 Each entry in the argument list results in the creation of one Secret resource (it's a generator of N secrets).
 
 This works like the [configMapGenerator](/docs/reference/api/kustomization-file/configmapgenerator).
-
-```yaml
-apiVersion: kustomize.config.k8s.io/v1beta1
-kind: Kustomization
-
-secretGenerator:
-- name: app-tls
-  files:
-  - secret/tls.crt
-  - secret/tls.key
-  type: "kubernetes.io/tls"
-- name: app-tls-namespaced
-  # you can define a namespace to generate
-  # a secret in, defaults to: "default"
-  namespace: apps
-  files:
-  - tls.crt=catsecret/tls.crt
-  - tls.key=secret/tls.key
-  type: "kubernetes.io/tls"
-- name: env_file_secret
-  envs:
-  - env.txt
-  type: Opaque
-- name: secret-with-annotation
-  files:
-  - app-config.yaml
-  type: Opaque
-  options:
-    annotations:
-      app_config: "true"
-    labels:
-      app.kubernetes.io/name: "app2"
-```

-Secret Resources may be generated much like ConfigMaps can. This includes generating them
-from literals, files or environment files.

-Secret type is set using the `type` field.

-## Example
-
-### File Input
-
-```yaml
-# kustomization.yaml
-apiVersion: kustomize.config.k8s.io/v1beta1
-kind: Kustomization
-secretGenerator:
-- name: app-tls
-  files:
-    - "tls.crt"
-    - "tls.key"
-  type: "kubernetes.io/tls"
-```
-
-```yaml
-# tls.crt
-LS0tLS1CRUd...tCg==
-```
-
-```yaml
-# tls.key
-LS0tLS1CRUd...0tLQo=
-```
-
-### Build Output
-
-```yaml
-apiVersion: v1
-data:
-  tls.crt: TFMwdExTMUNSVWQuLi50Q2c9PQ==
-  tls.key: TFMwdExTMUNSVWQuLi4wdExRbz0=
-kind: Secret
-metadata:
-  name: app-tls-c888dfbhf8
-type: kubernetes.io/tls
