Helm Security Challenges

Helm simplifies Kubernetes deployments but introduces security concerns: untrusted charts, unprotected secrets, and supply chain risks.

Chart Signing

Sign charts with GPG to verify authenticity:

Generate signing key

gpg --full-generate-key

gpg --list-secret-keys

Sign a chart

helm package mychart/

helm sign mychart-1.0.0.tgz --key " [email protected] "

Verify a chart

helm verify mychart-1.0.0.tgz

With custom public key

gpg --export [email protected] > pubkey.asc

helm verify mychart-1.0.0.tgz --keyring pubkey.asc

Provenance Files

Provenance files contain the chart hash and signature:

mychart-1.0.0.tgz.prov

apiVersion:…
