Chainguard Container for eck-operator

Elastic Cloud on Kubernetes

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/eck-operator:latest

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

Usage

There are several ways to deploy the ECK operator. You can follow up the Quickstart guide or you can use the Helm Chart available in Artifact Hub to deploy the operator.

The following example is going to show how to deploy the ECK operator using a its Helm Chart.

Deploy the ECK operator using Helm

1. Add the Elastic Helm repository:

helm repo add elastic https://helm.elastic.co

2. Install the ECK operator:

helm install elastic-operator elastic/eck-operator --namespace elastic-system --set image.repository=cgr.dev/chainguard/eck-operator --set image.tag=latest

Deploy an Elasticsearch cluster

1. Create a file called elasticsearch.yaml with the following content:

apiVersion: elasticsearch.k8s.elastic.co/v1
kind: Elasticsearch
metadata:
  name: quickstart
spec:
  version: 8.13.3
  nodeSets:
  - name: default
    count: 1
    config:
      node.store.allow_mmap: false

2. Deploy the Elasticsearch cluster:

kubectl apply -f elasticsearch.yaml

3. Check the Elasticsearch cluster status:

kubectl get elasticsearch quickstart -o=jsonpath='{.status.phase}'

4. Access the Elasticsearch cluster:

kubectl port-forward service/quickstart-es-http 9200

5. Get the password for the elastic user:

PASSWORD=$(kubectl get secret quickstart-es-elastic-user -o=jsonpath='{.data.elastic}' | base64 --decode)

6. Access the Elasticsearch cluster using curl:

curl -u "elastic:$PASSWORD" -k "https://localhost:9200"

That's it! You have deployed an Elasticsearch cluster using the ECK operator.

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.
