== Running Kibana on Docker
|
|
Docker images for Kibana are available from the Elastic Docker registry. The
|
|
base image is https://hub.docker.com/_/centos/[centos:7].
|
|
|
|
A list of all published Docker images and tags can be found at
|
|
https://www.docker.elastic.co[www.docker.elastic.co]. The source code can be
|
|
found on https://github.com/elastic/elasticsearch-docker/tree/{branch}[GitHub].
|
|
|
|
=== Image types
|
|
|
|
The images are available in two different configurations or "flavors". The
|
|
`x-pack` flavor, which is the default, ships with X-Pack features
|
|
pre-installed. The `oss` flavor does not include X-Pack, and contains only
|
|
open source Kibana.
|
|
|
|
NOTE: https://www.elastic.co/guide/en/x-pack/current/index.html[X-Pack] is
|
|
pre-installed in the default image. With X-Pack installed, Kibana expects to
|
|
connect to an Elasticsearch cluster that is also running X-Pack.
|
|
|
|
=== Pulling the image
|
|
Obtaining Kibana for Docker is as simple as issuing a +docker pull+ command
|
|
against the Elastic Docker registry.
|
|
|
|
ifeval::["{release-state}"=="unreleased"]
|
|
|
|
However, version {version} of Kibana has not yet been released, so no Docker
|
|
image is currently available for this version.
|
|
|
|
endif::[]
|
|
|
|
ifeval::["{release-state}"!="unreleased"]
|
|
|
|
Docker images can be retrieved with the following commands:
|
|
|
|
["source","txt",subs="attributes"]
|
|
--------------------------------------------
|
|
docker pull {docker-repo}:{version}
|
|
docker pull {docker-repo}-oss:{version}
|
|
--------------------------------------------
|
|
|
|
endif::[]
|
|
|
|
=== Configuring Kibana on Docker
|
|
|
|
The Docker images provide several methods for configuring Kibana. The
|
|
conventional approach is to provide a `kibana.yml` file as described in
|
|
{kibana-ref}/settings.html[Configuring Kibana], but it's also possible to use
|
|
environment variables to define settings.
|
|
|
|
[[docker-bind-mount-config]]
|
|
==== Bind-mounted configuration
|
|
|
|
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:
|
|
|
|
["source","yaml",subs="attributes"]
|
|
--------------------------------------------
|
|
version: '2'
|
|
services:
|
|
kibana:
|
|
image: {docker-image}
|
|
volumes:
|
|
- ./kibana.yml:/usr/share/kibana/config/kibana.yml
|
|
--------------------------------------------
|
|
|
|
[[docker-env-config]]
|
|
==== Environment variable configuration
|
|
|
|
Under 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:
|
|
|
|
.Example Docker Environment Variables
|
|
[horizontal]
|
|
**Environment Variable**:: **Kibana Setting**
|
|
`SERVER_NAME`:: `server.name`
|
|
`KIBANA_DEFAULTAPPID`:: `kibana.defaultAppId`
|
|
`XPACK_MONITORING_ENABLED`:: `xpack.monitoring.enabled`
|
|
|
|
In general, any setting listed in <<settings>> or
|
|
{xpack-ref}/xpack-settings.html[X-Pack Settings] can be configured
|
|
with this technique.
|
|
|
|
These variables can be set with +docker-compose+ like this:
|
|
|
|
["source","yaml",subs="attributes"]
|
|
----------------------------------------------------------
|
|
version: '2'
|
|
services:
|
|
kibana:
|
|
image: {docker-image}
|
|
environment:
|
|
SERVER_NAME: kibana.example.org
|
|
ELASTICSEARCH_URL: http://elasticsearch.example.org
|
|
----------------------------------------------------------
|
|
|
|
Since environment variables are translated to CLI arguments, they take
|
|
precedence over settings configured in `kibana.yml`.
|
|
|
|
==== Docker defaults
|
|
The following settings have different default values when using the Docker
|
|
images:
|
|
|
|
[horizontal]
|
|
`server.name`:: `kibana`
|
|
`server.host`:: `"0"`
|
|
`elasticsearch.url`:: `http://elasticsearch:9200`
|
|
|
|
In the `x-pack` image, the following additional defaults are also set:
|
|
|
|
[horizontal]
|
|
`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 <<docker-bind-mount-config,custom `kibana.yml`>> or via
|
|
<<docker-env-config,environment variables>>.
|
|
|
|
IMPORTANT: 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.
