Overview ¶
Package discovery provides a common interface for all providers and Match to transform source to destination URL. Run func starts event loop checking all providers and retrieving lists of rules. All lists combined into a merged one.

Functions ¶
func ParseOnlyFrom ¶ added in v1.1.0
ParseOnlyFrom parses comma separated list of IPs
Types ¶
type MatchedRoute ¶ added in v0.6.0
MatchedRoute contains a single match used to produce multi-matched Matches
type Matches ¶ added in v0.6.0
type Matches struct {
MatchType MatchType
Routes []MatchedRoute
}
Matches returns result of url mapping. May have multiple routes. Lack of any routes means no match was wound
type Provider ¶
type Provider interface {
Events(ctx context.Context) (res <-chan ProviderID)
List() (res []URLMapper, err error)
}
Provider defines sources of mappers
type ProviderID ¶
type ProviderID string
ProviderID holds provider identifier to emulate enum of them
const ( PIDocker ProviderID = "docker" PIStatic ProviderID = "static" PIFile ProviderID = "file" PIConsulCatalog ProviderID = "consul-catalog" )
enum of all provider ids
type ProviderMock ¶
type ProviderMock struct {
// EventsFunc mocks the Events method.
EventsFunc func(ctx context.Context) <-chan ProviderID
// ListFunc mocks the List method.
ListFunc func() ([]URLMapper, error)
// contains filtered or unexported fields
}
ProviderMock is a mock implementation of Provider.
func TestSomethingThatUsesProvider(t *testing.T) {
// make and configure a mocked Provider
mockedProvider := &ProviderMock{
EventsFunc: func(ctx context.Context) <-chan ProviderID {
panic("mock out the Events method")
},
ListFunc: func() ([]URLMapper, error) {
panic("mock out the List method")
},
}
// use mockedProvider in code that requires Provider
// and then make assertions.
}
func (*ProviderMock) Events ¶
func (mock *ProviderMock) Events(ctx context.Context) <-chan ProviderID
Events calls EventsFunc.
func (*ProviderMock) EventsCalls ¶
func (mock *ProviderMock) EventsCalls() []struct { Ctx context.Context }
EventsCalls gets all the calls that were made to Events. Check the length with:
len(mockedProvider.EventsCalls())
func (*ProviderMock) List ¶
func (mock *ProviderMock) List() ([]URLMapper, error)
List calls ListFunc.
func (*ProviderMock) ListCalls ¶
func (mock *ProviderMock) ListCalls() []struct { }
ListCalls gets all the calls that were made to List. Check the length with:
len(mockedProvider.ListCalls())
type RedirectType ¶ added in v0.8.0
type RedirectType int
RedirectType defines types of redirects
const ( RTNone RedirectType = 0 RTPerm RedirectType = 301 RTTemp RedirectType = 302 )
enum of all redirect types
type Service ¶
type Service struct {
// contains filtered or unexported fields
}
Service implements discovery with multiple providers and url matcher
func NewService ¶
NewService makes service with given providers
func (*Service) CheckHealth ¶ added in v0.6.0
CheckHealth starts health-check for service's mappers
func (*Service) Match ¶
Match url to all mappers. Returns Matches with potentially multiple destinations for MTProxy. For MTStatic always a single match because fail-over doesn't supported for assets
func (*Service) Run ¶
Run runs blocking loop getting events from all providers and updating all mappers on each event
func (*Service) ScheduleHealthCheck ¶ added in v0.6.0
ScheduleHealthCheck starts background loop with health-check
type URLMapper ¶
type URLMapper struct {
Server string
SrcMatch regexp.Regexp
Dst string
ProviderID ProviderID
PingURL string
MatchType MatchType
RedirectType RedirectType
KeepHost *bool
OnlyFromIPs []string
AssetsLocation string // local FS root location
AssetsWebRoot string // web root location
AssetsSPA bool // spa mode, redirect to webroot/index.html on not found
// contains filtered or unexported fields
}
URLMapper contains all info about source and destination routes
