This listing has an open-source license. InfluxDB&trade; and InfluxDB Relay&trade; are run and maintained by InfluxData, which is a completely separate project from Bitnami.

## TL;DR

```console
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/influxdb
```

## Introduction

This chart bootstraps a [influxdb](https://github.com/bitnami/bitnami-docker-influxdb) 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.com/) for deployment and management of Helm Charts in clusters.

## Prerequisites

- Kubernetes 1.19+
- Helm 3.2.0+
- PV provisioner support in the underlying infrastructure
- ReadWriteMany volumes for deployment scaling

## Installing the Chart

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

```console
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/influxdb
```

These commands deploy influxdb 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`

## Uninstalling the Chart

To uninstall/delete the `my-release` statefulset:

```console
$ helm delete my-release
```

The command removes all the Kubernetes components associated with the chart and deletes the release. Use the option `--purge` to delete all history too.

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

```console
$ helm install my-release \
  --set auth.admin.username=admin-user bitnami/influxdb
```

The above command sets the InfluxDB&trade; admin user to `admin-user`.

> NOTE: Once this chart is deployed, it is not possible to change the application's access credentials, such as usernames or passwords, using Helm. To change these application credentials after deployment, delete any persistent volumes (PVs) used by the chart and re-deploy it, or use the application's built-in administrative tools if available.

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 bitnami/influxdb
```

> **Tip**: You can use the default [values.yaml](values.yaml)

## Configuration and installation details

### [Rolling VS Immutable tags](https://docs.bitnami.com/containers/how-to/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.

## Standalone vs High Availability architecture

You can install the InfluxDB&trade; chart with two different architecture setups: "standalone" or "high-availability", you can use the `architecture` parameter:

```console
architecture="standalone"
architecture="high-availability"
```

The standalone architecture installs a deployment with one InfluxDB&trade; server (it cannot be scaled):

When using the high-availability architecture, it is recommended to configure sticky sessions using `--set influxdb.service.sessionAffinity="ClientIP"` or configuring the IngressController accordingly.

### Configure the way how to expose InfluxDB&trade;

- **Ingress**: The ingress controller must be installed in the Kubernetes cluster. Set `ingress.enabled=true` to expose InfluxDB&trade; through Ingress.
- **ClusterIP**: Exposes the service on a cluster-internal IP. Choosing this value makes the service only reachable from within the cluster. Set `influxdb.service.type=ClusterIP` to choose this service type.
- **NodePort**: Exposes the service on each Node's IP at a static port (the NodePort). You'll be able to contact the NodePort service, from outside the cluster, by requesting `NodeIP:NodePort`. Set `influxdb.service.type=NodePort` to choose this service type.
- **LoadBalancer**: Exposes the service externally using a cloud provider's load balancer. Set `influxdb.service.type=LoadBalancer` to choose this service type.

### Using custom configuration

This helm chart supports to customize the whole configuration file.

Add your custom configuration file to "files/conf" in your working directory. This file will be mounted as a configMap to the containers and it will be used for configuring InfluxDB&trade;.

Alternatively, you can specify the InfluxDB&trade; configuration using the `influxdb.configuration` parameter.

In addition to these options, you can also set an external ConfigMap with all the configuration files. This is done by setting the `influxdb.existingConfiguration` parameter. Note that this will override the two previous options.

### Adding extra environment variables

In case you want to add extra environment variables, you can use the `influxdb.extraEnvVars` property.

```yaml
extraEnvVars:
  - name: INFLUXDB_DATA_QUERY_LOG_ENABLED
    value: "true"
```

### Initialize a fresh instance

The [Bitnami InfluxDB&trade;](https://github.com/bitnami/bitnami-docker-influxdb) image allows you to use your custom scripts to initialize a fresh instance. In order to execute the scripts, they must be located inside the chart folder `files/docker-entrypoint-initdb.d` so they can be consumed as a ConfigMap.

Alternatively, you can specify custom scripts using the `influxdb.initdbScripts` parameter.

In addition to these options, you can also set an external ConfigMap with all the initialization scripts. This is done by setting the `influxdb.initdbScriptsCM` parameter. Note that this will override the two previous options. parameter.

The allowed extensions are `.sh`, and `.txt`.

### 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/master/bitnami/common#affinities) chart. To do so, set the `XXX.podAffinityPreset`, `XXX.podAntiAffinityPreset`, or `XXX.nodeAffinityPreset` parameters.

## Persistence

The data is persisted by default using PVC(s). You can disable the persistence setting the `persistence.enabled` parameter to `false`.
A default `StorageClass` is needed in the Kubernetes cluster to dynamically provision the volumes. Specify another StorageClass in the `persistence.storageClass` or set `persistence.existingClaim` if you have already existing persistent volumes to use.

### Adjust permissions of persistent volume mountpoint

As the images run as non-root by default, it is necessary to adjust the ownership of the persistent volumes so that the containers 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`.
There are K8s distribution, such as OpenShift, where you can dynamically define the UID to run this **initContainer**. To do so, set the `volumePermissions.securityContext.runAsUser` to `auto`.

## Upgrade

It's necessary to specify the existing passwords while performing an upgrade to ensure the secrets are not updated with invalid randomly generated passwords. Remember to specify the existing values of the `auth.admin.password`, `user.pwd`, ` auth.readUser.password` and `auth.writeUser.password` parameters when upgrading the chart:

```bash
$ helm upgrade my-release bitnami/influxdb \
    --set auth.admin.password=[ADMIN_USER_PASSWORD] \
    --set auth.user.password=[USER_PASSWORD] \
    --set auth.readUser.password=[READ_USER_PASSWORD] \
    --set auth.writeUser.password=[WRITE_USER_PASSWORD]
```

> Note: you need to substitute the placeholders _[ADMIN_USER_PASSWORD]_, _[USER_PASSWORD]_, _[READ_USER_PASSWORD]_, and _[WRITE_USER_PASSWORD]_ with the values obtained from instructions in the installation notes.

## Upgrading

### To 3.0.0

This major release renames several values in this chart and adds missing features, in order to be inline with the rest of assets in the Bitnami charts repository.

Affected values:

- `influxdb.service.port` was deprecated, we recommend using `influxdb.service.ports.http` instead.
- `influxdb.service.rpcPort` was deprecated, we recommend using `influxdb.service.ports.rpc` instead.
- `relay.service.port` was deprecated, we recommend using `relay.service.ports.http` instead.
- `relay.service.nodePort` was renamed as `relay.service.nodePorts.http`.
- `influxdb.securityContext` split into `influxdb.containerSecurityContext` and `influxdb.podSecurityContext`.
- `relay.securityContext` split into `relay.containerSecurityContext` and `relay.podSecurityContext`.
- `influxdb.updateStrategy` and `relay.updateStrategy`changed from String type (previously default to 'rollingUpdate') to Object type, allowing users to configure other updateStrategy parameters, similar to other charts.

### To 2.0.0

This version adds support to InfluxDB&trade; +2.0, since this version the chart is only verified to work with InfluxDB&trade; +2.0 bitnami images.
However, you can use images for versions ~1.x.x taking into account the chart may need some modification to run with them.

#### Installing InfluxDB&trade; v1 in chart v2.

```
$ helm install bitnami/influxdb --set image.tag=1.8.3-debian-10-r88
```

As a consecuece some breaking changes have been included in this version.

- Authentication values has been moved to `auth.<property>...`.
- We keep `auth.readUser` and `auth.writeUser` user options in order to be compatible with InfluxDB&trade; v1. If you are using InfluxDB&trade; 2.0, please, use the CLI to create user and tokens through initDb scripts at `influxdb.initdbScripts` or the UI due to we are not able to automacally provide a token for them to be used. See more [InfluxDB&trade; 2.0 auth](https://docs.influxdata.com/influxdb/v2.0/security/tokens/)
- InfluxDB&trade; 2.0 has removed database concept, now it is called Bucket so the property `database` has been also moved to `auth.user.bucket`.
- Removed support for `files/docker-entrypoint-initdb.d/*.{sh,txt}`, please use `.influxdb.initdbScripts` or `.Values.influxdb.initdbScriptsCM` instead.
- Removed support for `files/conf/influxdb.conf`, please use `.influxdb.configuration` or `.influxdb.existingConfiguration` instead.
- Removed support for `files/conf/relay.toml`, please use `.Values.relay.configuration` or `.Values.relay.existingConfiguration` instead.
- `ingress.hosts` parameter has been replaced by `ingress.hostname` and `ingress.extraHosts` that may give us a bit more flexibility.

#### Migrating form InfluxDB&trade; v1 to v2

Since this release could mean lot of concepts changes, we strongly recommend to not do it direcly using the chart upgrade. Please, read more info in their [upgrade guide](https://docs.influxdata.com/influxdb/v2.0/upgrade/v1-to-v2/).

We actually recommend to backup all the data form a previous helm release, install new release using latest version of the chart and images and then restore data following their guides.

#### Upgrading the chart form 1.x.x to 2.x.x using InfluxDB&trade; v1 images.

> NOTE: Please, create a backup of your database before running any of those actions.

Having an already existing chart release called `influxdb` and deployed like

```console
$ helm install influxdb bitnami/influxdb
```

##### Export secrets and required values to update

```console
$ export INFLUXDB_ADMIN_PASSWORD=$(kubectl get secret --namespace default influxdb -o jsonpath="{.data.admin-user-password}" | base64 --decode)
```

##### Upgrade the chart release

> NOTE: Please remember to migrate all the values to its new path following the above notes, e.g: `adminUser.pwd` -> `auth.admin.password`.

```console
$ helm upgrade influxdb bitnami/influxdb --set image.tag=1.8.3-debian-10-r99 \
  --set auth.admin.password=${INFLUXDB_ADMIN_PASSWORD}
```

### To 1.1.0

This version 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/master/bitnami/common#bitnami-common-library-chart). Please, make sure that you have updated the chart dependencies before executing any upgrade.

### To 1.0.0

[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.
- 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
