The following examples demonstrate the capabilities of kubectl-slice.
Tekton Pipelines is a powerful tool that's available through a Helm Chart from the cd.foundation. We can grab it from their Helm repository and render it locally, then use kubectl-slice to split it into multiple files.
We'll use the following filename template so there's one folder for each Kubernetes resource kind, so all Secrets for example are in the same folder, then we will use the resource name as defined in metadata.name. We'll also modify the name, since some of the Tekton resources have an FQDN for a name, like tekton.pipelines.dev, with the dottodash template function:
We will render the Helm Chart locally to stdout with:
helm repo add cdf https://cdfoundation.github.io/tekton-helm-chart/
helm template tekton cdf/tekton-pipelineThen we can pipe that output directly to kubectl-slice:
helm template tekton cdf/tekton-pipeline | kubectl-slice --template '{{.kind|lower}}/{{.metadata.name|dottodash}}.yaml' --output-dir .Which will render the following output:
