Custom resources can be accessed from Golang using a number of clients. We will concentrate on: Using the client-go dynamic client (see “Dynamic Client”) Using a typed client: As provided by kubernetes-sigs/controller-runtime and used by the Operator SDK and Kubebuilder (see “controller...
Faster development and reduced errors as a result of automatic synchronization i.e., less manual code and seldom bugs creeping in. Cost saving Reusing of code components fasten the development process while reducing to write everything from scratch. Save tons to invest elsewhere. ...
