One of the simplest ways to get started with Apache Flink on Kubernetes is to use the Flink Kubernetes Operator provided by the Apache Flink community. The Flink Kubernetes Operator is a Kubernetes custom controller that simplifies the deployment and management of Apache Flink applications on Kubernetes.
The following example shows how to deploy Apache Flink on Kubernetes using the Flink Kubernetes Operator.
Install the Flink Kubernetes Operator by following the instructions in the Flink Kubernetes Operator documentation.
Create a FlinkDeployment resource to deploy Apache Flink on Kubernetes. The following example shows a basic FlinkDeployment resource that deploys a Flink job using the StateMachineExample.jar example JAR file.

Chainguard Images are a collection of container images designed for security and minimalism.
Many Chainguard Images are distroless; they contain only an open-source application and its runtime dependencies. These images do not even contain a shell or package manager. Chainguard Images are built with Wolfi, our Linux undistro designed to produce container images that meet the requirements of a secure software supply chain.
The main features of Chainguard Images include:
-dev
VariantsAs mentioned previously, Chainguard’s distroless Images have no shell or package manager by default. This is great for security, but sometimes you need these things, especially in builder images. For those cases, most (but not all) Chainguard Images come paired with a -dev
variant which does include a shell and package manager.
Although the -dev
image variants have similar security features as their distroless versions, such as complete SBOMs and signatures, they feature additional software that is typically not necessary in production environments. The general recommendation is to use the -dev
variants only to build the application and then copy all application artifacts into a distroless image, which will result in a final container image that has a minimal attack surface and won’t allow package installations or logins.
That being said, it’s worth noting that -dev
variants of Chainguard Images are completely fine to run in production environments. After all, the -dev
variants are still more secure than many popular container images based on fully-featured operating systems such as Debian and Ubuntu since they carry less software, follow a more frequent patch cadence, and offer attestations for what they include.
