Chainguard Container for kube-fluentd-operator

This image is used for the Kubernetes Fluentd Operator

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/kube-fluentd-operator:latest

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

Compatibility Notes

Chainguard's kube-fluentd-operator container image is comparable to the official kube-fluentd-operator image.

Notably, Chainguard's kube-fluentd-operator image does not expose any ports whereas the ports exported by the upstream are: 24444/tcp and 5140/tcp. Additionally, like other Chainguard Containers, kube-fluentd-operator does not include things like a shell or package manager.

Getting Started

Install using helm:

Create a values.yaml file with the following values:

rbac:
  create: true

image:
  tag: latest
  repository: cgr.dev/<ORGANIZATION>/kube-fluentd-operator

Make sure to replace the ORGANIZATION with your desired values.

Install using the new values:

git clone git@github.com:vmware/kube-fluentd-operator.git
helm install kfo ./kube-fluentd-operator/charts/log-router \
  -f values.yaml \
  --wait

Then create a namespace demo and a configmap describing where all logs from demo should go to. The configmap must contain an entry called fluent.conf. Finally, point the kube-fluentd-operator to this configmap using annotations.

kubectl create ns demo

cat > fluent.conf << EOF
<match **>
  @type null
</match>
EOF

Create the configmap with a single entry "fluent.conf":

kubectl create configmap fluentd-config --namespace demo --from-file=fluent.conf=fluent.conf

In a minute, this configuration would be translated to something like this:

<match demo.**>
  @type null
</match>

Documentation and Resources

What are Chainguard Containers?

Chainguard's free tier of Starter container images are built with Wolfi, our minimal Linux undistro.

All other Chainguard Containers are built with Chainguard OS, Chainguard's minimal Linux operating system designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

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

In all other cases, including Chainguard Containers tagged as :latest or with a specific version number, the container images include only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager.

Although the -dev container image variants have similar security features as their more minimal versions, they include additional software that is typically not necessary in production environments. We recommend using multi-stage builds to copy artifacts from the -dev variant into a more minimal production image.

Need additional packages?

To improve security, Chainguard Containers include only essential dependencies. Need more packages? Chainguard customers can use Custom Assembly to add packages, either through the Console, chainctl, or API.

To use Custom Assembly in the Chainguard Console: navigate to the image you'd like to customize in your Organization's list of images, and click on the Customize image button at the top of the page.
