docker-cli-fips

All Chainguard Images contain verifiable signatures and high-quality SBOMs (software bill of materials), features that enable users to confirm the origin of each image build and have a detailed list of everything that is packed within.

You'll need cosign and jq in order to download and verify image attestations.

Registry and Tags for docker-cli-fips Image

Attestations are provided per image build, so you'll need to specify the correct tag and registry when pulling attestations from an image with cosign.

• cgr.dev/chainguard - the Public Registry contains our Developer Images, which typically comprise the latest* versions of an image.
• cgr.dev/<your-org-name> - contains all Production Images that your organisation has access to.

The commands listed on this page will default to the latest tag, but you can specify a different tag to fetch attestations for.

Verifying docker-cli-fips Image Signatures

The docker-cli-fips Chainguard Images are signed using Sigstore, and you can check the included signatures using cosign.

The cosign verify command will pull detailed information about all signatures found for the provided image.

Developer Images

cosign verify \
  --certificate-oidc-issuer=https://token.actions.githubusercontent.com \
  --certificate-identity=https://github.com/chainguard-images/images/.github/workflows/release.yaml@refs/heads/main \
  cgr.dev/chainguard/docker-cli-fips | jq

Production Images

cosign verify \
--certificate-oidc-issuer=https://token.actions.githubusercontent.com \
--certificate-identity=https://github.com/chainguard-images/images-private/.github/workflows/release.yaml@refs/heads/main \
cgr.dev/<your-org-name>/docker-cli-fips | jq

Downloading docker-cli-fips Image Attestations

The following attestations for the docker-cli-fips image can be obtained and verified via cosign:

To download an attestation, use the cosign download attestation command and provide both the predicate type and the build platform. For example, the following command will obtain the SBOM for the docker-cli-fips image on linux/amd64:

Developer Images

cosign download attestation \
  --platform=linux/amd64 \
  --predicate-type=https://spdx.dev/Document \
  cgr.dev/chainguard/docker-cli-fips | jq -r .payload | base64 -d | jq .predicate

Production Images

cosign download attestation \
--platform=linux/amd64 \
--predicate-type=https://spdx.dev/Document \
cgr.dev/<your-org-name>/docker-cli-fips | jq -r .payload | base64 -d | jq .predicate

By default, this command will fetch the SBOM assigned to the latest tag. You can also specify the tag you want to fetch the attestation from.

To download a different attestation, replace the --predicate-type parameter value with the desired attestation URL identifier.

Verifying docker-cli-fips Image Attestations

You can use the cosign verify-attestation command to check the signatures of the docker-cli-fips image attestations:

Developer Images

cosign verify-attestation \
  --type https://spdx.dev/Document \
  --certificate-oidc-issuer=https://token.actions.githubusercontent.com \
  --certificate-identity=https://github.com/chainguard-images/images/.github/workflows/release.yaml@refs/heads/main \
  cgr.dev/chainguard/docker-cli-fips

Production Images

cosign verify-attestation \
--type https://spdx.dev/Document \
--certificate-oidc-issuer=https://token.actions.githubusercontent.com \
--certificate-identity=https://github.com/chainguard-images/images-private/.github/workflows/release.yaml@refs/heads/main \
cgr.dev/<your-org-name>/docker-cli-fips

This will pull in the signature for the attestation specified by the --type parameter, which in this case is the SPDX attestation. You will receive output that verifies the SBOM attestation signature in cosign's transparency log:

Verification for cgr.dev/chainguard/docker-cli-fips --
The following checks were performed on each of these signatures:
- The cosign claims were validated
- Existence of the claims in the transparency log was verified offline
- The code-signing certificate was verified using trusted certificate authority certificates
