Helm Deployment Security FAQs

Question 1

What is the best way to handle secrets in Helm?

Accepted Answer

It is best practice to avoid storing secrets in plain text values.yaml. Instead, use the helm-secrets plugin for encryption or integrate with external secret providers like AWS Secrets Manager or HashiCorp Vault.

Question 2

Why should I use image digests instead of tags in Helm charts?

Accepted Answer

Using image digests (e.g., sha256:...) ensures immutability. Unlike tags, which can be overwritten or pointed to different images, a digest guarantees that the exact same code is deployed every time, preventing supply chain attacks.

Question 3

How do I verify the integrity of a Helm chart?

Accepted Answer

You can verify chart integrity by using GPG keys to sign the package and running the 'helm verify' command with the corresponding keyring to ensure the provenance of the chart has not been tampered with.

Question 4

What tools can I use to scan Helm templates for vulnerabilities?

Accepted Answer

The skill provides patterns for using tools like kubesec, checkov, trivy, and kube-linter to scan rendered templates for security misconfigurations before they are applied to a cluster.
