Scribe integration

1. Obtain a Scribe Hub API Token

Sign in to Scribe Hub. If you don't have an account you can sign up for free here.
Create an API token in Scribe Hub > Settings > Tokens. Copy it to a safe temporary notepad until you complete the integration.

Important

The token is a secret and will not be accessible from the UI after you finalize the token generation.

2. Add the API token to the Bitbucket secrets

Add the Scribe Hub API token as SCRIBE_TOKEN by following the Bitbucket instructions.

3. Install Scribe CLI

Valint - Scribe CLI is required to generate evidence such as SBOMs and SLSA provenance. Install the Valint-pipe.

4. Instrument your build scripts

Alternative evidence stores

You can learn more about alternative stores here.

Details

OCI Evidence store

Valint supports both storage and verification flows for attestations and statement objects utilizing OCI registry as an evidence store.

Using OCI registry as an evidence store allows you to upload, download and verify evidence across your supply chain in a seamless manner.

Related flags:

OCI Enable OCI store.
OCI_REPO - Evidence store location.

Before you begin

Evidence can be stored in any accusable registry.

Write access is required for upload (generate).
Read access is required for download (verify).

You must first login with the required access privileges to your registry before calling Valint. For example, using docker login command.

Usage

  default:
    - step:
        name: scribe-bitbucket-oci-pipeline
