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"}}]}' ``` ## Contributing Please check [CONTRIBUTING.md][] before any contribution or for any questions about our development and testing process.
