# k8s-yaml-filter

### Installation

```sh

npm i -g k8s-yaml-filter

```

### usage

```sh

k8sf [-i type,type] [-o type,type]

```

Takes stdin, selects only objects in the 'in_filter', discards

objects in the 'out_filter', and writes the result to stdout.

The use case is with e.g. Kubernetes, you have a YAML file

which has CRD, webhook, and objects using these.

By default filter for kind

Apply the same YAML 3 times:

```sh

cat foo.yaml | k8sf -i CustomResourceDefinition | kubectl apply -f -

cat foo.yaml | k8sf -i ValidatingWebhookConfiguration | kubectl apply -f -

cat foo.yaml | kubectl apply -f -

```

on the last run you could choose

-o CustomResourceDefinition,ValidatingWebhookConfiguration

but its a bit moot since Kubernetes will properly apply the unchanged

CRD and WebHook

filter on other field:

```sh

cat foo.yaml | k8sf -i metadata/namespace=kong,metadata/name=kong | kubectl apply -f -

```
