Formerly, software was built by composing libraries. Nowadays, in addition to that, complex applications are often built by glueing together microservices, including artefacts from different sources with varying care applied to the presentation of resulting 'apps'. HelmQA, which runs as a command-line tool or as a service, offers open source quality assurance by assessing the quality dimensions (completeness, consistency, accuracy, compliance) of declarative files such as Helm's Chart.yml, Helm templates and Kubernetes deployment descriptors. Run HelmQA in batch mode for occasional use, or in 'livecheck' mode for CI/CD integration with local Docker or hosted instance backends.
