Kubernetes Secrets Automation

Kubernetes Secrets Automation - 2025 Best Practices Implementation

Status: IMPLEMENTATION COMPLETE - Production-ready secrets automation
Security: ENTERPRISE-GRADE - Following 2025 industry best practices
Integration: CI/CD READY - Automated deployment pipeline compatible

Overview

Implemented comprehensive Kubernetes secrets automation for the VibeCode platform following 2025 best practices. The solution supports multiple deployment scenarios from local development to enterprise production with external secret management systems.

Implementation Status

Core Automation Completed

Automated Secret Creation: Real-time creation from environment variables
Helm Pre-Install Hooks: Automatic secret setup during deployment
CI/CD Integration Scripts: Production-ready automation scripts
External Secrets Operator: Enterprise-grade external secret management
Multi-Environment Support: Dev/staging/production configurations

Security Features Implemented

No Hardcoded Secrets: All secrets from environment variables or external systems
RBAC Integration: Proper role-based access control
Secret Rotation Support: Automated update mechanisms
Audit Logging: Complete secret access tracking
Environment Isolation: Namespace-based secret separation

Implementation Components

1. Automated Secret Creation Script (`scripts/setup-secrets.sh`)

2025 Best Practices Features:

Multi-Source Environment Loading: Automatic detection of .env.local, .env, or CI/CD variables
Comprehensive Validation: Pre-deployment secret validation and testing
Idempotent Operations: Safe to run multiple times without conflicts
Resource Verification: Automated post-deployment secret validation
Detailed Logging: Color-coded output with clear success/error reporting

Usage Examples:

# Local development
./scripts/setup-secrets.sh

# Production deployment
./scripts/setup-secrets.sh vibecode-prod

# Verification only
./scripts/setup-secrets.sh --verify-only

# CI/CD dry-run
./scripts/setup-secrets.sh --dry-run vibecode-staging

Supported Environment Variables:

DD_API_KEY - Datadog API key for monitoring
POSTGRES_PASSWORD - PostgreSQL admin password
DD_POSTGRES_PASSWORD - Datadog database user password (preferred; legacy DATADOG_POSTGRES_PASSWORD supported as fallback)

2. Helm Pre-Install Hooks (`charts/vibecode-platform/templates/datadog-secret-hook.yaml`)

2025 Best Practices Features:

Pre-Install Automation: Secrets created before application deployment
Security Context: Non-root execution with minimal privileges
Resource Limits: Proper CPU/memory constraints
Cleanup Automation: Automatic cleanup after successful execution
RBAC Compliance: Minimal required permissions

Kubernetes Resources Created:

# Job for secret creation
kind: Job
metadata:
  annotations:
    "helm.sh/hook": pre-install,pre-upgrade
    "helm.sh/hook-weight": "-5"
    "helm.sh/hook-delete-policy": before-hook-creation,hook-succeeded

# ServiceAccount with minimal permissions
kind: ServiceAccount
# Role with only secret management permissions
kind: Role
# RoleBinding for secure access
kind: RoleBinding

3. External Secrets Operator Configuration (`k8s/external-secrets/`)

Enterprise-Grade Features:

Multi-Provider Support: AWS Secrets Manager, HashiCorp Vault, Azure Key Vault
Automatic Rotation: Hourly refresh from external providers
Template-Based Secrets: Flexible secret structure management
Reloader Integration: Automatic pod restart on secret changes
Cluster-Wide Secrets: Support for shared secrets across namespaces

Supported External Providers:

AWS Secrets Manager with IAM role authentication
HashiCorp Vault with Kubernetes authentication
Azure Key Vault with Workload Identity
Google Secrets Manager with service account
Local Kubernetes secrets (for development/testing)

Technical Implementation Details

Helm Integration

Datadog Configuration Structure:

datadog:
  enabled: true
  targetSystem: "linux"

  datadog:
    apiKeyExistingSecret: datadog-secret  # References automated secret
    site: datadoghq.com

  agents:
    enabled: true  # DaemonSet (node agents)
    image:
      tag: "7.50.0"  # Version pinned for consistency

  clusterAgent:
    enabled: true  # Deployment (cluster agent)
    confd:
      postgres.yaml: |  # Database monitoring configuration
        cluster_check: true
        instances:
        - host: postgres-primary.vibecode-dev.svc.cluster.local
          username: datadog
          password: "PLACEHOLDER_PASSWORD"  # Set via automation
          dbm: true

Security Implementation

RBAC Configuration:

# Minimal permissions for secret management
rules:
- apiGroups: [""]
  resources: ["secrets"]
  verbs: ["get", "list", "create", "update", "patch", "delete"]

Security Context:

securityContext:
  runAsNonRoot: true
  runAsUser: 65534  # Nobody user
  allowPrivilegeEscalation: false
  readOnlyRootFilesystem: true
  capabilities:
    drop: ["ALL"]

Deployment Validation

Automated Testing Results

Script Validation:

All dependencies found (kubectl, helm)
Environment variables loaded from .env.local
Datadog API Key: VALID (32 characters)
PostgreSQL Password: VALID
Datadog PostgreSQL User Password: VALID
Connected to Kubernetes cluster: kind-vibecode-test
Namespace 'vibecode-dev' created
Secret 'datadog-secret' created successfully
Secret 'postgres-credentials' created successfully

Secret Verification:

kubectl get secrets -n vibecode-dev
NAME                  TYPE    DATA   AGE
datadog-secret        Opaque  1      34s
postgres-credentials  Opaque  2      34s

Content Validation:

# API key properly stored (32 characters)
kubectl get secret datadog-secret -n vibecode-dev -o jsonpath='{.data.api-key}' | base64 -d | wc -c
32

# Database credentials structure correct
kubectl get secret postgres-credentials -n vibecode-dev -o jsonpath='{.data}' | jq 'keys'
["datadog-password", "postgres-password"]

# 2. Setup secrets automatically
./scripts/setup-secrets.sh

# 3. Deploy with Helm
helm install vibecode-dev ./charts/vibecode-platform \
  -f ./charts/vibecode-platform/values-dev.yaml \
  --namespace=vibecode-dev

CI/CD Pipeline Integration

# GitHub Actions / GitLab CI example
steps:
  - name: Setup Kubernetes Secrets
    run: |
      export DD_API_KEY="${{ secrets.DATADOG_API_KEY }}"
      export POSTGRES_PASSWORD="${{ secrets.POSTGRES_PASSWORD }}"
      export DATADOG_POSTGRES_PASSWORD="${{ secrets.DATADOG_POSTGRES_PASSWORD }}"
      ./scripts/setup-secrets.sh ${{ env.ENVIRONMENT }}

  - name: Deploy with Helm
    run: |
      helm upgrade --install vibecode-${{ env.ENVIRONMENT }} \
        ./charts/vibecode-platform \
        -f ./charts/vibecode-platform/values-${{ env.ENVIRONMENT }}.yaml \
        --namespace=vibecode-${{ env.ENVIRONMENT }}

Enterprise External Secrets Workflow

# 1. Install External Secrets Operator
helm install external-secrets external-secrets/external-secrets \
  -n external-secrets-system --create-namespace

# 2. Configure provider (AWS/Vault/Azure)
kubectl apply -f k8s/external-secrets/external-secret-datadog.yaml

# 3. Deploy platform (secrets automatically synced)
helm install vibecode-prod ./charts/vibecode-platform \
  -f ./charts/vibecode-platform/values-prod.yaml
