Question

过去几天我一直试图将我的docker镜像部署到AWS beanstalk，遇到了这个我无法找到解决方案的问题。当我将Dockerrun.aws.json文件上传到我的环境（通过控制台）时，它会抛出此错误

Failed to build Docker image aws_beanstalk/staging-app: Sending build context to Docker daemon 3.072kB Error response from daemon: Dockerfile parse error line 2: EXPOSE requires at least one argument. Check snapshot logs for details.

奇怪的是，在我的Dockerfile中，我的EXPOSE关键字包含端口80作为参数。

Dockerfile：

FROM ubuntu

EXPOSE 80

ADD application.py /application.py
ADD requirements.txt /requirements.txt

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

RUN sudo apt-get -y install python3-pip

# INSTALLING GCC
# RUN sudo apt-get -y install gcc

# DEPENDENCY INSTALATION
RUN python3 -m pip install --upgrade pip
RUN python3 -m pip install -r ./requirements.txt

# SPACY ENGLISH MODEL DOWNLOAD
RUN python3 -m spacy download en

CMD ["python3", "./application.py"]

Dockerrun.aws.json：

 {
     "AWSEBDockerrunVersion": "1",
     "Image" : {
      "Name" : "guppythegod/racheal_entrance_gateway:latest",
       "Update" : "true"
     },
     "Ports" : {
       "ContainerPort" : "80"
     }
 }

这是我在Docker hub上的图片链接： https://hub.docker.com/r/guppythegod/racheal_entrance_gateway

我的所有权限都在运行，保存我图片的存储库是公开的。如果有人能帮助我，我们将不胜感激。

谢谢。

Ports应该是一个数组，如下所示：

{
  "AWSEBDockerrunVersion": "1",
  "Image": {
    "Name": "guppythegod/racheal_entrance_gateway:latest",
    "Update": "true"
  },
  "Ports": [
    {
      "ContainerPort": "80"
    }
  ]
}

Answer 2

设置ENV端口号解决了我的问题，在部署eb deploy之前，另一个提示是git提交所做的更改

DockerFile

FROM node:alpine AS builder

WORKDIR /opt/app

COPY package.json  ./

RUN npm install

COPY . /opt/app

RUN npm run build

FROM nginx

COPY --from=builder /opt/app/build /usr/share/nginx/html

ENV PORT 80
EXPOSE 80

CMD ["nginx", "-g", "daemon off;"]

AWS Elastic Beanstalk和Docker - EXPOSE至少需要一个参数
