spire VS cosign

If this seems a bit complicated, you could use SPIRE server to issue certificates and Otterize SPIRE integration operator to renew them in Kubernetes and update Secrets.

The effort to get this going seems the same or more than to get something like this rolling out. spire what do you see as the benefit of your approach.

Cosign: In this context, Cosign from the Sigstore project offers a compelling solution. Its simplicity, registry compatibility, and effective link between images and their signatures provide a user-friendly and versatile approach. The integration of Fulcio for certificate management and Rekor for secure logging enhances Cosign's appeal, making it particularly suitable for modern development environments that prioritize security and agility.

sigstore is another suite of tools that focuses on attestation and provenance. Within the suite are two tools I heard mentioned a few times at KubeCon: Cosign and Rekor.

Since we can distribute Spin applications using popular registry services, we can also take advantage of ecosystem tools such as Sigstore and Cosign, which address the software supply chain issue by signing and verifying applications using Sigstore's new keyless signatures (using OIDC identity tokens from providers such as GitHub).

Use distroless images (which contain only application and its runtime dependencies, and don't include package managers/shells or any other programs you would expect to find in a standard Linux distribution). All distroless images are signed by cosign.

$ COSIGN_EXPERIMENTAL=1 cosign verify-blob --cert https://github.com/sigstore/cosign/releases/download/v1.13.1/cosign-linux-amd64-keyless.pem --signature https://github.com/sigstore/cosign/releases/download/v1.13.1/cosign-linux-amd64-keyless.sig https://github.com/sigstore/cosign/releases/download/v1.13.1/cosign-linux-amd64

Another thing to look for is, whether the image is signed using something like cosign (https://github.com/sigstore/cosign). This lets the publisher digitally sign the image, so you at least know that what's on the registry is what they intended to put there. Handy to avoid the risks of attackers squatting similar names and catching typos.

i’m late but surprised no one has mentioned cosign

After inspecting the layers i think you should start thinking about signing your images: https://github.com/sigstore/cosign/
