# This e2e test performs the following via a GitHub Actions schedule event. | |
# - Build the Go application into a Docker image | |
# - Push the image to ghcr.io | |
# - Generate SLSA provenance for the image | |
# - Upload the provenance to ghcr.io | |
# - Verify the created provenance attestation. | |
