Securing Helm Chart Deployments
Overview
Helm is the Kubernetes package manager. Securing Helm deployments requires validating chart provenance, scanning templates for security misconfigurations, enforcing pod security contexts, managing secrets securely, and controlling RBAC for Helm operations.
When to Use
Trigger phrases:
-
"securing helm chart deployments"
-
"Secure Helm chart deployments by validating chart integrity, scanning templates "
-
When deploying or configuring securing helm chart deployments capabilities in your environment
-
When establishing security controls aligned to compliance requirements
-
When building or improving security architecture for this domain
-
When conducting security assessments that require this implementation
Prerequisites
- Helm 3.12+ installed
- kubectl with cluster access
- GnuPG for chart signing/verification
- kubesec or checkov for template scanning
Chart Provenance and Integrity
This section covers chart provenance and integrity for securing helm chart deployments.
- Ensure all prerequisites are met before proceeding
- Follow the documented workflow steps in sequence
- Record results and any anomalies encountered during this phase
Sign a Helm Chart
gpg --full-generate-key
helm package ./mychart --sign --key "helm-signing@example.com" --keyring ~/.gnupg/pubring.gpg
helm verify mychart-0.1.0.tgz --keyring ~/.gnupg/pubring.gpg
Verify Chart Before Install
helm pull myrepo/mychart --verify --keyring /path/to/keyring.gpg
cat mychart-0.1.0.tgz.prov
Template Security Scanning
This section covers template security scanning for securing helm chart deployments.
- Ensure all prerequisites are met before proceeding
- Follow the documented workflow steps in sequence
- Record results and any anomalies encountered during this phase
