While preparing Traefik container images for publication, we are reviewing third-party dependencies and their licenses for compliance using an SBOM-based scan.

During this review, we identified the Go dependency github.com/go-acme/tencentclouddnspod@v1.0.1208 included in the Traefik build. The dependency is referenced from the main Traefik application repository via go.mod

We are currently unable to clearly determine the license for this dependency, and would appreciate clarification from the community on the following:

  • What is the correct license for github.com/go-acme/tencentclouddnspod@v1.0.1208?

  • Is this dependency required by default for Traefik builds, or only for specific providers / features ?

  • Are there any references or documentation confirming the license or intended usage of this dependency?

SBOM / Dependency Details

  • Project: Traefik (main application repository)

  • Dependency: github.com/go-acme/tencentclouddnspod

  • Version: v1.0.1208

  • Package type: Go module / binary

  • Identified via: SBOM generation (Trivy)

This clarification is required for license verification prior to container image publishing.

Any guidance would be greatly appreciated.

Thanks!

This is the community forum (users supporting users) of Traefik, source at https://github.com/traefik. For go-acme with source at https://github.com/go-acme, you should probably ask in their forum or create an issue in their Github.

Thanks for the clarification.

We noticed that the dependency github.com/go-acme/tencentclouddnspod@v1.0.1208 is pulled in via Traefik’s go.mod:
https://github.com/traefik/traefik/blob/94eba471f19034627e94bdea3e2dd79d24de1af1/go.mod#L210

We attempted to follow up with the upstream project, but the go-acme repository does not have GitHub Issues enabled, so we’re unable to raise a license clarification request there.

Could you please advise on the recommended way to obtain or confirm the license information for this dependency?
