**Create key and Import to kubernetes:**
**Example using sops decryption:**
```yaml
apiVersion: kustomize.toolkit.fluxcd.io/v1
kind: Kustomization
metadata:
name: sample-sync
spec:
interval: 1m
sourceRef:
kind: GitRepository
name: git-repo-name
path: deploy/sample-app
prune: true
decryption:
provider: sops
secretRef:
name: flux-sops-age
```
**Importing sops private key:**
Using kustomization used by operator to deploy base fluxcd manifests for deployments and reconciliation.
``` bash
NAMESPACE=ns-name
AGE_FILE=deploy/flux/.env.d/age.agekey
SECRET_NAME=flux-sops-age
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
namespace: your-namespace
resources:
- sample-app.yaml
secretGenerator:
- name: flux-sops-age
files:
- "age.agekey=./.env.d/age.agekey" #change to private key file path
generatorOptions:
disableNameSuffixHash: true
```
# creates age key
age-keygen -o ${AGE_FILE}
# imports to an namespace
cat ${AGE_FILE} |
**Import using kubectl:**
```bash
SECRET_NAME="flux-sops-age"
NAMESPACE="your-namespace"
kubectl create secret generic ${SECRET_NAME} \
--namespace=${NAMESPACE} \
--from-file=age.agekey=/dev/stdin
--from-file=age.agekey=/dev/stdin #change to private key file path
