.sops.yaml

creation_rules:
  - unencrypted_regex: "^(apiVersion|metadata|kind|type)$"
    age: "<age public key>"

Create secret.yaml

apiVersion: v1
kind: Secret
metadata:
  name: mysecret
type: Opaque
data:
  username: YWRtaW4=
  password: MWYyZDFlMmU2N2Rm

Encrypt the secret using sops

sops -e secret.yaml > secret.enc.yaml

Create secret-generator.yaml

apiVersion: viaduct.ai/v1
kind: ksops

    config.kubernetes.io/function: |
        exec:
