Running Kibana on Docker
editRunning Kibana on Docker
editDocker images for Kibana are available from the Elastic Docker registry. The base image is centos:7.
A list of all published Docker images and tags is available at www.docker.elastic.co. The source code is in GitHub.
These images are free to use under the Elastic license. They contain open source and free commercial features and access to paid commercial features. Start a 30-day trial to try out all of the paid commercial features. See the Subscriptions page for information about Elastic license levels.
Pulling the image
editObtaining Kibana for Docker is as simple as issuing a docker pull
command
against the Elastic Docker registry.
docker pull docker.elastic.co/kibana/kibana:6.6.2
Alternatively, you can download other Docker images that contain only features available under the Apache 2.0 license. To download the images, go to www.docker.elastic.co.
Configuring Kibana on Docker
editThe Docker images provide 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
editOne 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:
version: '2' services: kibana: image: docker.elastic.co/kibana/kibana:6.6.2 volumes: - ./kibana.yml:/usr/share/kibana/config/kibana.yml
Environment variable configuration
editUnder Docker, Kibana can be configured via environment variables. When the container starts, a helper process checks the environment for variables that can be mapped to Kibana command-line arguments.
For compatibility with container orchestration systems, these environment variables are written in all capitals, with underscores as word separators. The helper translates these names to valid Kibana setting names.
Some example translations are shown here:
Table 1. Example Docker Environment Variables

Kibana Setting |
|
|
|
|
|
|
In general, any setting listed in Configuring Kibana or X-Pack Settings can be configured with this technique.
These variables can be set with docker-compose
like this:
version: '2' services: kibana: image: docker.elastic.co/kibana/kibana:6.6.2 environment: SERVER_NAME: kibana.example.org ELASTICSEARCH_HOSTS: http://elasticsearch.example.org
Since environment variables are translated to CLI arguments, they take
precedence over settings configured in kibana.yml
.
Docker defaults
editThe following settings have different default values when using the Docker images:
|
|
|
|
|
|
|
|
The setting xpack.monitoring.ui.container.elasticsearch.enabled
is not
defined in the -oss
image.
These settings are defined in the default kibana.yml
. They can be overridden
with a custom kibana.yml
or via
environment variables.
If replacing kibana.yml
with a custom version, be sure to copy the
above defaults to the custom file if you want to retain them. If not, they will
be "masked" by the new file.
