Install the chart

Deploy to Kubernetes with hardened defaults. The chart pins its image by signed digest, so you never track it yourself.

Install (pinned to 0.0.2)

helm install my-step-issuer oci://ghcr.io/quenchworks/charts/step-issuer --version 0.0.2

Chart version: 0.0.2
Chart license: Apache-2.0
App license: Apache-2.0
Signed: cosign (keyless)
Released: 2026-10-05

Verify the chart

cosign verify ghcr.io/quenchworks/charts/step-issuer:0.0.2 \
  --certificate-identity-regexp 'https://github.com/quenchworks/.+' \
  --certificate-oidc-issuer https://token.actions.githubusercontent.com

Transparency

The chart publishes its attestations on GitHub and the image it deploys carries its own on the same digest, publicly verifiable with the commands above. Both log to the Sigstore transparency log (Rekor), which cosign verify checks for you.
