Docker Compose不绑定端口

Question

Docker Compose不绑定端口

我的容器有以下Dockerfile:

FROM        centos:centos7

# Install software
RUN         yum -y update && yum clean all
RUN         yum install -y tar gzip wget && yum clean all

# Install io.js
RUN         mkdir /root/iojs
RUN         wget https://iojs.org/dist/v1.1.0/iojs-v1.1.0-linux-x64.tar.gz
RUN         tar -zxvf iojs-v1.1.0-linux-x64.tar.gz -C /root/iojs
RUN         rm -f iojs-v1.1.0-linux-x64.tar.gz

# add io.js to path
RUN         echo "PATH=$PATH:/root/iojs/iojs-v1.1.0-linux-x64/bin" >> /root/.bashrc

# go to /src
WORKDIR     /src

CMD         /bin/bash

我构建这个容器并启动图像docker run -i -t -p 8080:8080 -v /srv/source:/usr/src/app -w /usr/src/app --rm iojs-dev bash.Docker将端口8080绑定到主机端口8080,以便我可以从我的客户端访问iojs-application.一切正常.

现在我想用docker-compose启动我的容器,使用以下docker-compose.yml

webfrontend:
    image: iojs-dev
    links:
        - db
    command: bash -c "iojs test.js"
    ports:
        - "127.0.0.1:8080:8080"
    volumes:
        - /srv/source:/usr/src/app
        - /logs:/logs
db:
    image: mariadb
    environment:
        MYSQL_ROOT_PASSWORD: 12345

当我现在运行时,docker-compose run webfrontend bash我无法访问主机上的端口8080.没有端口绑定.结果docker ports为空,并且docker inspect在端口设置中结果为空:
