Using pkg with scorecard

Checking OpenSSF score for a Go package.

1. Generate and export GITHUB_AUTH_TOKEN env var.

2. Verify scorecard is installed:

scorecard version
         __  ____     ____    ___    ____    _____    ____      _      ____    ____
        / / / ___|   / ___|  / _ \  |  _ \  | ____|  / ___|    / \    |  _ \  |  _ \
       / /  \___ \  | |     | | | | | |_) | |  _|   | |       / _ \   | |_) | | | | |
  _   / /    ___) | | |___  | |_| | |  _ <  | |___  | |___   / ___ \  |  _ <  | |_| |
 (_) /_/    |____/   \____|  \___/  |_| \_\ |_____|  \____| /_/   \_\ |_| \_\ |____/
./scorecard: OpenSSF Scorecard

GitVersion:    5.2.1
GitCommit:     ab2f6e92482462fe66246d9e32f642855a691dc1
GitTreeState:  clean

To check the score, we need to pass the Go package URL. But what if we have only the package name? This is where the pkg CLI comes in handy. pkg queries the pkg.go.dev service for information and returns package info in JSON format.

3. Send a query to pkg.go.dev:

pkg go.opentelemetry.io/otel | jq -r '.repository'

response:

github.com/open-telemetry/opentelemetry-go

4. Send a query to scorecard

scorecard --repo github.com/open-telemetry/opentelemetry-go --format json | jq .score

9.6
