### registry.k8s.io/etcd docker image

Provides docker images containing etcd and etcdctl binaries for multiple etcd
version as well as a migration operator utility for upgrading and downgrading
etcd--it's data directory in particular--to a target version.

#### Versioning

Each `registry.k8s.io/etcd` docker image is tagged with an version string of the form
`<etcd-version>-<image-revision>`, e.g. `3.0.17-0`.  The etcd version is the

	clientv3 "go.etcd.io/etcd/client/v3"
	"google.golang.org/grpc"
	"k8s.io/klog/v2"
)

// CombinedEtcdClient provides an implementation of EtcdMigrateClient using a combination of the etcd v2 client, v3 client
// and etcdctl commands called via the shell.
type CombinedEtcdClient struct {
	cfg *EtcdMigrateCfg
}

// NewEtcdMigrateClient creates a new EtcdMigrateClient from the given EtcdMigrateCfg.

	flags.StringVar(&opts.binDir, "bin-dir", "/usr/local/bin",
		"directory of etcd and etcdctl binaries, must contain etcd-<version> and etcdctl-<version> for each version listed in <bundled-versions>.")
	flags.StringVar(&opts.dataDir, "data-dir", "",
		"etcd data directory of etcd server to migrate. If unset fallbacks to DATA_DIRECTORY env.")
