kustomize
kustomize is a command line tool supporting
template-free customization of YAML (or JSON)
objects that conform to the kubernetes style.
If your objects have a kind and a metadata field,
kustomize can patch them to help you manage
configuration sharing and re-use.
For more details, try a demo.
Installation
This assumes Go (v1.10.1 or higher)
is installed and your PATH contains $GOPATH/bin:
go get k8s.io/kubectl/cmd/kustomize
Usage
1) Make a base
A base configuration is a kustomization file listing a set of k8s resources - deployments, services, configmaps, secrets that serve some common purpose.
2) Customize it with overlays
An overlay customizes your base along different dimensions for different purposes or different teams, e.g. for development, staging and production.
3) Run kustomize
Run kustomize on your overlay. The result
is printed to stdout as a set of complete
resources, ready to be applied to a cluster.
