k8s-yaml-extract, is a powerful command-line interface (CLI) tool built for extraction of Kubernetes YAML manifests. This tool streamlines the process of filtering YAML files based on specified criteria, offering enhanced flexibility and control.
Flags:
--name: Extract YAMLs matching a specific resource name. ( REQUIRED )--kind: Extract YAMLs based on a particular Kubernetes resource kind.
Combined Filtering: Use both --name and --kind flags simultaneously for even more granular extraction.
It can work just by piping in from STDIN:
kustomize build example/ | k8s-yaml-extract --kind=deployment
kustomize build example/ | k8s-yaml-extract --name=my-app --kind=deployment
or a static existing file as a parameter:
k8s-yaml-extract --name=my-app --kind=deployment example/out.yaml
In order to use the k8s-yaml-extract command-line tool, you need to have Go (version 1.21) installed on your system.
