Context
The project requires robust identity management integration for OpenShift clusters. This includes handling DNS entries, authentication, and directory services through FreeIPA integration. The solution needs to support both development and production environments while maintaining security and scalability.
Considered Options
- Manual DNS and identity management
- Active Directory integration
- Custom LDAP implementation
- FreeIPA with automated integration
- Cloud-based identity providers
Decision
We have implemented a FreeIPA-based identity management solution with automated integration:
- IPA Server Integration
- Automated IPA entry management
- DNS integration
- Certificate management
- User and group synchronization
- Automation Components
- IPA helper playbooks (
ipaserver-helpers/
) - DNS entry management
- Automated record creation
- Certificate lifecycle management
- IPA helper playbooks (
- Security Features
- Secure authentication methods
- Certificate-based security
- Role-based access control
- Audit logging
- Integration Points
- DNS management
- User authentication
- Service accounts
- Certificate authorities
Rationale
- FreeIPA provides integrated identity, policy, and audit features
- Ansible automation ensures consistent configuration
- Built-in DNS management simplifies network integration
- Open-source solution with enterprise support options
- Strong security features and certificate management
Consequences
Positive
- Centralized identity management
- Automated DNS management
- Integrated certificate authority
- Consistent user experience
- Robust security controls
- Audit capabilities
Negative
- Additional infrastructure requirements
