Customize your cluster configuration

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

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'

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'

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:

kubectl apply \
  --filename myinfluxdb.yml \
  --namespace influxdb
helm upgrade \
  influxdata/influxdb3-clustered \
  -f ./values.yml \
  --namespace influxdb

New in InfluxDB 3.5

Key enhancements in InfluxDB 3.5 and the InfluxDB 3 Explorer 1.3.

See the Blog Post

InfluxDB 3.5 is now available for both Core and Enterprise, introducing custom plugin repository support, enhanced operational visibility with queryable CLI parameters and manual node management, stronger security controls, and general performance improvements.

InfluxDB 3 Explorer 1.3 brings powerful new capabilities including Dashboards (beta) for saving and organizing your favorite queries, and cache querying for instant access to Last Value and Distinct Value caches—making Explorer a more comprehensive workspace for time series monitoring and analysis.

InfluxDB Docker latest tag changing to InfluxDB 3 Core

On November 3, 2025, the latest tag for InfluxDB Docker images will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments.

If using Docker to install and run InfluxDB, the latest tag will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments. For example, if using Docker to run InfluxDB v2, replace the latest version tag with a specific version tag in your Docker pull command–for example:

docker pull influxdb:2
