This is a Kubernetes Operator to provision and inject secrets for Kubernetes pods. Compared to Kubernetes' native secret mounts, this permits secrets to be selected dynamically based on properties of the Pod.

It is part of the Stackable Data Platform, a curated selection of the best open source data apps like Apache Kafka, Apache Druid, Trino or Apache Spark, all working together seamlessly. Based on Kubernetes, it runs everywhere – on prem or in the cloud.

You can install the operator using stackablectl or helm.

Read on to get started with it, or see it in action in one of our demos.

As a user you do not need to build the operator yourself, but for development purposes you can read the build instructions to learn how to build the operator.

You can follow this tutorial .

The stable documentation for this operator can be found here. If you are interested in the most recent state of this repository, check out the nightly docs instead.

The Secret Operator provisions and mounts secrets, but unlike the default Kubernetes Secret mechanism, Secrets can be created and mounted dynamically based on Pod properties. The Operator supports:

• Generating TLS certificates on demand and mounting them

The Secret Operator is deployed as a DaemonSet and provides a CSI to mount files directly into Pods.
