Usage

Generate age key

age-keygen -o $HOME/.config/sops/age/keys.txt

Create .sops.yaml file in the repo root and copy the age public key

.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
metadata:
  name: gitea-secret-generator
  annotations:
    config.kubernetes.io/function: |
        exec:
          path: ksops        
files:
- ./secret.enc.yaml

Use secret generator in kustomization.yaml

generators:
  - ./secret-generator.yaml
