## TL;DR

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

## Introduction

Bitnami charts for Helm are carefully engineered, actively maintained and are the quickest and easiest way to deploy containers on a Kubernetes cluster that are ready to handle production workloads.

This chart bootstraps a [Grafana Tempo](https://github.com/grafana/tempo) Deployment in 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.

[Learn more about the default configuration of the chart](https://docs.bitnami.com/kubernetes/infrastructure/grafana-tempo/get-started/).

## Prerequisites

- Kubernetes 1.19+
- Helm 3.2.0+
- PV provisioner support in the underlying infrastructure

## Installing the Chart

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

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

The command deploys grafana-tempo 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` deployment:

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

The command removes all the Kubernetes components associated with the chart and deletes the release.

See <https://github.com/bitnami-labs/readme-generator-for-helm> to create the table

The above parameters map to the env variables defined in [bitnami/grafana-tempo](https://github.com/bitnami/containers/tree/main/bitnami/grafana-tempo). For more information please refer to the [bitnami/grafana-tempo](https://github.com/bitnami/containers/tree/main/bitnami/grafana-tempo) image documentation.

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

```console
$ helm install my-release \
  --set tempo.traces.jaeger.grpc=true \
  my-repo/grafana-tempo
```

The above command enables the Jaeger GRPC traces.

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

```console
helm install my-release -f values.yaml my-repo/grafana-tempo
```

> **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.

### Tempo configuration

The tempo configuration file `tempo.yaml` is shared across the different components: `distributor`, `compactor`, `ingester`, `querier` and `queryFrontend`. This is set in the `tempo.configuration` value. Check the official [Tempo Grafana documentation](https://grafana.com/docs/tempo/latest/configuration/) for the list of possible configurations.

## Persistence

The [Bitnami grafana-tempo](https://github.com/bitnami/containers/tree/main/bitnami/grafana-tempo) image stores the grafana-tempo `ingester` data at the `/bitnami` path of the container. Persistent Volume Claims are used to keep the data across deployments.

### Additional 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 inside each of the subsections: `distributor`, `compactor`, `ingester`, `querier`, `queryFrontend` and `vulture`.

```yaml
compactor:
  extraEnvVars:
    - name: LOG_LEVEL
      value: error

distributor:
  extraEnvVars:
    - name: LOG_LEVEL
      value: error

ingester:
  extraEnvVars:
    - name: LOG_LEVEL
      value: error

querier:
  extraEnvVars:
    - name: LOG_LEVEL
      value: error

queryFrontend:
  extraEnvVars:
    - name: LOG_LEVEL
      value: error

vulture:
  extraEnvVars:
    - name: LOG_LEVEL
      value: error
```

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

### Sidecars

If additional containers are needed in the same pod as grafana-tempo (such as additional metrics or logging exporters), they can be defined using the `sidecars` parameter inside each of the subsections: `distributor`, `compactor`, `ingester`, `querier`, `queryFrontend` and `vulture` . If these sidecars export extra ports, extra port definitions can be added using the `service.extraPorts` parameter. [Learn more about configuring and using sidecar containers](https://docs.bitnami.com/kubernetes/infrastructure/grafana-tempo/configuration/configure-sidecar-init-containers/).

### Pod affinity

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

As an alternative, use one 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 `podAffinityPreset`, `podAntiAffinityPreset`, or `nodeAffinityPreset` parameters inside each of the subsections: `distributor`, `compactor`, `ingester`, `querier`, `queryFrontend` and `vulture`.

### External cache support

You may want to have Grafana Tempo connect to an external Memcached rather than installing one inside your cluster. Typical reasons for this are to use a managed cache service, or to share a common cache server for all your applications. To achieve this, the chart allows you to specify credentials for an external database with the [`externalMemcached` parameter](#parameters). You should also disable the Memcached installation with the `memcached.enabled` option. Here is an example:

```console
memcached.enabled=false
externalMemcached.host=myexternalhost
externalMemcached.port=11211
```

## Upgrading

### To 1.0.0

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.

- `tempo.containerPort`, `tempo.grpcContainerPort` and `tempo.gossipRing.containerPort` have been regrouped under the `tempo.containerPorts` map.
- `queryFrontend.query.jaegerMetricsContainerPort` and `queryFrontend.query.jaegerUIContainerPort` have been regrouped under the `queryFrontend.query.containerPorts` map.
- `vulture.containerPort` has been regrouped under the `vulture.containerPorts` map.
- `XXX.service.port` and `XXX.service.grpcPort` have been regrouped under the `XXX.service.ports` map.

Additionally updates the Memcached subchart to its newest major `6.x.x`, which contains similar changes.
