docker が "iptables: No chain/target/match by that name" で失敗します。

コンテナのポートをホストに公開しようとすると、dockerはiptablesルールを追加しません。

$ sudo docker run --rm -p 8080:80 nginx
docker: Error response from daemon: driver failed programming external 
connectivity on endpoint:

iptables failed:
  iptables --wait -t nat -A DOCKER -p tcp -d 0/0
           --dport 8080 -j DNAT --to-destination 172.17.0.2:80 ! -i docker0

 iptables: No chain/target/match by that name. (exit status 1)).

私を混乱させるのは、次のようなDOCKERチェーンが存在するようです。

$ sudo iptables -L

たぶん関連があるかもしれません：ip aディスプレイがdocker0消えています：

$ ip a
...
74: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default 
    link/ether 02:42:01:52:de:7d brd ff:ff:ff:ff:ff:ff
    inet 172.17.0.1/16 brd 172.17.255.255 scope global docker0
       valid_lft forever preferred_lft forever

ドッカーを停止し、破損したdocker0デバイスを取り除いた後、ドッカーを再起動してみました。同じエラー：

sudo systemctl stop docker.service
sudo ip link del docker0
sudo systemctl start docker.service

ip aまだdocker0下落傾向を見せています。実行時にもsudo docker run --rm -p 8080:80 nginx 上記のエラーメッセージが表示されます。
