With CoreDNS now supporting etcdv3 as the DNS backend, we can update our federation target to etcdv3. Users will now be able to use etcdv3 server as the federation backbone. Minio will update bucket data to etcdv3 and CoreDNS can pick that data up and serve it as bucket style DNS path.

// Package context defines the Context type, which carries deadlines,
|
|
// cancelation signals, and other request-scoped values across API boundaries
|
|
// and between processes.
|
|
// As of Go 1.7 this package is available in the standard library under the
|
|
// name context. https://golang.org/pkg/context.
|
|
//
|
|
// Incoming requests to a server should create a Context, and outgoing calls to
|
|
// servers should accept a Context. The chain of function calls between must
|
|
// propagate the Context, optionally replacing it with a modified copy created
|
|
// using WithDeadline, WithTimeout, WithCancel, or WithValue.
|
|
//
|
|
// Programs that use Contexts should follow these rules to keep interfaces
|
|
// consistent across packages and enable static analysis tools to check context
|
|
// propagation:
|
|
//
|
|
// Do not store Contexts inside a struct type; instead, pass a Context
|
|
// explicitly to each function that needs it. The Context should be the first
|
|
// parameter, typically named ctx:
|
|
//
|
|
// func DoSomething(ctx context.Context, arg Arg) error {
|
|
// // ... use ctx ...
|
|
// }
|
|
//
|
|
// Do not pass a nil Context, even if a function permits it. Pass context.TODO
|
|
// if you are unsure about which Context to use.
|
|
//
|
|
// Use context Values only for request-scoped data that transits processes and
|
|
// APIs, not for passing optional parameters to functions.
|
|
//
|
|
// The same Context may be passed to functions running in different goroutines;
|
|
// Contexts are safe for simultaneous use by multiple goroutines.
|
|
//
|
|
// See http://blog.golang.org/context for example code for a server that uses
|
|
// Contexts.
|
|
package context // import "golang.org/x/net/context"
|
|
|
|
// Background returns a non-nil, empty Context. It is never canceled, has no
|
|
// values, and has no deadline. It is typically used by the main function,
|
|
// initialization, and tests, and as the top-level Context for incoming
|
|
// requests.
|
|
func Background() Context {
|
|
return background
|
|
}
|
|
|
|
// TODO returns a non-nil, empty Context. Code should use context.TODO when
|
|
// it's unclear which Context to use or it is not yet available (because the
|
|
// surrounding function has not yet been extended to accept a Context
|
|
// parameter). TODO is recognized by static analysis tools that determine
|
|
// whether Contexts are propagated correctly in a program.
