# Elasticsearch Helm Chart
|
||||
|
||||
This chart uses a standard Docker image of Elasticsearch (docker.elastic.co/elasticsearch/elasticsearch-oss) and uses a service pointing to the master's transport port for service discovery.
|
||||
Elasticsearch does not communicate with the Kubernetes API, hence no need for RBAC permissions.
|
||||
|
||||
## Warning for previous users
|
||||
If you are currently using an earlier version of this Chart you will need to redeploy your Elasticsearch clusters. The discovery method used here is incompatible with using RBAC.
|
||||
If you are upgrading to Elasticsearch 6 from the 5.5 version used in this chart before, please note that your cluster needs to do a full cluster restart.
|
||||
The simplest way to do that is to delete the installation (keep the PVs) and install this chart again with the new version.
|
||||
If you want to avoid doing that upgrade to Elasticsearch 5.6 first before moving on to Elasticsearch 6.0.
|
||||
|
||||
## Prerequisites Details
|
||||
|
||||
* Kubernetes 1.6+
|
||||
* PV dynamic provisioning support on the underlying infrastructure
|
||||
|
||||
## StatefulSets Details
|
||||
* https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/
|
||||
|
||||
## StatefulSets Caveats
|
||||
* https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/#limitations
|
||||
|
||||
## Todo
|
||||
|
||||
* Implement TLS/Auth/Security
|
||||
* Smarter upscaling/downscaling
|
||||
* Solution for memory locking
|
||||
|
||||
## Chart Details
|
||||
This chart will do the following:
|
||||
|
||||
* Implemented a dynamically scalable elasticsearch cluster using Kubernetes StatefulSets/Deployments
|
||||
* Multi-role deployment: master, client (coordinating) and data nodes
|
||||
* Statefulset Supports scaling down without degrading the cluster
|
||||
|
||||
## Installing the Chart
|
||||
|
||||
To install the chart with the release name `my-release`:
|
||||
|
||||
```bash
|
||||
$ helm install --name my-release stable/elasticsearch
|
||||
```
|
||||
|
||||
## Deleting the Charts
|
||||
|
||||
Delete the Helm deployment as normal
|
||||
|
||||
```
|
||||
$ helm delete my-release
|
||||
```
|
||||
|
||||
Deletion of the StatefulSet doesn't cascade to deleting associated PVCs. To delete them:
|
||||
|
||||
```
|
||||
$ kubectl delete pvc -l release=my-release,component=data
|
||||
```
|
||||
|
||||

|

In terms of Memory resources you should make sure that you follow that equation:
|
||||
|
||||
- `${role}HeapSize < ${role}MemoryRequests < ${role}MemoryLimits`
|
||||
|
||||
The YAML value of cluster.config is appended to elasticsearch.yml file for additional customization ("script.inline: on" for example to allow inline scripting)
|
||||
|
||||
# Deep dive
|
||||
|
||||
## Application Version
|
||||
|
||||
This chart aims to support Elasticsearch v2 to v6 deployments by specifying the `values.yaml` parameter `appVersion`.
|
||||
|
||||
### Version Specific Features
|
||||
|
||||
* Memory Locking *(variable renamed)*
|
||||
* Ingest Node *(v5)*
|
||||
* X-Pack Plugin *(v5)*
|
||||
|
||||
Upgrade paths & more info: https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-upgrade.html
|
||||
|
||||
## Mlocking
|
||||
|
||||
This is a limitation in kubernetes right now. There is no way to raise the
|
||||
limits of lockable memory, so that these memory areas won't be swapped. This
|
||||
would degrade performance heavily. The issue is tracked in
|
||||
[kubernetes/#3595](https://github.com/kubernetes/kubernetes/issues/3595).
|
||||
|
||||
```
|
||||
[WARN ][bootstrap] Unable to lock JVM Memory: error=12,reason=Cannot allocate memory
|
||||
[WARN ][bootstrap] This can result in part of the JVM being swapped out.
|
||||
[WARN ][bootstrap] Increase RLIMIT_MEMLOCK, soft limit: 65536, hard limit: 65536
|
||||
```
|
||||
|
||||
## Minimum Master Nodes
|
||||
> The minimum_master_nodes setting is extremely important to the stability of your cluster. This setting helps prevent split brains, the existence of two masters in a single cluster.
|
||||
|
||||
>When you have a split brain, your cluster is at danger of losing data. Because the master is considered the supreme ruler of the cluster, it decides when new indices can be created, how shards are moved, and so forth. If you have two masters, data integrity becomes perilous, since you have two nodes that think they are in charge.
|
||||
|
||||
>This setting tells Elasticsearch to not elect a master unless there are enough master-eligible nodes available. Only then will an election take place.
|
||||
|
||||
>This setting should always be configured to a quorum (majority) of your master-eligible nodes. A quorum is (number of master-eligible nodes / 2) + 1
|
||||
|
||||
More info: https://www.elastic.co/guide/en/elasticsearch/guide/1.x/_important_configuration_changes.html#_minimum_master_nodes
|
||||
|
||||
# Client and Coordinating Nodes
|
||||
|
||||
Elasticsearch v5 terminology has updated, and now refers to a `Client Node` as a `Coordinating Node`.
|
||||
|
||||
More info: https://www.elastic.co/guide/en/elasticsearch/reference/5.5/modules-node.html#coordinating-node
|
||||
|
||||
## Enabling elasticsearch interal monitoring
|
||||
Requires version 6.3+ and standard non `oss` repository defined. Starting with 6.3 Xpack is partially free and enabled by default. You need to set a new config to enable the collection of these internal metrics. (https://www.elastic.co/guide/en/elasticsearch/reference/6.3/monitoring-settings.html)
|
||||
|
||||
To do this through this helm chart override with the three following changes:
|
||||
```
|
||||
image.repository: docker.elastic.co/elasticsearch/elasticsearch
|
||||
cluster.xpackEnable: true
|
||||
cluster.env.XPACK_MONITORING_ENABLED: true
|
||||
```
|
||||
|
||||
Note: to see these changes you will need to update your kibana repo to `image.repository: docker.elastic.co/kibana/kibana` instead of the `oss` version
|
||||
|
||||
|
||||
## Select right storage class for SSD volumes
|
||||
|
||||
### GCE + Kubernetes 1.5
|
||||
|
||||
Create StorageClass for SSD-PD
|
||||
|
||||
```
|
||||
$ kubectl create -f - <<EOF
|
||||
kind: StorageClass
|
||||
apiVersion: extensions/v1beta1
|
||||
metadata:
|
||||
name: ssd
|
||||
provisioner: kubernetes.io/gce-pd
|
||||
parameters:
|
||||
type: pd-ssd
|
||||
EOF
|
||||
```
|
||||
Create cluster with Storage class `ssd` on Kubernetes 1.5+
|
||||
|
||||
```
|
||||
$ helm install stable/elasticsearch --name my-release --set data.storageClass=ssd,data.storage=100Gi
|
||||
```
|
||||
|
||||
### Usage of the `tpl` Function
|
||||
|
||||
The `tpl` function allows us to pass string values from `values.yaml` through the templating engine. It is used for the following values:
|
||||
|
||||
* `extraInitContainers`
|
||||
|
||||
It is important that these values be configured as strings. Otherwise, installation will fail.

The elasticsearch cluster has been installed.

WARNING: You have likely exposed your Elasticsearch cluster direct to the internet.

Elasticsearch does not implement any security for public facing clusters by default.

As a minimum level of security; switch to ClusterIP/NodePort and place an Nginx gateway infront of the cluster in order to lock down access to dangerous HTTP endpoints and verbs.

NOTE: It may take a few minutes for the LoadBalancer IP to be available.
