rekor VS Lean and Mean Docker containers

There could be asset hashes in sigstore: https://sigstore.dev/

Is there a good way to run native mobile app GUI tests with GitHub Actions?

A VM/container emulator like anbox, waydroid, (or all of ChromeOS Flex in KVM) in a GitHub Action is probably enough to run GUI tests?

"Build your own SLSA 3+ provenance builder on GitHub Actions"

I expect something like https://sigstore.dev

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).

With containers being the heart of Cloud Native application development, it has become even more critical to ensure the integrity of the containers. One of the ways to do this to sign and verify the container images.sigstore is a open source project that empowers software developers to securely sign the container images.

https://sigstore.dev - although its really not true to say I built it. I started it off, but very quickly smarter folks then me jumped on board and really took it to all sorts of new directions.

Powered by Wolfi, Chainguard Images are a suite of distroless images that consolidate the base features of the Wolfi undistro into end-user container images that can be integrated into existing workflows. Chainguard Images are fully declarative and reproducible, and include SBOMs that cover all image dependencies. In addition, Chainguard Images are signed via Sigstore, which attests the provenance of all artifacts. All images and corresponding signatures, as well as their SBOMs, are hosted in Chainguard's OCI registry cgr.dev.

What's your thoughts on the sigstore project from the linux foundation?

And if you want to make the container quickly secure without bloats, maybe give this a try https://github.com/slimtoolkit/slim

Slim.ai presents the data in a more user friendly way than many of the other tools in this post. On top of its open source SlimToolkit for identifying the contents of an image, Slim.ai uses Trivy for vulnerability scanning.

What about https://github.com/slimtoolkit/slim?

A last practice that I do not use at all and which may interest you is to use slim toolkit to keep only the useful elements in your final image.

Anyone tried using https://github.com/docker-slim/docker-slim To minify an image?..

Distroless images are better left for people with serious need for lightweight images and good Linux knowledge because they require lot of planning with the build so that they stay light and work. If you need lighter images but docker isn't your main tool and you can't afford to take hours and hours of practicing different build strategies you can check docker-slim (https://dockersl.im/). With this tool you can easily size down the images.

Maybe this would help in that regard: https://github.com/docker-slim/docker-slim
