"type":"log","@timestamp":"2018-09-20T05:27:05Z","tags":["warning","elasticsearch","admin"],"pid":1,"message":"No living connections"}
但是，在我没有提供任何网络相关配置的情况下，以下配置一切正常。
