Progressive Delivery Operator for Kubernetes.
Flagger is a progressive delivery tool that automates the release process for applications running on Kubernetes. It reduces the risk of introducing a new software version in production by gradually shifting traffic to the new version while measuring metrics and running conformance tests.
check-break helps you to discover compatibility breaks between two git revisions of your code, and to improve decisions-making to determine if a new major version is required. In few words, if you follow semver (or try to stick to it), you must use check-break ;-)
check-break itself follows semver and monitors its own changes. For now, it's under heavy development, use it at your own risks, compatibility breaks could happen at every moment.
Spinnaker is an open source, multi-cloud continuous delivery platform for releasing software changes with high velocity and confidence.
