thank you for helping.  
on host machine didn’t work DNS-query

```plaintext
dig NS tut.by @8.8.8.8

; <<>> DiG 9.11.3-1ubuntu1-Ubuntu <<>> NS tut.by @8.8.8.8
;; global options: +cmd
;; connection timed out; no servers could be reached

```

I took ip address from networking interface and add to docker settings

```plaintext
dig NS tut.by @172.30.0.55

; <<>> DiG 9.11.3-1ubuntu1-Ubuntu <<>> NS tut.by @172.30.0.55
