Platform · 2 — Containers & data · ~6 min · Cloud — Kubernetes & Orchestration
What is this?
Kubernetes Secrets hold sensitive values — still base64, so encrypt etcd and restrict RBAC.
Why should you care?
CloudVerse prefers cloud secret stores synced into K8s or CSI drivers.
See it live — copy this example
Use AWS/Azure/GCP free tier or local Docker/Kind. Sketches and YAML are meant to be typed and adapted.
apiVersion: v1
kind: Secret
metadata: { name: api-db }
type: Opaque
stringData:
connectionString: "Server=...;Password=..."
# better long-term: ExternalSecrets → Vault/KeyVaultWhat happened?
- RBAC least privilege.
- Enable encryption at rest.
- Rotate.
- Avoid logging secret env values.
Practice next
- Create Secret.
- Mount into Pod.
- Verify not in git.
- Wire ExternalSecrets.
- Rotate password + restart.
Remember
Sensitive data. RBAC + encrypt. Prefer external store.
CloudVerse db Secret
Pod mounts connection string.
Outcome: No password in image or git.
