Kibana Helm Chart

This Helm chart is a lightweight way to configure and run our official Kibana Docker image.

Warning: This branch is used for development, please use 7.8.1 release for supported version.

Requirements

  • Helm >=2.8.0 and <3.0.0
  • Kubernetes >=1.9

See supported configurations for more details.

Installing

Install released version using Helm repository

  • Add the Elastic Helm charts repo: helm repo add elastic https://helm.elastic.co

  • Install it:

    • with Helm 2: helm install --name kibana elastic/kibana
    • with Helm 3 (beta): helm install kibana elastic/kibana

Install development version using master branch

  • Clone the git repo: git clone git@github.com:elastic/helm-charts.git

  • Install it:

    • with Helm 2: helm install --name kibana ./helm-charts/kibana --set imageTag=8.0.0-SNAPSHOT
    • with Helm 3 (beta): helm install kibana ./helm-charts/kibana --set imageTag=8.0.0-SNAPSHOT

Upgrading

Please always check CHANGELOG.md and BREAKING_CHANGES.md before upgrading to a new chart version.

Usage notes

  • Automated testing of this chart is currently only run against GKE (Google Kubernetes Engine).

  • This repo includes a number of examples configurations which can be used as a reference. They are also used in the automated testing of this chart.

Configuration

Parameter Description Default
affinity Configurable affinity {}
elasticsearchHosts The URLs used to connect to Elasticsearch http://elasticsearch-master:9200
envFrom Templatable string to be passed to the environment from variables which will be appended to the envFrom: definition for the container []
extraContainers Templatable string of additional containers to be passed to the tpl function ""
extraEnvs Extra environment variables which will be appended to the env: definition for the container see values.yaml
extraInitContainers Templatable string of additional containers to be passed to the tpl function ""
fullnameOverride Overrides the full name of the resources. If not set the name will default to " .Release.Name - .Values.nameOverride orChart.Name " ""
healthCheckPath The path used for the readinessProbe to check that Kibana is ready. If you are setting server.basePath you will also need to update this to /${basePath}/app/kibana /app/kibana
httpPort The http port that Kubernetes will use for the healthchecks and the service 5601
imagePullPolicy The Kubernetes imagePullPolicyvalue IfNotPresent
imagePullSecrets Configuration for imagePullSecrets so that you can use a private registry for your image []
imageTag The Kibana Docker image tag 8.0.0-SNAPSHOT
image The Kibana Docker image docker.elastic.co/kibana/kibana
ingress Configurable ingress to expose the Kibana service. see values.yaml
kibanaConfig Allows you to add any config files in /usr/share/kibana/config/ such as kibana.yml See values.yaml for an example of the formatting {}
labels Configurable labels applied to all Kibana pods {}
lifecycle Allows you to add lifecycle hooks. See values.yaml for an example of the formatting {}
nameOverride Overrides the chart name for resources. If not set the name will default to .Chart.Name ""
nodeSelector Configurable nodeSelector so that you can target specific nodes for your Kibana instances {}
podAnnotations Configurable annotations applied to all Kibana pods {}
podSecurityContext Allows you to set the securityContext for the pod see values.yaml
priorityClassName The name of the PriorityClass. No default is supplied as the PriorityClass must be created first ""
protocol The protocol that will be used for the readinessProbe. Change this to https if you have server.ssl.enabled: true set http
readinessProbe Configuration for the readiness probe see values.yaml
replicas Kubernetes replica count for the Deployment (i.e. how many pods) 1
resources Allows you to set the resources for the Deployment see values.yaml
secretMounts Allows you easily mount a secret as a file inside the Deployment. Useful for mounting certificates and other secrets. See values.yaml for an example []
securityContext Allows you to set the securityContext for the container see values.yaml
serverHost The server.host Kibana setting. This is set explicitly so that the default always matches what comes with the Docker image 0.0.0.0
serviceAccount Allows you to overwrite the "default" serviceAccount for the pod []
service Configurable service to expose the Kibana service. see values.yaml
tolerations Configurable tolerations) []
updateStrategy Allows you to change the default updateStrategy for the Deployment. A standard upgrade of Kibana requires a full stop and start which is why the default strategy is set to Recreate type: Recreate

Deprecated

Parameter Description Default
elasticsearchURL The URL used to connect to Elasticsearch. needs to be used for Kibana versions < 6.6 ""

FAQ

How to deploy this chart on a specific K8S distribution?

This chart is highly tested with GKE, but some K8S distribution also requires specific configurations.

We provide examples of configuration for the following K8S providers:

How to use Kibana with security (authentication and TLS) enabled?

This Helm chart can use existing Kubernetes secrets to setup credentials or certificates for examples. These secrets should be created outside of this chart and accessed using environment variables and volumes.

An example can be found in examples/security.

How to install OSS version of Kibana?

Deploying OSS version of Elasticsearch can be done by setting image value to kibana OSS Docker image

An example of Kibana deployment using OSS version can be found in examples/oss.

How to install plugins?

The recommended way to install plugins into our Docker images is to create a custom Docker image.

The Dockerfile would look something like:

ARG kibana_version
FROM docker.elastic.co/kibana/kibana:${kibana_version}

RUN bin/kibana-plugin install <plugin_url>

And then updating the image in values to point to your custom image.

There are a couple reasons we recommend this:

  1. Tying the availability of Kibana to the download service to install plugins is not a great idea or something that we recommend. Especially in Kubernetes where it is normal and expected for a container to be moved to another host at random times.
  2. Mutating the state of a running Docker image (by installing plugins) goes against best practices of containers and immutable infrastructure.

How to import objects post-deployment?

You can use postStart lifecycle hooks to run code triggered after a container is created.

Here is an example of postStart hook to import an index-pattern and a dashboard:

lifecycle:
  postStart:
    exec:
      command:
        - bash
        - -c
        - |
          #!/bin/bash
          # Import a dashboard
          KB_URL=http://localhost:5601
          while [[ "$(curl -s -o /dev/null -w '%{http_code}\n' -L $KB_URL)" != "200" ]]; do sleep 1; done
          curl -XPOST "$KB_URL/api/kibana/dashboards/import" -H "Content-Type: application/json" -H 'kbn-xsrf: true' -d'"objects":[{"type":"index-pattern","id":"my-pattern","attributes":{"title":"my-pattern-*"}},{"type":"dashboard","id":"my-dashboard","attributes":{"title":"Look at my dashboard"}}]}'
