Use environment variables to customize configuration options for components in your InfluxDB cluster.

{{< tabs-wrapper >}} {{% tabs "medium" %}} AppInstance Helm {{% /tabs %}}

{{% tab-content %}}

In your AppInstance resource, configure environment variables for individual components in the spec.package.spec.components.<component>.template.containers.iox.env property. The following InfluxDB Clustered components are configurable:

• ingester
• querier
• router
• compactor
• garbage-collector

In the env property, structure each environment variable as a key-value pair where the key is the environment variable name and the value is the environment variable value (string-formatted)--for example:

apiVersion: kubecfg.dev/v1alpha1
kind: AppInstance
metadata:
  name: influxdb
  namespace: influxdb
spec:
  package:
    # ...
    spec:
      components:
        router:
          template:
            containers:
              iox:
                env:
                  INFLUXDB_IOX_MAX_HTTP_REQUESTS: '4500'
                  INFLUXDB_IOX_MAX_HTTP_REQUEST_SIZE: '52428800'

{{% /tab-content %}} {{% tab-content %}}

In your values.yaml, configure environment variables for individual components in the components.<component>.template.containers.iox.env property. The following InfluxDB Clustered components are configurable:

• ingester
• querier
• router
• compactor
• garbage-collector

In the env property, structure each environment variable as a key-value pair where the key is the environment variable name and the value is the environment variable value (string-formatted)--for example:

components:
  router:
    template:
      containers:
        iox:
          env:
            INFLUXDB_IOX_MAX_HTTP_REQUESTS: '4500'
            INFLUXDB_IOX_MAX_HTTP_REQUEST_SIZE: '52428800'

{{% /tab-content %}} {{< /tabs-wrapper >}}

Configurable settings

For information about what settings are configurable and their associated environment variables, contact InfluxData Support.

Apply the changes to your cluster

Use kubectl or helm (if using the InfluxDB Clustered Helm chart), to apply the changes to your cluster:

{{< code-tabs-wrapper >}} {{% code-tabs %}} kubectl Helm {{% /code-tabs %}} {{% code-tab-content %}}

kubectl apply \
  --filename myinfluxdb.yml \
  --namespace influxdb

{{% /code-tab-content %}} {{% code-tab-content %}}

helm upgrade \
  influxdata/influxdb3-clustered \
  -f ./values.yml \
  --namespace influxdb

{{% /code-tab-content %}} {{< /code-tabs-wrapper >}}
