## Introduction

This chart bootstraps a [Elasticsearch](https://github.com/bitnami/containers/tree/main/bitnami/elasticsearch) deployment on a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.

Bitnami charts can be used with [Kubeapps](https://kubeapps.dev/) for deployment and management of Helm Charts in clusters.

## Prerequisites

- Kubernetes 1.23+
- Helm 3.8.0+
- PV provisioner support in the underlying infrastructure

## Installing the Chart

To install the chart with the release name `my-release`:

```console
helm install my-release oci://REGISTRY_NAME/REPOSITORY_NAME/elasticsearch
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

These commands deploy Elasticsearch on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.

> **Tip**: List all releases using `helm list`

## Configuration and installation details

### Resource requests and limits

Bitnami charts allow setting resource requests and limits for all containers inside the chart deployment. These are inside the `resources` value (check parameter table). Setting requests is essential for production workloads and these should be adapted to your specific use case.

To make this process easier, the chart contains the `resourcesPreset` values, which automatically sets the `resources` section according to different presets. Check these presets in [the bitnami/common chart](https://github.com/bitnami/charts/blob/main/bitnami/common/templates/_resources.tpl#L15). However, in production workloads using `resourcePreset` is discouraged as it may not fully adapt to your specific needs. Find more information on container resource management in the [official Kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/).

### [Rolling VS Immutable tags](https://docs.bitnami.com/tutorials/understand-rolling-tags-containers)

It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.

Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.

### Change ElasticSearch version

To modify the ElasticSearch version used in this chart you can specify a [valid image tag](https://hub.docker.com/r/bitnami/elasticsearch/tags/) using the `image.tag` parameter. For example, `image.tag=X.Y.Z`. This approach is also applicable to other images like exporters.

### Default kernel settings

Currently, Elasticsearch requires some changes in the kernel of the host machine to work as expected. If those values are not set in the underlying operating system, the ES containers fail to boot with ERROR messages. More information about these requirements can be found in the links below:

- [File Descriptor requirements](https://www.elastic.co/guide/en/elasticsearch/reference/current/file-descriptors.html)
- [Virtual memory requirements](https://www.elastic.co/guide/en/elasticsearch/reference/current/vm-max-map-count.html)

This chart uses a **privileged** initContainer to change those settings in the Kernel by running: `sysctl -w vm.max_map_count=262144 && sysctl -w fs.file-max=65536`.
You can disable the initContainer using the `sysctlImage.enabled=false` parameter.

### Enable bundled Kibana

This Elasticsearch chart contains Kibana as subchart, you can enable it just setting the `global.kibanaEnabled=true` parameter.
To see the notes with some operational instructions from the Kibana chart, please use the `--render-subchart-notes` as part of your `helm install` command, in this way you can see the Kibana and ES notes in your terminal.

When enabling the bundled kibana subchart, there are a few gotchas that you should be aware of listed below.

#### Elasticsearch rest Encryption

When enabling elasticsearch' rest endpoint encryption you will also need to set `kibana.elasticsearch.security.tls.enabled` to the SAME value along with some additional values shown below for an "out of the box experience":

```yaml
security:
  enabled: true
  # PASSWORD must be the same value passed to elasticsearch to get an "out of the box" experience
  elasticPassword: "<PASSWORD>"
  tls:
    # AutoGenerate TLS certs for elastic
    autoGenerated: true

kibana:
  elasticsearch:
    security:
      auth:
        enabled: true
        # default in the elasticsearch chart is elastic
        kibanaUsername: "<USERNAME>"
        kibanaPassword: "<PASSWORD>"
      tls:
        # Instruct kibana to connect to elastic over https
        enabled: true
        # Bit of a catch 22, as you will need to know the name upfront of your release
        existingSecret: RELEASENAME-elasticsearch-coordinating-crt # or just 'elasticsearch-coordinating-crt' if the release name happens to be 'elasticsearch'
        # As the certs are auto-generated, they are pemCerts so set to true
        usePemCerts: true
```

At a bare-minimum, when working with kibana and elasticsearch together the following values MUST be the same, otherwise things will fail:

```yaml
security:
  tls:
    restEncryption: true

# assumes global.kibanaEnabled=true
kibana:
  elasticsearch:
    security:
      tls:
        enabled: true
```

### How to deploy a single node

This chart allows you to deploy Elasticsearch as a "single-node" cluster (one master node replica) that assumes all the roles. The following inputs should be provided:

```yaml
master:
  masterOnly: false
  replicaCount: 1
data:
  replicaCount: 0
coordinating:
  replicaCount: 0
ingest:
  replicaCount: 0
```

The "single-node" cluster will be configured with [single-node discovery](https://www.elastic.co/guide/en/elasticsearch/reference/current/bootstrap-checks.html#single-node-discovery).

If you want to scale up to more replicas, make sure you refresh the configuration of the existing StatefulSet. For example, scale down to 0 replicas first to avoid inconsistencies in the configuration:

```console
kubectl scale statefulset <DEPLOYMENT_NAME>-master --replicas=0
helm upgrade <DEPLOYMENT_NAME> oci://REGISTRY_NAME/REPOSITORY_NAME/elasticsearch --reset-values --set master.masterOnly=false
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

Please note that the master nodes should continue assuming all the roles (`master.masterOnly: false`) since there is shard data on the first replica.

### Adding extra environment variables

In case you want to add extra environment variables (useful for advanced operations like custom init scripts), you can use the `extraEnvVars` property.

```yaml
extraEnvVars:
  - name: ELASTICSEARCH_VERSION
    value: 7.0
```

Alternatively, you can use a ConfigMap or a Secret with the environment variables. To do so, use the `extraEnvVarsCM` or the `extraEnvVarsSecret` values.

### Using custom init scripts

For advanced operations, the Bitnami Elasticsearch charts allows using custom init scripts that will be mounted inside `/docker-entrypoint.init-db`. You can include the file directly in your `values.yaml` with `initScripts`, or use a ConfigMap or a Secret (in case of sensitive data) for mounting these extra scripts. In this case you use the `initScriptsCM` and `initScriptsSecret` values.

```console
initScriptsCM=special-scripts
initScriptsSecret=special-scripts-sensitive
```

### Snapshot and restore operations

As it's described in the [official documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/snapshots-register-repository.html#snapshots-filesystem-repository), it's necessary to register a snapshot repository before you can perform snapshot and restore operations.

This chart allows you to configure Elasticsearch to use a shared file system to store snapshots. To do so, you need to mount a RWX volume on every Elasticsearch node, and set the parameter `snapshotRepoPath` with the path where the volume is mounted. In the example below, you can find the values to set when using a NFS Perstitent Volume:

```yaml
extraVolumes:
  - name: snapshot-repository
    nfs:
      server: nfs.example.com # Please change this to your NFS server
      path: /share1
extraVolumeMounts:
  - name: snapshot-repository
    mountPath: /snapshots
snapshotRepoPath: "/snapshots"
```

### Sidecars and Init Containers

If you have a need for additional containers to run within the same pod as Elasticsearch components (e.g. an additional metrics or logging exporter), you can do so via the `XXX.sidecars` parameter(s), where XXX is placeholder you need to replace with the actual component(s). Simply define your container according to the Kubernetes container spec.

```yaml
sidecars:
  - name: your-image-name
    image: your-image
    imagePullPolicy: Always
    ports:
      - name: portname
        containerPort: 1234
```

Similarly, you can add extra init containers using the `initContainers` parameter.

```yaml
initContainers:
  - name: your-image-name
    image: your-image
    imagePullPolicy: Always
    ports:
      - name: portname
```

### Setting Pod's affinity

This chart allows you to set your custom affinity using the `XXX.affinity` parameter(s). Find more information about Pod's affinity in the [kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity).

As an alternative, you can use of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the [bitnami/common](https://github.com/bitnami/charts/tree/main/bitnami/common#affinities) chart. To do so, set the `XXX.podAffinityPreset`, `XXX.podAntiAffinityPreset`, or `XXX.nodeAffinityPreset` parameters.

## Persistence

The [Bitnami Elasticsearch](https://github.com/bitnami/containers/tree/main/bitnami/elasticsearch) image stores the Elasticsearch data at the `/bitnami/elasticsearch/data` path of the container.

By default, the chart mounts a [Persistent Volume](https://kubernetes.io/docs/concepts/storage/persistent-volumes/) at this location. The volume is created using dynamic volume provisioning. See the [Parameters](#parameters) section to configure the PVC.

### Adjust permissions of persistent volume mountpoint

As the image run as non-root by default, it is necessary to adjust the ownership of the persistent volume so that the container can write data into it.

By default, the chart is configured to use Kubernetes Security Context to automatically change the ownership of the volume. However, this feature does not work in all Kubernetes distributions.
As an alternative, this chart supports using an initContainer to change the ownership of the volume before mounting it in the final destination.

You can enable this initContainer by setting `volumePermissions.enabled` to `true`.

### Kibana Parameters

| Name                         | Description                                                               | Value                                                   |
| ---------------------------- | ------------------------------------------------------------------------- | ------------------------------------------------------- |
| `kibana.elasticsearch.hosts` | Array containing hostnames for the ES instances. Used to generate the URL | `[]`                                                    |
| `kibana.elasticsearch.port`  | Port to connect Kibana and ES instance. Used to generate the URL          | `{{ include "elasticsearch.service.ports.restAPI" . }}` |

Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,

```console
helm install my-release \
  --set name=my-elastic,client.service.port=8080 \
  oci://REGISTRY_NAME/REPOSITORY_NAME/elasticsearch
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

The above command sets the Elasticsearch cluster name to `my-elastic` and REST port number to `8080`.

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

```console
helm install my-release -f values.yaml oci://REGISTRY_NAME/REPOSITORY_NAME/elasticsearch
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.
> **Tip**: You can use the default [values.yaml](https://github.com/bitnami/charts/tree/main/bitnami/elasticsearch/values.yaml).

## To 20.0.0

This major bump changes the following security defaults:

- `runAsGroup` is changed from `0` to `1001`
- `readOnlyRootFilesystem` is set to `true`
- `resourcesPreset` is changed from `none` to the minimum size working in our test suites (NOTE: `resourcesPreset` is not meant for production usage, but `resources` adapted to your use case).
- `global.compatibility.openshift.adaptSecurityContext` is changed from `disabled` to `auto`.

This could potentially break any customization or init scripts used in your deployment. If this is the case, change the default values to the previous ones.

### To 19.6.0

This version fixes the headless services creation. When upgrading you will need to manually delete the services first in order to get them created when upgrading.

### To 19.0.0

The new version of this chart no longer supports elasticsearch-curator, this repository has been deprecated.

### To 18.0.0

This major release refactors the bitnami/elasticsearch chart, adding some organization and functional changes.

- Each role has now the same structure: its Statefulset, a headless service (for FQDN, it gives each node an individual Advertised name, required for TLS verification), its own ServiceAccount (BWC), and HorizontalPodAutoscaling.
- Previously, the chart would alternate between a Coordinating service and an All-nodes service for traffic exposure. This logic has been replaced with a single Traffic exposure service, that will have coordinating-only nodes as backend pods, or master pods if no coordinating nodes are enabled.
- Master-eligible nodes can now be deployed as multi-role nodes using the setting masterOnly. This allows the creation of different topologies, smaller clusters with HA (3 multi-role master-eligible nodes), and single-node deployments.
- Renamed several values to be in line with the rest of the catalog.

This major release also upgrades Elasticsearch to its version 8.x.x and the updates Kibana subchart.

- Upgrade to Elasticsearch 8
- Upgrade Kibana subchart.

In addition, several modifications have been performed adding missing features and renaming values, in order to get aligned with the rest of the assets in the Bitnami charts repository.

The following values have been modified:

- `coordinating.service.*` have been renamed as `service.*`. This service will be backed by coordinating nodes if enabled, or master nodes if not.
- `master.service.*` has been removed.
- `data.service.*` has been removed.
- `master.ingress.*` has been renamed as `ingress.*`. This ingress will be backed by the coordinating/master service previously mentioned.
- In addition, an Ingest-only service and ingress have been added, for use cases where separated ingrestion and search channels are needed.
- `global.coordinating.name` have been renamed as `global.elasticsaerch.service.name`.
- `name` has been renamed as `clusterName`.
- `extraEnvVarsConfigMap` has been renamed as `extraEnvVarsCM`.
- `{master/data/ingest/coordinating}.replicas` has been renamed as `{master/data/ingest/coordinating}.replicaCount`.
- `{master/data/ingest/coordinating}.securityContext` has been separated in two different values: `podSecurityContext` and `containerSecurityContext`.
- `{master/data/ingest/coordinating}.updateStrategy` is now interpreted as an object. `rollingUpdatePartition` has been removed and has to be configured inside the updateStrategy object when needed.
- Default values for `kibana.elasticsearch.hosts` and `kibana.elasticsearch.port` have been modified to use the new helpers.
- `{master/data/ingest/coordinating/curator/metrics}.name` has been renamed as `{master/data/ingest/coordinating/curator}.nameOverride`.

### To 17.0.0

This version bumps in a major the version of the Kibana Helm Chart bundled as dependecy, [here](https://github.com/bitnami/charts/tree/main/bitnami/kibana#to-900) you can see the changes implemented in this Kibana major version.

### To 16.0.0

This version replaces the Ingest and Coordinating Deployments with Statefulsets. This change is required so Coordinating and Ingest nodes have their services associated, required for TLS hostname verification.

We haven't encountered any issues during our upgrade test, but we recommend creating volumes backups before upgrading this major version, especially for users with additional volumes and custom configurations.

Additionally, this version adds support for X-Pack Security features such as TLS/SSL encryption and basic authentication.

### To 15.0.0

From this version onwards, Elasticsearch container components are now licensed under the [Elastic License](https://www.elastic.co/licensing/elastic-license) that is not currently accepted as an Open Source license by the Open Source Initiative (OSI).

Also, from now on, the Helm Chart will include the X-Pack plugin installed by default.

Regular upgrade is compatible from previous versions.

### To 14.0.0

This version standardizes the way of defining Ingress rules in the Kibana subchart. When configuring a single hostname for the Ingress rule, set the `kibana.ingress.hostname` value. When defining more than one, set the `kibana.ingress.extraHosts` array. Apart from this case, no issues are expected to appear when upgrading.

### To 13.0.0

[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.

#### What changes were introduced in this major version?

- Previous versions of this Helm Chart use `apiVersion: v1` (installable by both Helm 2 and 3), this Helm Chart was updated to `apiVersion: v2` (installable by Helm 3 only). [Here](https://helm.sh/docs/topics/charts/#the-apiversion-field) you can find more information about the `apiVersion` field.
- Move dependency information from the *requirements.yaml* to the *Chart.yaml*
- After running `helm dependency update`, a *Chart.lock* file is generated containing the same structure used in the previous *requirements.lock*
- The different fields present in the *Chart.yaml* file has been ordered alphabetically in a homogeneous way for all the Bitnami Helm Charts

#### Considerations when upgrading to this version

- If you want to upgrade to this version from a previous one installed with Helm v3, you shouldn't face any issues
- If you want to upgrade to this version using Helm v2, this scenario is not supported as this version doesn't support Helm v2 anymore
- If you installed the previous version with Helm v2 and wants to upgrade to this version with Helm v3, please refer to the [official Helm documentation](https://helm.sh/docs/topics/v2_v3_migration/#migration-use-cases) about migrating from Helm v2 to v3

### To 12.0.0

Several changes were introduced that breaks backwards compatibility:

- Ports names were prefixed with the protocol to comply with Istio (see <https://istio.io/docs/ops/deployment/requirements/>).
- Labels are adapted to follow the Helm charts best practices.
- Elasticsearch data pods are now deployed in parallel in order to bootstrap the cluster and be discovered.

### To 11.0.0

Elasticsearch master pods are now deployed in parallel in order to bootstrap the cluster and be discovered.

The field `podManagementPolicy` can't be updated in a StatefulSet, so you need to destroy it before you upgrade the chart to this version.

```console
kubectl delete statefulset elasticsearch-master
helm upgrade <DEPLOYMENT_NAME> oci://REGISTRY_NAME/REPOSITORY_NAME/elasticsearch
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

### TO 10.0.0

In this version, Kibana was added as dependent chart. More info about how to enable and work with this bundled Kibana in the ["Enable bundled Kibana"](#enable-bundled-kibana) section.

### To 9.0.0

Elasticsearch master nodes store the cluster status at `/bitnami/elasticsearch/data`. Among other things this includes the UUID of the elasticsearch cluster. Without a persistent data store for this data, the UUID of a cluster could change if k8s node(s) hosting the es master nodes go down and are scheduled on some other master node. In the event that this happens, the data nodes will no longer be able to join a cluster as the uuid changed resulting in a broken cluster.

To resolve such issues, PVC's are now attached for master node data persistence.

---

Helm performs a lookup for the object based on its group (apps), version (v1), and kind (Deployment). Also known as its GroupVersionKind, or GVK. Changing the GVK is considered a compatibility breaker from Kubernetes' point of view, so you cannot "upgrade" those objects to the new GVK in-place. Earlier versions of Helm 3 did not perform the lookup correctly which has since been fixed to match the spec.

In [4dfac075aacf74405e31ae5b27df4369e84eb0b0](https://github.com/bitnami/charts/commit/4dfac075aacf74405e31ae5b27df4369e84eb0b0) the `apiVersion` of the deployment resources was updated to `apps/v1` in tune with the api's deprecated, resulting in compatibility breakage.

### To 7.4.0

This version also introduces `bitnami/common`, a [library chart](https://helm.sh/docs/topics/library_charts/#helm) as a dependency. More documentation about this new utility could be found [here](https://github.com/bitnami/charts/tree/main/bitnami/common#bitnami-common-library-chart). Please, make sure that you have updated the chart dependencies before executing any upgrade.

### To 7.0.0

This version enabled by default the initContainer that modify some kernel settings to meet the Elasticsearch requirements. More info in the ["Default kernel settings"](#default-kernel-settings) section.
You can disable the initContainer using the `sysctlImage.enabled=false` parameter.

### To 3.0.0

Backwards compatibility is not guaranteed unless you modify the labels used on the chart's deployments.
Use the workaround below to upgrade from versions previous to 3.0.0. The following example assumes that the release name is elasticsearch:

```console
kubectl patch deployment elasticsearch-coordinating --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
kubectl patch deployment elasticsearch-ingest --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
kubectl patch deployment elasticsearch-master --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
kubectl patch deployment elasticsearch-metrics --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
kubectl delete statefulset elasticsearch-data --cascade=false
```
