🌐 The Challenge

In Kubernetes, every namespace needs its own image pull secret to fetch private container images. Manually creating and updating these secrets across dozens of namespaces becomes:

• Tedious & Error-Prone: Copy-paste mistakes leave deployments broken.
• Time-Consuming: Running repetitive commands for each new namespace.
• Hard to Audit: Rotating credentials means hunting down every secret to update.

🛠️ Our Solution

Define a single ClustRegCred custom resource with your registry credentials and target namespaces. The operator then:

• Automatically creates (or updates) the named image pull secret in each listed namespace.
• Watches for changes—to keep all secrets in sync when you rotate credentials.

apiVersion: registry.example.com/v1
kind: ClustRegCred
metadata:
  name: sample-clustregcred
spec:
  registry: https://index.docker.io/v1/
  username: your-user
  password: your-pass
  secretName: my-image-pull-secret
  namespaces:
    - project-alpha
    - project-beta

🤝 Why It Matters

• Peace of Mind: One source of truth for your registry credentials.
• Zero Downtime: Instant rollout of rotated passwords—no manual steps.
• Audit-Friendly: All changes tracked in Git and Kubernetes events.

🚧 Next Steps & Ideas

Future enhancements and alternative “secret injection” patterns under consideration:

• Mutating Webhook Injection
• Sidecar / Init Container Pattern
• Namespace-Bound ServiceAccount Secrets
