Deployment platforms

Hi , is there any tutorial on deployment platforms like mariner, janus, donki ? at our company we have a deployment platform named Mariner and it has follwing components:
Norfolk - unit test, build, and publish
coastgaurd - policy engine
spinnaker - continuous delivery platform
kubernetes - orchestration system

not sure if deployment platforms are industry standtard tools or custom made. would someone please clarify me on this

Out of that list KodeKloud only have Kubernetes courses.
