# Kibana Helm Chart

[![Build Status](https://img.shields.io/jenkins/s/https/devops-ci.elastic.co/job/elastic+helm-charts+master.svg)](https://devops-ci.elastic.co/job/elastic+helm-charts+master/) [![Artifact HUB](https://img.shields.io/endpoint?url=https://artifacthub.io/badge/repository/elastic)](https://artifacthub.io/packages/search?repo=elastic)

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

## Requirements

* Kubernetes >= 1.14
* [Helm][] >= 2.17.0

See [supported configurations][] for more details.

## Installing

This chart is tested with the latest 7.17.3 version.

### Install released version using Helm repository

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

* Install it:
  - with Helm 3: `helm install kibana --version <version> elastic/kibana`
  - with Helm 2 (deprecated): `helm install --name kibana --version <version> elastic/kibana`

### Install development version from a branch

* Clone the git repo: `git clone [email protected]:elastic/helm-charts.git`

* Checkout the branch : `git checkout 7.17`

* Install it:
  - with Helm 3: `helm install kibana ./helm-charts/kibana --set imageTag=7.17.3`
  - with Helm 2 (deprecated): `helm install --name kibana ./helm-charts/kibana --set imageTag=7.17.3`


## 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.

## 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:

- [OpenShift][]

### 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 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:

```yaml
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"}}]}'
```
