Functions

func GetEtcdClient

func GetEtcdClient(ctx context.Context, certificates *Certificates, endpoints ...string) (*clientv3.Client, error)

GetEtcdClient returns an etcd client connected to the specified endpoints. If no endpoints are provided, endpoints are retrieved from the provided runtime config. If the runtime config does not list any endpoints, the default endpoint is used. The returned client should be closed when no longer needed, in order to avoid leaking GRPC client goroutines.

func WaitForEtcd

func WaitForEtcd(parentCtx context.Context, certificates *Certificates, endpoints ...string) error
