Using industry-standard tools based on PKI, GnuPG, and well-respected package managers, Helm can generate and verify signature files. a) Overview   -  I ntegrity is established by comparing a chart to a provenance record. Provenance records are stored in   provenance files , which are stored alongside a packaged chart. For example, if a chart is named   myapp-1.2.3.tgz , its provenance file will be   myapp-1.2.3.tgz.prov .  -  Provenance files are generated at packaging time ( helm package --sign ... ), and can be checked by multiple commands, notable   helm install --verify . b) The workflow This section describes a potential workflow for using provenance data effectively. Prerequisites: A valid PGP keyp...
