Configuring Kibana on Docker

Configuring Kibana on Docker

edit

The Docker image provides several methods for configuring Kibana. The conventional approach is to provide a kibana.yml file as described in Configuring Kibana, but it’s also possible to use environment variables to define settings.

Bind-mounted configuration

edit

One way to configure Kibana on Docker is to provide kibana.yml via bind-mounting. With docker-compose, the bind-mount can be specified like this:

services:
  kibana:
    image: docker.elastic.co/kibana/kibana:5.2.2
    volumes:
      - ./kibana.yml:/usr/share/kibana/config/kibana.yml

Environment variable configuration

edit

Under Docker, Kibana can be configured via environment variables. The following mappings are available:

Table 1. Docker Environment Variables

Environment Variable	Kibana Setting
`ELASTICSEARCH_CUSTOMHEADERS`	`elasticsearch.customHeaders`
`ELASTICSEARCH_PASSWORD`	`elasticsearch.password`

These variables can be set with docker-compose like this:

services:
  kibana:
    image: docker.elastic.co/kibana/kibana:5.2.2
    environment:
      SERVER_NAME: kibana.example.org
      ELASTICSEARCH_URL: http://elasticsearch.example.org

Environment variables take precedence over settings configured in kibana.yml.

Docker defaults

edit

The following settings have different default values when using the Docker image:

`server.host`	`"0"`
`elasticsearch.url`	`http://elasticsearch:9200`
`elasticsearch.username`	`elastic`
`elasticsearch.password`	`changeme`
`xpack.monitoring.ui.container.elasticsearch.enabled`	`true`

These settings are defined in the default kibana.yml. They can be overridden with a custom kibana.yml or via environment variables.
