Mapping node_modules in a Dockerrun.aws.json for use in a container_command

I was wondering what the correct path structure is for doing a Volume mapping in a Dockerrun.aws.json to that I could reference installed node_modules in a '/opt/elasticbeanstalk/hooks/appdeploy/post' bash file. In short, I am trying to run Sequelize migrations after a deploy and cannot seem to expose the node_modules path to the host environment.

My Dockerfile

FROM node:6.10
ENV USER root
RUN mkdir -p /install/
ENV PATH /install/node_modules/.bin:$PATH
ENV NODE_PATH /install/node_modules/
COPY ./package.json /install/package.json
RUN cd install; npm install
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
COPY . /usr/src/app
RUN groupadd -r nodejs && useradd -m -r -g nodejs nodejs
USER nodejs
EXPOSE 3000
CMD [ "npm", "start" ]

Dockerrun.aws.json

{
  "AWSEBDockerrunVersion": "1",
  "Logging": "/var/log/pm2",
  "Volumes": [
    {
      "HostDirectory": "/var/app/current",
      "ContainerDirectory": "/usr/src/app"
    },
    {
      "HostDirectory": "/var/app/current/node_modules",
      "ContainerDirectory": "/install"
    }
  ]
}

This works fine without the '"/var/app/current/node_modules' mapping but fails with it (I'm guessing because the /install directory is invalid)

Thanks, Steve
