docker falha com “iptables: sem cadeia / destino / correspondência com esse nome”

Question

Quando tento publicar as portas do contêiner no host, o docker não consegue adicionar as regras do iptables:

$ 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)).

O que me confunde é que a corrente DOCKER parece existir:

$ sudo iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy DROP)

... e também aqui:

RETURN     all  --  anywhere             anywhere            

Talvez seja relevante: ip a mostra que docker0 está inativo:

$ 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

Eu tentei parar a janela de encaixe, remover o dispositivo docker0 quebrado e reiniciar a janela de encaixe novamente. Mesmo erro:

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

ip a ainda mostra que docker0 está inativo. A execução de sudo docker run --rm -p 8080:80 nginx também é executada na mensagem de erro idêntica acima.
