Skaffold is a command line tool that facilitates continuous development for Kubernetes applications. You can iterate on your application source code locally then deploy to local or remote Kubernetes clusters.
Skaffold handles the workflow for building, pushing and deploying your application. It also provides building blocks and describe customizations for a CI/CD pipeline.
see Skaffold’s README and website
kustomize lets you customize raw, template-free YAML files for multiple purposes, leaving the original YAML untouched and usable as is.
kustomize targets kubernetes; it understands and can patch kubernetes style API objects. It’s like make, in that what it does is declared in a file, and it’s like sed, in that it emits editted text.
