docker - 无法在主机上访问Dockerized Vue的localhost:8080(尽管使用EXPOSE-ing端口)

在对应用程序进行Docker化后，我无法再通过localhost:8080访问我的Vue应用程序。

我有一个Dockerfile，内容如下:

 # Base the image off of the NodeJS image
 FROM node

 # Set the working directory to be the HOME directory
 WORKDIR /root

 # Install NPM dependencies early in the build process
 COPY ./package.json /root
 COPY ./package-lock.json /root
 RUN npm install

 # Specify what port will be available - necessary for VPC network
 EXPOSE 8080

 # Copy our application files to the image
 COPY ./.browserslistrc /root
 COPY ./.eslintrc.js /root
 COPY ./.env /root
 COPY ./babel.config.js /root
 COPY ./README.md /root
 COPY ./vue.config.js /root
 COPY ./public /root/public
 COPY ./src /root/src

 # Start the container running our Node app
 CMD ["npm", "run", "serve"]

(在进行Dockerizing之前，npm run serve允许我通过Web浏览器访问Vue应用。)

然后我运行PS命令docker build:

PS C:\Users\User\mealSocial-dev> docker build -t finalvue app
Sending build context to Docker daemon  126.8MB
Step 1/15 : FROM node
 ---> 448d0873ea84

...然后docker run -p 8080:8080:

PS C:\Users\User\mealSocial-dev> docker run -p 8080:8080 finalvue

> [email protected] serve /root
> vue-cli-service serve

It seems you are running Vue CLI inside a container.
Access the dev server via http://localhost:<your container's external mapped port>/
Note that the development build is not optimized.
To create a production build, run npm run build.

尽管它说

，我得到This page isn’t working. localhost didn’t send any data. ERR_EMPTY_RESPONSE:

docker - 无法在主机上访问Dockerized Vue的localhost:8080(尽管使用EXPOSE-ing端口)-LMLPHP

我是EXPOSE-在Dockerfile中添加端口并在运行-p 8080:8080时添加docker run标记。我想念什么？

最佳答案

从评论部分:

将--host 0.0.0.0添加到npm run serve
要么

将host: 0.0.0.0添加到配置(./vue.config.js)
