Download this Container Image

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

docker pull cgr.dev/ORGANIZATION/clickhouse-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

Chaingaurd's Clickhouse Operator container image is comparable to the clickhouse operator image. Like most other Chainguard container images, the Clickhouse Operator container image contains only the dependencies it needs to function, and doesn't include things like a shell or package manager.

Getting Started

The Chainguard's Clickhouse Operator container image can be installed via the clickhouse-operator helm chart.

Create a values.yaml file with the following values

operator:
  image:
    repository: cgr.dev/ORGANIZATION/clickhouse-operator
    tag: latest

Make sure to replace ORGANIZATION with your organization.

Run the following command to install the helm chart:

helm repo add clickhouse-operator https://github.com/Altinity/clickhouse-operator
helm install https://github.com/Altinity/clickhouse-operator deploy/helm -f values.yaml

We can then try creating a basic ClickHouse Cluster with the following manifest:

apiVersion: "clickhouse.altinity.com/v1"
kind: "ClickHouseInstallation"
metadata:
  name: "simple-01"
spec:
  configuration:
    users:
      # printf 'test_password' | sha256sum
      test_user/password_sha256_hex: 10a6e6cc8311a3e2bcc09bf6c199adecd5dd59408c343e926b129c4914f3cb01
      test_user/password: test_password
      # to allow access outside from kubernetes
      test_user/networks/ip:
        - 0.0.0.0/0
    clusters:
      - name: "simple"

Once cluster is created, we can verify it by running the following command:

kubectl get pods -n test-clickhouse-operator
NAME                    READY   STATUS    RESTARTS   AGE
chi-b3d29f-a242-0-0-0   1/1     Running   0          10m

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.
