## Usage
|
|
|
|
Generate age key
|
|
|
|
```bash
|
|
mkdir -p $HOME/.config/sops/age
|
|
age-keygen -o $HOME/.config/sops/age/keys.txt
|
|
```
|
|
|
|
Create `.sops.yaml` file in the repo root and copy the age public key
|
|
|
|
`.sops.yaml`
|
|
```yaml
|
|
creation_rules:
|
|
- unencrypted_regex: "^(apiVersion|metadata|kind|type)$"
|
|
age: "<age public key>"
|
|
```
|
|
|
|
Create `secret.yaml`
|
|
|
|
```yaml
|
|
apiVersion: v1
|
|
kind: Secret
|
|
metadata:
|
|
name: mysecret
|
|
type: Opaque
|
|
data:
|
|
username: YWRtaW4=
|
|
password: MWYyZDFlMmU2N2Rm
|
|
```
|
|
|
|
Encrypt the secret using sops
|
|
|
|
```bash
|
|
sops -e secret.yaml > secret.enc.yaml
|
|
```
|
|
|
|
Create `secret-generator.yaml`
|
|
|
|
```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`
|
|
|
|
```yaml
|
|
generators:
|
|
- ./secret-generator.yaml
|
|
```
|
|
|
|
Deploy application
