Sign Your Container Images With Cosign Github Actions And Github

Sign Your Container Images With Cosign Github Actions And Github The github release assets for cosign contain sigstore bundle files produced by goreleaser while signing the cosign blob that is used to verify the integrity of the release binaries. Sign a container image with cosign and github actions alright, now that we have our keys set up, let’s see how we can sign our images from within a github actions workflow.

Sign Your Container Images With Cosign Github Actions And Github Cosign is a free open source project that provides keyless signatures for container images. it enables users to sign container images without requiring access to any keys or certificates. this guide will walk you through the steps to use cosign keyless signatures with github actions. Learn to sign, verify, and secure docker images in ci cd using cosign and github actions. practical, production grade walkthrough. First we will look at how to setup a github workflow using github actions to build multi architecture container images with buildah and push them to a registry with podman. then we will sign those images with cosign (sigstore) and detail what is needed to configure signature validation on the host. In this post, we’ll explore how to sign container images using cosign from the sigstore project and verify them using github’s oidc token. cosign is a tool designed to make signatures an invisible part of the infrastructure.

That’s all you have to do to sign your container image in github actions and store it in github packages (or any of the other container registries cosign supports as well). Learn how to sign and verify container images with cosign to establish trust in your software supply chain and prevent unauthorized image deployment. There is some boilerplate in this file common to github actions, but the high level overview of this is that we need to enable oidc, install cosign, build and push the container image, and then sign the container image. In this tutorial, we will take a brief look at supply chain attacks and security, plus how these can partially be mitigated by automatically signing container images using cosign and github actions.
