Docker run --network host

Referente ao curso Docker: Criando containers sem dor de cabeça

Olá, estou tentando rodar os container na mesma rede do host mas me parece que assim que o container sobe, ele não consegue obter ip da rede.

Estou executando o seuinte comando

docker run --network host --name teste -p 80:80 -d -it henriqueweiand/micsrv:1.1 bash

A maquina sobe, acesso ela e starto o apache, dei um inspect mas não localizo ip dela... Ao executar

docker ps

A mesma esta ligada porem onde normalmente diz 0.0.0.0:80 -> 80 não esta exibindo nada.

Soluções?
