Overview ¶
Package eskipfile implements the DataClient interface for reading the skipper route definitions from an eskip formatted file.
(See the DataClient interface in the skipper/routing package and the eskip format in the skipper/eskip package.)
The package provides two implementations: one without file watch (legacy version) and one with file watch. When running the skipper command, the one with watch is used.
Example ¶
package main
import (
"github.com/zalando/skipper/eskipfile"
"github.com/zalando/skipper/proxy"
"github.com/zalando/skipper/routing"
)
func main() {
// open file with a routing table:
dataClient := eskipfile.Watch("/some/path/to/routing-table.eskip")
defer dataClient.Close()
// create a routing object:
rt := routing.New(routing.Options{
DataClients: []routing.DataClient{dataClient},
})
defer rt.Close()
// create an http.Handler:
p := proxy.New(rt, proxy.OptionsNone)
defer p.Close()
}

Functions ¶
func RemoteWatch ¶ added in v0.13.41
func RemoteWatch(o *RemoteWatchOptions) (routing.DataClient, error)
RemoteWatch creates a route configuration client with (remote) file watching. Watch doesn't follow file system nodes, it always reads (or re-downloads) from the file identified by the initially provided file name.
Types ¶
type Client ¶
type Client struct {
// contains filtered or unexported fields
}
Client contains the route definitions from an eskip file, if you need file watch use WatchClient instead.
Use the Open function to create instances of Client.
func Open ¶
Open opens an eskip file and parses it, returning a DataClient implementation. If reading or parsing the file fails, returns an error. This implementation doesn't provide file watch.
func (Client) LoadAndParseAll ¶
func (Client) LoadUpdate ¶
LoadUpdate is a noop.
type RemoteWatchOptions ¶ added in v0.13.41
type RemoteWatchOptions struct {
// URL of the route file
RemoteFile string
// Verbose mode for the dataClient
Verbose bool
// Amount of route changes that will trigger logs after route updates
Threshold int
// It does an initial download and parsing of remote routes, and makes RemoteWatch to return an error
FailOnStartup bool
// HTTPTimeout is the generic timeout for any phase of a single HTTP request to RemoteFile.
HTTPTimeout time.Duration
}
type WatchClient ¶ added in v0.9.206
type WatchClient struct {
// contains filtered or unexported fields
}
WatchClient implements a route configuration client with file watching. Use the Watch function to initialize instances of it.
func Watch ¶ added in v0.9.206
func Watch(name string) *WatchClient
Watch creates a route configuration client with file watching. Watch doesn't follow file system nodes, it always reads from the file identified by the initially provided file name.
func (*WatchClient) Close ¶ added in v0.9.206
func (c *WatchClient) Close()
Close stops watching the configured file and providing updates.
func (*WatchClient) LoadAll ¶ added in v0.9.206
func (c *WatchClient) LoadAll() ([]*eskip.Route, error)
LoadAll returns the parsed route definitions found in the file.
func (*WatchClient) LoadUpdate ¶ added in v0.9.206
func (c *WatchClient) LoadUpdate() ([]*eskip.Route, []string, error)
LoadUpdate returns differential updates when a watched file has changed.
func (*WatchClient) Name ¶ added in v0.24.85
func (*WatchClient) Name() string
