Chainguard Container for grafana-rollout-operator-fips

Kubernetes Rollout Operator coordinates the rollout of pods between different StatefulSets within a specific namespace, and can be used to manage multi-AZ deployments

Chainguard Containers are regularly-updated, secure-by-default container images.

Download this Container Image

For those with access, this container image is available on cgr.dev:

docker pull cgr.dev/ORGANIZATION/grafana-rollout-operator-fips:latest

Be sure to replace the ORGANIZATION placeholder with the name used for your organization's private repository within the Chainguard Registry.

Compatibility Notes

This image is the FIPS version of Chainguard's Grafan Rollout Operator image, which is itself a drop-in replacement for the grafana/rollout-operator image.

Getting Started

There is a Helm chart available for the Grafana Rollout Operator. You can install it using the following commands:

First, install the Helm chart repository:

helm repo add grafana https://grafana.github.io/helm-charts
helm repo update

Prepare the values file values.yaml with the following content:

 image:
   repository: cgr.dev/ORGANIZATION/grafana-rollout-operator-fips
   tag: latest

Then, install the Grafana Rollout Operator:

helm install grafana-rollout-operator grafana/grafana-rollout-operator -f values.yaml

Check the daemonset is running:

kubectl get deploy grafana-rollout-operator -n grafana-rollout-operator

This works in conjencture with mimir-distributed.

Add Labels and Annotations to ingester zones:

kubectl label sts mimir-ingester-zone-a grafana.com/min-time-between-zones-downscale=2m -n mimir
kubectl label sts mimir-ingester-zone-a grafana.com/prepare-downscale=true -n mimir
kubectl annotate sts mimir-ingester-zone-a grafana.com/prepare-downscale-http-path=ingester/prepare-shutdown -n mimir
kubectl annotate sts mimir-ingester-zone-a grafana.com/prepare-downscale-http-port=80 -n mimir

kubectl label sts mimir-ingester-zone-b grafana.com/min-time-between-zones-downscale=2m -n mimir
kubectl label sts mimir-ingester-zone-b grafana.com/prepare-downscale=true -n mimir
kubectl annotate sts mimir-ingester-zone-b grafana.com/rollout-downscale-leader=mimir-ingester-zone-a -n mimir
kubectl annotate sts mimir-ingester-zone-b grafana.com/prepare-downscale-http-path=ingester/prepare-shutdown -n mimir
kubectl annotate sts mimir-ingester-zone-b grafana.com/prepare-downscale-http-port=80 -n mimir

kubectl label sts mimir-ingester-zone-c grafana.com/min-time-between-zones-downscale=2m -n mimir
kubectl label sts mimir-ingester-zone-c grafana.com/prepare-downscale=true -n mimir
kubectl annotate sts mimir-ingester-zone-c grafana.com/rollout-downscale-leader=mimir-ingester-zone-b -n mimir
kubectl annotate sts mimir-ingester-zone-c grafana.com/prepare-downscale-http-path=ingester/prepare-shutdown -n mimir
kubectl annotate sts mimir-ingester-zone-c grafana.com/prepare-downscale-http-port=80 -n mimir

Check for logs:

kubectl logs deployment/mimir-rollout-operator -n mimir

This command will return output like the following:

What are Chainguard Containers?

Chainguard Containers are minimal container images that are secure by default.

In many cases, the Chainguard Containers tagged as :latest contain only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager. Chainguard Containers are built with Wolfi, our Linux undistro designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

• Minimal design, without unnecessary software bloat
• Daily builds to ensure container images are up-to-date with available security patches
• High quality build-time SBOMs attesting to the provenance of all artifacts within the image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a -dev variant.

Although the -dev container image variants have similar security features as their more minimal versions, they feature additional software that is typically not necessary in production environments. We recommend using multi-stage builds to leverage the -dev variants, copying application artifacts into a final minimal container that offers a reduced attack surface that won’t allow package installations or logins.
