Alpine Linux Package Manager (apk) in Image

No violationsstackroxlowbuilddeploy

Alert on deployments with the Alpine Linux package manager (apk) present

Rationale: Package managers make it easier for attackers to use compromised containers, since they can easily add software.
Remediation: Run `apk --purge del apk-tools` in the image build for production containers.
