配置 Docker 中的 Kibana
Docker 镜像提供了几种方法来配置 Kibana。传统的方法是给出一个 配置 Kibana 中描述的配置文件 kibana.yml ，也可以使用环境变量来定义设置项。
绑定配置
一种配置 Docker 中 Kibana 的方法是通过绑定配置文件 kibana.yml 。使用 docker-compose 工具，向下面这样绑定：
services:
kibana:
image: docker.elastic.co/kibana/kibana:6.0.0
volumes:
- ./kibana.yml:/usr/share/kibana/config/kibana.yml
环境变量设置
在 Docker 中，Kibana 可以通过环境变量的方法设置。环境变量如下：

这些变量可以像下面这样，用 docker-compose 设置：
services:
kibana:
image: docker.elastic.co/kibana/kibana:6.0.0
environment:
SERVER_NAME: kibana.example.org
ELASTICSEARCH_URL: http://elasticsearch.example.org
优先使用环境变量，然后是配置文件 kibana.yml 中的配置项。
Docker 默认值
使用 Docker 时，下面的配置项有不同的默认值 ：
server.host
"0"
elasticsearch.url
elasticsearch.username
elastic
elasticsearch.password
changeme
xpack.monitoring.ui.container.elasticsearch.enabled
true
这些配置项的默认值在 kibana.yml 中设置。可以通过 自定义 kibana.yml 或者 环境变量覆盖这些默认值。
