Docker Beta13 fs sharing problems

Docker Desktop for Mac

Expected behavior

node.js running a React app based on webpack should be able to handle hot reloading on local code changes.

Actual behavior

To me it seems, that the directory where I mount my application code into the container get’s unmounted in the middle of the process. So webpack then can not continue with it’s job. This only happens after the update from Docker Beta 12 to 13.

This is the last log of my application:

Steps to reproduce the behavior

####My Dockefile:

FROM node:5.4

RUN mkdir /app
WORKDIR /app

COPY package.json /app/
COPY npm-shrinkwrap.json /app/

RUN npm install

####My docker-compose.yml:

version: '2'
services:

  myapp:
    build:
      context: .
      dockerfile: Dockerfile
    command: npm run dev
    ports:
      - "4000:4000"
      - "4001:4001"
      - "3030:3030"

####My docker-compose.override.yml:

version: '2'
services:

  myapp:
    volumes:
      - .:/app
      - /app/node_modules

The app itself is a fork of:

I’ve cloned the react-redux-universal-hot-example repository and put your three files in it but when I run docker-compose up, I see

Step 5 : COPY npm-shrinkwrap.json /app/
ERROR: Service 'myapp' failed to build: lstat npm-shrinkwrap.json: no such file or directory

Could you please advise me about what else I need to run to build and run the container and observe the error? I tried npm shrinkwrap in the repository root but there were lots of errors about missing packages. If you could share your fork or post your npm-shrinkwrap.json or provide a sequence of steps to generate it, I would be very appreciative.

Oh, I see. The initial repository does not come with a shrinkwrap file. So best is just to remove that step from the Dockerfile. It’s safe and should lead to a reproducable situation.

I quickly setup a repo here: https://github.com/janroesner/dckr-rrr

After docker-compose up the app will be available via http://localhost:3000. If you make changes to the code several times and wait for webpack to rebuild and hot-reload the app, the error will come up. At least with #13. I just switched back to #11 where all things work like expected.

Experiencing something similar with a python container:
OSError: [Errno 107] Socket not connected: '/usr/share/src/core/collections/__init__.py'
