Verify a container image signature

Docker container images are now signed using cosign with signatures published to a Github Container registry with insomnia-mockbin repository.

Steps to verify signatures for signed Kong Insomnia Mockbin Docker container images in two different ways:

A minimal example, used to verify an image without leveraging any annotations. For the minimal example, you only need Docker details, a GitHub repo name, and a GitHub workflow filename.

cosign verify \
  ghcr.io/kong/insomnia-mockbin:<tag>@sha256:<digest> \
  --certificate-oidc-issuer='https://token.actions.githubusercontent.com' \
  --certificate-identity-regexp='https://github.com/Kong/insomnia-mockbin/.github/workflows/release.yaml'

A complete example, leveraging optional annotations for increased trust. For the complete example, you need the same details as the minimal example, as well as any of the optional annotations you wish to verify:

cosign verify \
  ghcr.io/kong/insomnia-mockbin:<tag>@sha256:<digest> \
  --certificate-oidc-issuer='https://token.actions.githubusercontent.com' \
  --certificate-identity-regexp='https://github.com/Kong/insomnia-mockbin/.github/workflows/release.yaml' \
  -a repo='Kong/insomnia-mockbin' \
  -a workflow='Package & Release'

Verify a container image provenance

Kong Insomnia Mockbin produces build provenance for docker container images for Github tags, which can be verified using cosign / slsa-verifier with attestations published to a Github Container registry with insomnia-mockbin repository.

Steps to verify provenance for signed Kong Insomnia Mockbin Docker container images:

Fetch the image <manifest_digest> using regctl:

regctl image digest ghcr.io/kong/insomnia-mockbin:<tag>

A minimal example, used to verify an image without leveraging any annotations. For the minimal example, you only need Docker Image manifest, a GitHub repo name.

cosign verify-attestation \
  ghcr.io/kong/insomnia-mockbin:<tag>@sha256:<manifest_digest> \
  --type='slsaprovenance' \
  --certificate-oidc-issuer='https://token.actions.githubusercontent.com' \
  --certificate-identity-regexp='^https://github.com/slsa-framework/slsa-github-generator/.github/workflows/generator_container_slsa3.yml@refs/tags/v[0-9]+.[0-9]+.[0-9]+$'
