Terraform Helm InfluxDB v2 Module

A Terraform module to deploy InfluxDB v2 on a Kubernetes Cluster using the Helm Provider.

Default Admin Password & Token

If the admin_password or admin-token input variables are not set, the initial password & token for the admin user account are auto-generated and stored as clear text in the admin-password and admin-token fields of a secret named influxdb2-auth¹ in your InfluxDB installation namespace (influxdb by default). You can retrieve these values via the kubectl command:

kubectl -n influxdb get secret influxdb2-auth -o jsonpath="{.data.admin-password}" | base64 -d; echo

Substitute admin-password in the above command with admin-token to retrieve the default Admin user token.
