type Backend ¶

type Backend struct {
	IP   string
	Port string
}

Backend represents a backend server that can receive traffic.

type CertLoader ¶

type CertLoader interface {
	GetCertificate(hello *tls.ClientHelloInfo) (*tls.Certificate, error)
}

CertLoader is an interface for loading TLS certificates.

type CertManager ¶

type CertManager struct {
	// contains filtered or unexported fields
}

CertManager manages TLS certificates for the proxy. It loads certificates from disk and reloads when explicitly told to via ReloadCertificates().

func NewCertManager(certDir string, logger *slog.Logger) (*CertManager, error)

func (cm *CertManager) CertificateCount() int

func (cm *CertManager) GetCertificate(hello *tls.ClientHelloInfo) (*tls.Certificate, error)

func (cm *CertManager) HasCertificate(domain string) bool

func (cm *CertManager) ReloadCertificates() error

func (cm *CertManager) SetDomainResolver(resolver DomainResolver)

func (cm *CertManager) Stop()

type Config ¶

type Config struct {
	// Routes maps canonical domains (lowercase) to their route configurations.
	Routes map[string]*Route
	// APIDomain is the domain for the haloy API (lowercase).
	APIDomain string
}

Config holds the proxy configuration.

func BuildConfigFromDeployments(deployments []DeploymentInfo, apiDomain string) (*Config, error)

func BuildConfigFromHaloydDeployments(deployments map[string]HaloydDeployment, apiDomain string) (*Config, error)

type DeploymentInfo ¶

type DeploymentInfo struct {
	AppName   string
	Canonical string
	Aliases   []string
	Instances []InstanceInfo
}

BuildRoutesFromDeployments is a helper function to build routes from a deployment map. This function bridges the gap between the deployment manager's data structure and the proxy's route configuration.

type DomainResolver ¶

type DomainResolver interface {
	ResolveCanonical(domain string) (string, bool)
}

DomainResolver resolves alias domains to canonical domains.

type HaloydDeployment ¶

type HaloydDeployment struct {
	AppName   string
	Domains   []HaloydDomain
	Instances []HaloydInstance
}

ConvertDeployments is a convenience type alias for the deployment map format used by haloyd's DeploymentManager.

type HaloydDomain ¶

type HaloydDomain struct {
	Canonical string
	Aliases   []string
}

type HaloydInstance ¶

type HaloydInstance struct {
	IP   string
	Port string
}

type InstanceInfo ¶

type InstanceInfo struct {
	IP   string
	Port string
}

type Proxy ¶

type Proxy struct {
	// contains filtered or unexported fields
}

Proxy is an HTTP reverse proxy with TLS termination and host-based routing.

func New(logger *slog.Logger, certLoader CertLoader, apiHandler http.Handler) *Proxy

func (p *Proxy) GetConfig() *Config

func (p *Proxy) ResolveCanonical(domain string) (string, bool)

func (p *Proxy) Shutdown(ctx context.Context) error

func (p *Proxy) Start(httpAddr, httpsAddr string) error

func (p *Proxy) UpdateConfig(config *Config)

type Route ¶

type Route struct {
	Canonical string
	Aliases   []string
	Backends  []Backend
}

Route represents a domain route configuration.

type RouteBuilder ¶

type RouteBuilder struct {
	// contains filtered or unexported fields
}

RouteBuilder helps build proxy routes from deployment information.

func NewRouteBuilder() *RouteBuilder

func (rb *RouteBuilder) AddRoute(canonical string, aliases []string, backends []Backend)

func (rb *RouteBuilder) Build() (*Config, error)

func (rb *RouteBuilder) SetAPIDomain(domain string)
