Running Kibana in a Docker container

Kibana's Docker image can be obtained from the Docker image warehouse on the Elastic official website. This image is packaged with X-Pack.

X-Pack comes pre-installed in this image. After X-Pack is installed, Kibana will connect to the Elasticsearch cluster that also has X-Pack.

Get image

You can obtain the Kibana Docker image by sending a docker pull command to the Elastic Docker repository.

The command is as follows:

docker pull docker.elastic.co/kibana/kibana:6.0.0

Configuring Kibana in Docker

Docker images provide several ways to configure Kibana. The traditional method is to give a configuration file kibana.yml described in Configuring Kibana . You can also use environment variables to define setting items.

Binding configuration

One way to configure Kibana in Docker is through the binding configuration file kibana.yml. Use the docker-compose tool to bind as follows:

services:
  kibana:
    image: docker.elastic.co/kibana/kibana:6.0.0
    volumes:
      - ./kibana.yml:/usr/share/kibana/config/kibana.yml

Environment variable settings

In Docker, Kibana can be set through environment variables. The environment variables are as follows:

SERVER_SSL_KEY	server.ssl.key
XPACK_MONITORING_ELASTICSEARCH_URL	xpack.monitoring.elasticsearch.url
XPACK_MONITORING_ELASTICSEARCH_USERNAME	xpack.monitoring.elasticsearch.username
XPACK_MONITORING_ELASTICSEARCH_PASSWORD	xpack.monitoring.elasticsearch.password
XPACK_MONITORING_ENABLED	xpack.monitoring.enabled
XPACK_MONITORING_MAX_BUCKET_SIZE	xpack.monitoring.max_bucket_size
XPACK_MONITORING_MIN_INTERVAL_SECONDS	xpack.monitoring.min_interval_seconds
XPACK_MONITORING_NODE_RESOLVER	xpack.monitoring.node_resolver
XPACK_MONITORING_REPORT_STATS	xpack.monitoring.report_stats
XPACK_MONITORING_KIBANA_COLLECTION_ENABLED	xpack.monitoring.kibana.collection.enabled
XPACK_MONITORING_KIBANA_COLLECTION_INTERVAL	xpack.monitoring.kibana.collection.interval
XPACK_MONITORING_UI_CONTAINER_ELASTICSEARCH_ENABLED	xpack.monitoring.ui.container.elasticsearch.enabled
XPACK_SECURITY_ENABLED	xpack.security.enabled

XPACK_SECURITY_ENCRYPTIONKEY	xpack.security.encryptionKey
XPACK_SECURITY_SECURECOOKIES	xpack.security.secureCookies
XPACK_SECURITY_SESSIONTIMEOUT	xpack.security.sessionTimeout

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	http://elasticsearch:9200
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。
