### Mirror to All Namespaces
|
||||
|
||||
Use the `all` keyword to mirror to every namespace in the cluster (except the source):
|
||||
|
||||
**Source Resource:**
|
||||
```yaml
|
||||
apiVersion: v1
|
||||
kind: ConfigMap
|
||||
metadata:
|
||||
name: global-config
|
||||
namespace: default
|
||||
labels:
|
||||
kubemirror.raczylo.com/enabled: "true"
|
||||
annotations:
|
||||
kubemirror.raczylo.com/sync: "true"
|
||||
kubemirror.raczylo.com/target-namespaces: "all"
|
||||
data:
|
||||
cluster_name: "production"
|
||||
region: "us-west-2"
|
||||
```
|
||||
|
||||
> **⚠️ Use with caution:** The `all` keyword mirrors to ALL namespaces (including kube-system, kube-public, etc.) except the source namespace. Consider using `all-labeled` for safer opt-in behavior.
|
||||
|
||||
### Mirror to All Labeled Namespaces
|
||||
|
||||
Use `all-labeled` for opt-in mirroring where target namespaces must explicitly allow mirrors:
|
||||
|
||||
**Source Resource:**

### Using with ExternalSecrets Operator
|
||||
|
||||
KubeMirror works seamlessly with the [ExternalSecrets Operator](https://external-secrets.io/) to distribute secrets from external stores (like 1Password, Vault, AWS Secrets Manager) across multiple namespaces.
|
||||
|
||||
**Example - Distribute Docker Registry Credentials from 1Password:**
|
||||
|
||||
```yaml
|
||||
apiVersion: external-secrets.io/v1
|
||||
kind: ExternalSecret
|
||||
metadata:
|
||||
name: 1p-docker-config
|
||||
namespace: default
|
||||
spec:
|
||||
# Pull secrets from 1Password/Vault/etc
|
||||
secretStoreRef:
|
||||
kind: ClusterSecretStore
|
||||
name: 1password-homecluster
|
||||
|
||||
target:
|
||||
creationPolicy: Owner # Standard ExternalSecrets setting - KubeMirror strips ownerReferences from mirrors
|
||||
deletionPolicy: Retain
|
||||
name: multi-registry-secret
|
||||
|
||||
# Include KubeMirror annotations in the secret template
|
||||
template:
|
||||
metadata:
|
||||
labels:
|
||||
kubemirror.raczylo.com/enabled: "true"
|
||||
annotations:
|
||||
kubemirror.raczylo.com/sync: "true"
|
||||
kubemirror.raczylo.com/target-namespaces: "all" # or specific namespaces

|

{
|
||||
"auths": {
|
||||
"ghcr.io": {
|
||||
"username": "{{ .ghcrUsername | toString }}",
|
||||
"auth": "{{ printf "%s:%s" .ghcrUsername .ghcrPassword | b64enc }}"
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
data:
|
||||
- remoteRef:
|
||||
key: DockerAuth/ghcrio_username
|
||||
secretKey: ghcrUsername
|
||||
- remoteRef:
|
||||
key: DockerAuth/ghcrio_password
|
||||
secretKey: ghcrPassword
|
||||
|
||||
refreshInterval: 24h
|
||||
```
|
||||
|
||||
**How it Works:**
|
||||
|
||||
1. **ExternalSecrets creates the source secret** with KubeMirror labels/annotations (source can be owned by any controller)
|
||||
2. **KubeMirror detects the source** via the `kubemirror.raczylo.com/enabled` label
|
||||
3. **KubeMirror creates mirrors** in target namespaces with:
|
||||
- Labels identifying them as KubeMirror-managed mirrors
|
||||
- Annotations linking back to the source (namespace, name, UID, content hash)
|
||||
- **No ownerReferences** - preventing conflicts with source controllers
|
||||
4. **ExternalSecrets refreshes the source** every 24h, updating only the source secret
|
||||
5. **KubeMirror detects content changes** via hash comparison and updates all mirrors
|
||||
6. Each controller manages its own resources independently - no conflicts
|
||||
|
||||
**Verification:**
|
||||
|
||||
```bash
|
||||
# Check source secret was created by ExternalSecrets
|
||||
kubectl get secret multi-registry-secret -n default -o jsonpath='{.metadata.annotations}'
|
||||
|
||||
# Verify mirrors were created by KubeMirror
|
||||
kubectl get secrets --all-namespaces -l kubemirror.raczylo.com/mirror=true
|
||||
|
||||
# Check sync status on source
|
||||
kubectl get secret multi-registry-secret -n default -o jsonpath='{.metadata.annotations.kubemirror\.raczylo\.com/sync-status}'
|
||||
```
|
||||
|
||||
See [examples/externalsecret-dockerconfig.yaml](examples/externalsecret-dockerconfig.yaml) for a complete working example.
|
||||
|
||||
### Transformation Rules
|
||||
|
||||
KubeMirror supports powerful transformation rules that modify resources during mirroring. This enables environment-specific configurations, security hardening, and dynamic value generation.

## ExternalSecrets Integration
|
||||
|
||||
KubeMirror integrates seamlessly with the [ExternalSecrets Operator](https://external-secrets.io/) to distribute secrets from external stores (1Password, Vault, AWS Secrets Manager, etc.) across multiple namespaces.
|
||||
|
||||
### Overview
|
||||
|
||||
The `externalsecret-dockerconfig.yaml` example demonstrates how to:
|
||||
1. Sync secrets from 1Password/Vault/etc using ExternalSecrets
|
||||
2. Mirror those secrets to multiple namespaces using KubeMirror
|
||||
3. Avoid race conditions between the two controllers
|
||||
|
||||
### Prerequisites
|
||||
|
||||
```bash
|
||||
# Install ExternalSecrets Operator
|
||||
helm repo add external-secrets https://charts.external-secrets.io
|
||||
helm install external-secrets external-secrets/external-secrets -n external-secrets-system --create-namespace
|
||||
|
||||
# Configure your ClusterSecretStore (example for 1Password)
|
||||
kubectl apply -f your-clustersecretstore.yaml
|
||||
```
|
||||
|
||||
### Quick Start
|
||||
|
||||
```bash
|
||||
# Apply the ExternalSecret example
|
||||
kubectl apply -f examples/externalsecret-dockerconfig.yaml
|
||||
|
||||
# Verify the source secret was created
|
||||
kubectl get secret multi-registry-secret -n default
|
||||
|
||||
# Verify mirrors were created by KubeMirror
|
||||
kubectl get secrets --all-namespaces -l kubemirror.raczylo.com/mirror=true
|
||||
|
||||
# Check sync status
|
||||
kubectl get secret multi-registry-secret -n default \
|
||||
-o jsonpath='{.metadata.annotations.kubemirror\.raczylo\.com/sync-status}'
|
||||
```
|
||||
|
||||
### Key Configuration
|
||||
|
||||
**Ownership Model**
|
||||
|
||||
KubeMirror uses **labels and annotations** to manage mirrors, not ownerReferences. This allows it to work with sources managed by any controller (ExternalSecrets, ArgoCD, etc.):
|
||||
|
||||
```yaml
|
||||
target:
|
||||
creationPolicy: Owner # Source can be owned by ExternalSecrets
|
||||
name: multi-registry-secret
|
||||
template:
|
||||
metadata:
|
||||
labels:
|
||||
kubemirror.raczylo.com/enabled: "true" # KubeMirror detection
|
||||
annotations:
|
||||
kubemirror.raczylo.com/sync: "true"
|
||||
kubemirror.raczylo.com/target-namespaces: "all"
|
||||
```
|
||||
|
||||
**Separation of Concerns:**
|
||||
|
||||
- **Source Secret**: Owned by ExternalSecrets (or any other controller) via `ownerReferences`
|
||||
- **Mirror Secrets**: Managed by KubeMirror via labels + annotations (no ownerReferences copied)
|
||||
- **Relationship**: Mirrors link to source via annotations (`source-namespace`, `source-name`, `source-uid`)
|
||||
- **Result**: Each controller manages its own resources independently
|
||||
|
||||
### Examples in externalsecret-dockerconfig.yaml
|
||||
|
||||
The example file contains three complete examples:
|
||||
|
||||
1. **Docker Registry Credentials** - Mirrors Docker config to all namespaces using `target-namespaces: "all"`
|
||||
2. **Database Credentials** - Uses `all-labeled` for opt-in mirroring with namespace labels
|
||||
3. **Namespace with Opt-In Label** - Shows how to label namespaces to receive mirrors
|
||||
|
||||
### Verification
|
||||
|
||||
```bash
|
||||
# Check ExternalSecret status
|
||||
kubectl get externalsecret 1p-docker-config -n default
|
||||
|
||||
# View the created secret
|
||||
kubectl get secret multi-registry-secret -n default -o yaml
|
||||
|
||||
# Verify KubeMirror picked it up
|
||||
kubectl logs -n kubemirror-system -l app.kubernetes.io/name=kubemirror | grep multi-registry-secret
|
||||
|
||||
# Count how many namespaces received the mirror
|
||||
kubectl get secrets --all-namespaces -l kubemirror.raczylo.com/mirror=true \
|
||||
--field-selector metadata.name=multi-registry-secret | wc -l
|
||||
|
||||
# Check a specific mirror
|
||||
kubectl get secret multi-registry-secret -n production-app -o yaml
|
||||
```
|
||||
|
||||
### Testing Updates
|
||||
|
||||
Test that ExternalSecrets refreshes propagate to all mirrors:
|
||||
|
||||
```bash
|
||||
# Force ExternalSecret refresh
|
||||
kubectl annotate externalsecret 1p-docker-config -n default \
|
||||
force-sync="$(date +%s)" --overwrite
|
||||
|
||||
# Wait for ExternalSecret to sync (check status)
|
||||
kubectl get externalsecret 1p-docker-config -n default -w
|
||||
|
||||
# Verify mirrors are updated (check generation or content hash)
|
||||
kubectl get secret multi-registry-secret -n production-app \
|
||||
-o jsonpath='{.metadata.annotations.kubemirror\.raczylo\.com/source-content-hash}'
|
||||
```
|
||||
|
||||
### Common Issues
|
||||
|
||||
1. **Mirrors Not Created**
|
||||
- Verify the secret has `kubemirror.raczylo.com/enabled: "true"` label
|
||||
- Check that KubeMirror annotations are in the ExternalSecret template
|
||||
- View controller logs: `kubectl logs -n kubemirror-system -l app.kubernetes.io/name=kubemirror`
|
||||
|
||||
2. **ExternalSecret Not Syncing**
|
||||
- Check ExternalSecret status: `kubectl describe externalsecret <name> -n <namespace>`
|
||||
- Verify ClusterSecretStore is configured: `kubectl get clustersecretstore`
|
||||
- Check external-secrets-operator logs
|
||||
|
||||
### Alternative Backends
|
||||
|
||||
The example includes commented configurations for:
|
||||
- AWS Secrets Manager
|
||||
- HashiCorp Vault
|
||||
- Google Secret Manager
|
||||
|
||||
Uncomment and configure the ClusterSecretStore for your backend.
|
||||
|
||||
## Transformation Rules
|
||||
|
||||
KubeMirror supports transformation rules that modify resources during mirroring. This enables environment-specific configurations, security hardening, and dynamic value generation.
