Container Documentation for Stunnel

Enterprise-grade Stunnel container for secure SSL/TLS tunneling and encryption. Provides robust encryption capabilities for network services, enabling secure communication between clients and servers. Features FIPS compliance options, security hardening, and optimized performance for enterprise deployments.

📌 Base Foundation: Security-hardened, minimal base OS designed for enterprise containerized environments from Cleanstart Registry.

Key Features Core capabilities and strengths of this container

• SSL/TLS encryption for network services
• FIPS 140-2 compliant encryption (when enabled)
• Support for multiple SSL/TLS versions
• Client and server certificate authentication

Common Use Cases Typical scenarios where this container excels

• Secure legacy applications without native SSL/TLS
• Create encrypted tunnels between network services
• Add SSL/TLS support to non-SSL aware services
• Implement secure client-server communication

Environment Variables Configuration options available through environment variables

Security Best Practices Recommended security configurations and practices

• Use FIPS mode in regulated environments
• Implement proper certificate management
• Configure minimum required TLS version
• Enable client certificate verification when needed
• Use read-only filesystem mounts
• Run as non-root user
• Regular security updates and patches
• Implement proper logging and monitoring

Kubernetes Security Context Recommended security context for Kubernetes deployments

yaml
securityContext:
  runAsNonRoot: true
  runAsUser: 1000
  runAsGroup: 1000
  readOnlyRootFilesystem: true
  allowPrivilegeEscalation: false
  capabilities:
    drop: ["ALL"]
    add: ["NET_BIND_SERVICE"]
