Question

我使用Elastic beanstalk使用nodejs容器和mongodb容器启动应用程序。我已经为节点web应用程序创建了自己的映像，并且我能够使用此映像在本地创建容器，并且在EC2实例上创建容器而没有任何问题。当使用Beanstalk来启动应用程序时，CMD“npm run prod”无法找到我的package.json文件。以下是关于我的设置和问题的一些注意事项：

使用Elastic Beanstalk Multicontainer Docker环境
使用带有两个图像的Dockerrun.aws.json文件：Mongo，以及在dockerhub上托管的自定义nodejs web应用程序图像
我可以将图像拉下来并使用'Docker run npm run prod'运行它并且它可以工作（本地和EB创建的EC2实例）
当EB尝试启动图像时（使用相同的命令），它出错并说它无法找到package.json（详见下面的错误）。

我不确定我是否对Elastic Beanstalk的工作方式存在误解，或者我是否还有其他错误。

Dockerrun.aws.json文件（图片名称和env vars已删除）：

{
"AWSEBDockerrunVersion": 2,
"volumes": [
    {
        "name": "mongo-vol",
        "host": {
            "sourcePath": "/var/app/mongo-vol"
        }
    },
    {
        "name": "web-vol",
        "host": {
            "sourcePath": "/var/app/web-vol"
        }
    }
],
"containerDefinitions": [
    {
        "name": "mongo",
        "image": "mongo:3.4",
        "essential": false,
        "memory": 128
    },
    {
        "name": "web",
        "image": "<IMAGE NAME>",
        "essential": true,
        "memory": 128,
        "portMappings": [
            {
                "hostPort": 80,
                "containerPort": 3000
            }
        ],
        "links": [
            "mongo"
        ],
        "mountPoints": [
            {
                "sourceVolume": "web-vol",
                "containerPath": "/starter",
                "readOnly": false
            }
        ]
    }
]
}

节点网络应用程序的Dockerfile：

FROM node:6-slim
COPY . /starter
COPY package.json /starter/package.json
WORKDIR /starter
ENV NODE_ENV production
RUN yarn install --production
RUN npm install forever -g
CMD npm run prod
EXPOSE 8888

来自package.json的

npm脚本：

"prod": "forever app.js",

来自docker容器的错误日志：

将CMD更改为bash -c后的错误日志“pwd＆amp;＆amp; ls -alh＆amp;＆amp; npm run prod”

在容器定义中，在mountPoints下，'/ starter'的containerPath值超过了写入/ starter中已经存在的数据。通过更改值，应用程序就可以启动了。

导致问题的容器定义：

    "mountPoints": [
        {
            "sourceVolume": "web-vol",
            "containerPath": "/starter",
            "readOnly": false
        }

修改后的容器定义：

    "mountPoints": [
        {
            "sourceVolume": "web-vol",
            "containerPath": "/web-data",
            "readOnly": false
        }

Elastic Beanstalk / Docker - 没有这样的文件或目录package.json
