Image Build Attestation

All the image builds/pushes are attested for provenance and integrity using actions/attest-build-provenance. They can be verfied by downloading the recent bundle from the attestations page and having the latest version of GitHub CLI installed in your system. Then, execute the following command:

gh attestation verify oci://<insert-image-url> --owner kbdharun --bundle <path/to/attestation_file.sigstore.json>

Where, <insert-image-url> is the URL of the image you want to verify (don't specify a tag) and <path/to/attestation_file.sigstore.json> is the path to the downloaded attestation file.

Using as webtop

You can use these images as webtop by using the following these steps and replacing the image name with any image from this repository.
