This image contains the loki application for log aggregation. loki can be used to stream, aggregate, and query logs from apps and infrastructure.

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/loki:latest

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

Compatibility Notes

Loki is comprised of 2 images:

cgr.dev/ORGANIZATION/loki cgr.dev/ORGANIZATION/loki-canary

The Chainguard images usually do not run as the root user and contain only the minimum set of tools and dependencies needed to function. This means they do not include utilities such as a shell or a package manager.

Getting Started

We can use helm charts for testing dapr images. We can create a values.yaml that'll override upstream images with Chainguard images.

loki:
  image:
    registry: cgr.dev
    repository: ORGANIZATION/loki
    tag: latest

lokiCanary:
    image:
        registry: cgr.dev
        repository: ORGANIZATION/loki-canary
        tag: latest

After that we can do the following to install the chart in our cluster.

helm repo add grafana https://grafana.github.io/helm-charts
helm repo update
helm install loki grafana/loki -f values.yaml --wait

We can then validate if the loki and loki-canary pods are up using the following command:

kubectl get pods -n loki-system

You should see the loki and loki-canary pods up and running:

/ # kubectl get pods -n loki-system

NAME                            READY   STATUS    RESTARTS   AGE
loki-0                          2/2     Running   0          45h
loki-canary-5crfb               1/1     Running   0          45h
loki-gateway-6c9dc9b78c-2tqmq   1/1     Running   0          45h
loki-results-cache-0            2/2     Running   0          45h

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:

• 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 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.
