Question

我基于nodejs创建了一个docker-container。但是，它似乎运行良好，但是localhost：8080和localhost：8443以及localhost无法连接。另外，使用curl的连接会产生以下消息：

$ curl -vvv localhost:8080
*   Trying ::1:8080...
* TCP_NODELAY set
* Connected to localhost (::1) port 8080 (#0)
> GET / HTTP/1.1
> Host: localhost:8080
> User-Agent: curl/7.67.0
> Accept: */*
> 
* Recv failure: Connection reset by peer
* Closing connection 0
curl: (56) Recv failure: Connection reset by peer
$ curl -vvv localhost:8443
*   Trying ::1:8443...
* TCP_NODELAY set
* Connected to localhost (::1) port 8443 (#0)
> GET / HTTP/1.1
> Host: localhost:8443
> User-Agent: curl/7.67.0
> Accept: */*
> 
* Recv failure: Connection reset by peer
* Closing connection 0
curl: (56) Recv failure: Connection reset by peer

这是docker-compose.yml

version: "2"
services:
  app:
    container_name: app_test
    restart: always
    build: .
    ports:
      - "8080:8080"
      - "8443:8443"

这是Dockerfile

FROM node:10.12.0

WORKDIR /usr/src/app

COPY package.json ./

RUN npm install

COPY . .

EXPOSE 80 # I try 3000, 8080 instead 80

CMD [ "node", "app.js" ]

这是docker ps

的结果

docker ps
CONTAINER ID        IMAGE                       COMMAND                  CREATED             STATUS              PORTS                                                    NAMES
735fba0a6ff5        IMAGE_NAME                  "node app.js"            46 seconds ago      Up 45 seconds       0.0.0.0:8080->8080/tcp, 80/tcp, 0.0.0.0:8443->8443/tcp   app_test

curl和浏览器均未运行。我该怎么办？

（我很尴尬，因为我不会说英语。请理解。）

Answer 1

version: "2"
services:
  app:
    container_name: app_test
    restart: always
    build: .
    ports:
      - "8080:3000"
      - "8443:8443"

如果您要在localhost：8080上访问您的应用，这应该工作。节点应用程序在标准端口3000上提供。

所以基本上：

{端口主机} ： {端口实际上在容器内部运行}

如何使用本地主机连接Docker容器？
