Question

我在Dockerfile中有这个多阶段构建：

## Stage 1
FROM node:9 as builder

RUN apt-get update && apt-get -y install sudo
RUN echo "newuser ALL=(ALL) NOPASSWD:ALL" >> /etc/sudoers

RUN useradd -ms /bin/bash newuser
USER newuser
RUN mkdir -p /home/newuser/app
WORKDIR /home/newuser/app

RUN sudo chown -R $(whoami) $(npm config get prefix)/lib
RUN npm set progress=false
RUN npm config set depth 0
RUN npm cache clean --force

COPY dist .

## Stage 2
FROM php:5.6.30

RUN apt-get update && apt-get -y install sudo
RUN echo "newuser ALL=(ALL) NOPASSWD:ALL" >> /etc/sudoers

RUN useradd -ms /bin/bash newuser
USER newuser
RUN mkdir -p /home/newuser/app
WORKDIR /home/newuser/app

COPY --from=builder /home/newuser/app /home/newuser/app

RUN ls -a /home/newuser/app

CMD ["php", "-S", "localhost:3000"]

图像构建成功，使用：

  docker build -t x .

然后我用：

运行它

   docker run -p 3000:3000 x

但是当我在主机上访问localhost：3000时，我没有得到回复。网页是空白的。

有谁知道为什么会这样？

我也尝试过：

CMD ["sudo", "php", "-S", "localhost:80"]

和

  docker run -p 3000:80 x

以及其他一些变化，仍然没有。

不确定为什么PHP静态服务器不起作用，但我使用Node.js静态服务器包：

FROM node:9 as builder

RUN apt-get update && \
      apt-get -y install sudo

RUN echo "newuser ALL=(ALL) NOPASSWD:ALL" >> /etc/sudoers

RUN useradd -ms /bin/bash newuser
USER newuser
RUN mkdir -p /home/newuser/app
WORKDIR /home/newuser/app

RUN sudo chown -R $(whoami) $(npm config get prefix)/lib
RUN sudo chown -R $(whoami) $(npm config get prefix)/lib/node_modules
RUN sudo chown -R $(whoami) $(npm config get prefix)/bin
RUN sudo chown -R $(whoami) $(npm config get prefix)/share
RUN sudo chown -R $(whoami) /usr/local/lib

RUN npm set progress=false
RUN npm config set depth 0
RUN npm cache clean --force

COPY dist .

RUN npm install -g http-server

ENTRYPOINT ["http-server", "."]

你是这样构建的：

docker build -t x .

然后像这样运行它：

docker run -p 3000:8080 x

使用PHP静态Web服务器无法将端口从容器暴露给主机
