Secrets Management

When to Use

• Storing application credentials securely
• Configuring CI/CD authentication
• Implementing secrets rotation
• Setting up GitOps-compatible secret management

Solution Decision Matrix

Scenario	Recommended Solution
Single cloud, simple apps	Cloud-native (AWS Secrets Manager, Azure Key Vault, GCP Secret Manager)
Multi-cloud / hybrid	HashiCorp Vault
GitOps with Kubernetes	Sealed Secrets or External Secrets Operator
Local dev / small teams	SOPS with age/GPG
CI/CD → Cloud	OIDC federation (no long-lived keys)

Cloud-Native Detection

Check which cloud provider the project uses:

• *.tf with provider "aws" → AWS Secrets Manager
• *.tf with provider "azurerm" → Azure Key Vault
• *.tf with provider "google" → GCP Secret Manager

Use the context7 MCP server or a cloud documentation MCP server to look up provider-specific syntax.

Kubernetes Secrets Detection

Check for existing patterns:

• SealedSecret resources → Bitnami Sealed Secrets
• ExternalSecret resources → External Secrets Operator
• *.enc.yaml files → SOPS encryption
• vault-agent sidecars → HashiCorp Vault

CI/CD Credentials Decision

CI Platform	Cloud	Approach
GitHub Actions	AWS	OIDC with aws-actions/configure-aws-credentials
GitHub Actions	Azure	OIDC with azure/login
GitHub Actions	GCP	OIDC with google-github-actions/auth
GitLab CI	AWS/GCP	OIDC with CI_JOB_JWT
Bitbucket	AWS	Repository variables + assume role
Any	Any	HashiCorp Vault with JWT/OIDC auth

Rule: Always prefer OIDC federation over long-lived access keys.

Process

1. Discover context → Check existing secret patterns in codebase
2. Choose solution → Use decision matrix based on scenario
3. Look up implementation → Use the context7 MCP server or a cloud documentation MCP server for current syntax
4. Implement rotation → Set rotation policy (30-90 days for credentials)
5. Enable auditing → Configure access logging on secret store
6. Document break-glass → Define emergency access procedure

Security Checklist

• No secrets in code, environment variables visible in UI, or logs
• Rotation policy defined (30-90 days for credentials)
• Least privilege access to secret stores
• Audit logging enabled on all secret access
• OIDC used for CI/CD (no long-lived access keys)
• Secrets encrypted at rest and in transit
• Break-glass procedure documented
• Secret scanning enabled in CI (gitleaks, trufflehog)

Anti-Patterns

❌ Don't	✅ Do
Hardcode secrets in code	Use secret references
Commit .env files	Use .env.example with placeholders
Share secrets via Slack/email	Use secret manager with access control
Same secret across environments	Separate secrets per environment
Long-lived CI/CD credentials	OIDC federation with short-lived tokens
Secrets in ConfigMaps	Use Kubernetes Secrets (encrypted at rest)
