I've done all the testing I can. I need some help testing the different challenge modes. Also, I need to figure out how we want to create the "internal" ipaddresspools and l2advertisemnets for metallb. Right now we have to manually create that if we try to deploy with an internal httproute. |

This feature adds comprehensive multi-gateway support to the Envoy Gateway setup script,
enabling flexible deployments that can separate external and internal services with
appropriate security configurations.
Features:
- Configuration file mode (--config) for YAML-based multi-gateway setup
- Namespace isolation for each gateway (improved security and organization)
- Hybrid gateway support (external-only, internal-only, or both)
- Flexible certificate management (Let's Encrypt or self-signed per gateway)
- Route and listener processing for multiple gateways
- Support for multiple MetalLB pools per gateway
- Internal gateways accessible on port 443 (same as external)
- Backward compatibility with legacy single gateway mode
Configuration Format:
The new --config option accepts YAML files defining multiple gateways:
gateways:
- name: external-gateway
namespace: external-gateway
domain: cloud.example.com
type: [external]
metallb_pools:
external: gateway-api-external
issuer:
type: letsencrypt
email: [email protected]
routes:
- keystone
- nova
- neutron
Key Improvements:
- Each gateway runs in its own namespace for better isolation
- Routes are automatically created for each gateway type
- Listeners are applied to all gateways
- Support for multiple DNS providers (Cloudflare, Route53, Azure DNS, etc.)
- Comprehensive error handling and validation
Files Added:
- examples/gateway-config.yaml: Comprehensive example configuration
- examples/simple-gateway-config.yaml: Simple setup example
- docs/gateway-setup.md: Complete usage documentation
Files Modified:
- bin/setup-envoy-gateway.sh: Enhanced with multi-gateway support
Backward Compatibility:
- Legacy single gateway mode still works unchanged
- Existing --email, --domain, --challenge options preserved
- Interactive mode still available
- All DNS plugins supported in both modes
