Exam CKS Topic 2 Question 57 Discussion

Actual exam question for Linux Foundation's CKS exam
Question #: 57
Topic #: 2
You are using a third-party Helm chart to deploy an application to your Kubernetes cluster. You need to ensure that the Helm chart adheres to security best practices and does not introduce any vulnerabilities into your cluster. Implement a solution that uses KubeLinter to statically analyze the Helm chart before deployment.

Suggested Answer:

Solution (Step by Step):
1. Install KubeLinter: Download and install the 'kubevar binary from the official GitHub repository.
2. Render the Helm chart: use the 'helm template' command to render the Helm chart into Kubernetes YAML manifests.
bash
helm template my-chart -f values.yaml > rendered-templates.yaml
3. Validate the rendered YAML manifests using KubeLinter Use the 'kubevar command to validate the rendered YAML manifests against the
Kubernetes schema and your custom rules.
bash
kubeval rendered-templates.yaml
4. Integrate KubeLinter into your CI/CD pipeline: Add a step to your pipeline that renders the Helm chart and runs KubeLinter against the rendered
YAML manifests. This step should be executed before the chart is deployed.
