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

Question

我正在使用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，并且能够使用该映像在本地以及在EC2实例上创建容器都没有问题。 但是，当使用Beanstalk启动应用程序时，CMD“ npm run prod”无法找到我的package.json文件。 以下是有关我的设置和问题的一些说明：

• 使用Elastic Beanstalk多容器Docker环境
• 将Dockerrun.aws.json文件与两个图像一起使用：Mongo和dockerhub上托管的自定义Node.js Web应用程序图像
• 我可以将映像下拉并使用“ Docker run npm run prod”运行它，并且它可以工作（在本地和EB创建的EC2实例上）
• 当EB尝试使用同一命令启动映像时，它会出错并表示找不到package.json（有关详细信息，请参见下面的错误）。

我不确定是否对Elastic Beanstalk的工作方式有误解，或者是否缺少其他内容。

Dockerrun.aws.json文件（图像名称和环境变量已删除）：

{
"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Web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

package.json中的npm脚本：

"prod": "forever app.js",

来自Docker容器的错误日志：

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

Answer 1

在容器定义中，在mountPoints下，“ / starter”的containerPath值覆盖了/ starter中已经存在的数据。 通过更改值，该应用程序能够启动。

引起问题的容器定义：

    "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
        }
