restore

Shows how to restore a Kubernetes cluster by specifying the underlying etcd. It assumes that the etcd process is servering on 127.0.0.1:2379. Takes the backup from Minio play, a public S3-compatible storage sandbox.

// define the URL etcd is available at:
etcdurl := "http://127.0.0.1:2379"

// using Minio play, a public S3-compatible sandbox
// for the remote storage available at https://play.minio.io:9000
// and the following credentials which need to be exposed
// as environment variables to the ReShifter process:
_ = os.Setenv("ACCESS_KEY_ID", "Q3AM3UQ867SPQQA43P2F")
_ = os.Setenv("SECRET_ACCESS_KEY", "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG")

// carry out the restore into etcd underlying the Kubernetes cluster
// and handle errors as they occur:
keysrestored, restoretime, err := Restore(etcdurl, "1498847078", "/tmp", "play.minio.io:9000", "2017-07-some-bucket")
if err != nil {
	log.Fatal(err)
	return
}
fmt.Printf("The restore completed successfully. Restored %d keys in %d seconds.\n", keysrestored, restoretime)

Output:

The restore completed successfully. Restored 1042 keys.
