I'm trying to dockerize my create-react-app development environment and preserving hot reloads. According to most guides (and this guy), the most direct way is docker run -p 3000:3000 -v "$(pwd):/var/www" -w "/var/www" node npm start in the project folder.
However, I'm getting this error instead:
$ docker run -p 3000:3000 -v "$(pwd):/var/www" -w "/var/www" node npm start
> my-app#0.1.0 start /var/www

I'm running on Windows. I believe mounting the volume might have some permission issues leading to the input/output error, but testing various settings didn't work out. I'm honestly stumped. All I want is to run my app in Docker with hot reload for development.
As it turns out, setting up create-react-app in docker takes a little more work.
The primary issue is that mounted volumes are not available in the build step, so when node npm start runs the mounted project files technically don't exist yet.
As such, you need to copy over and install the project first to let it run the first time before the volume mounts. Hot reloading works normally afterwards.
Here's my final working setup:
docker-compose.yml:
create-react-app:
build:
context: create-react-app
ports:
- 3000:3000
environment:
- NODE_PATH=/node_modules
- CHOKIDAR_USEPOLLING=true
volumes:
- ./create-react-app:/create-react-app
Dockerfile:
FROM node:alpine
# Extend PATH
ENV PATH=$PATH:/node_modules/.bin
# Set working directory
WORKDIR /client
# Copy project files for build
ADD . .
# Install dependencies
RUN npm install
# Run create-react-app server
CMD ["npm", "run", "start"]

In my Dockerfile in docker/my-project-node/ folder I have RUN npm i --legacy-peer-deps --only=production --no-optional.
I want to run docker build locally and see if everything works fine.
When I run docker build -t my-project-image . I get this npm error:
#9 0.913 npm ERR! code ENOENT
#9 0.913 npm ERR! syscall open

What's wrong in my docker file?
You are passing the wrong build context to docker.
The build context is the directory Docker starts working from and all the COPY commands find the files from this path.
There are 2 ways to properly specify this:
Run the command from the root of your project and specify the Dockerfile path explicitly if its not on the root. docker build -t my-web-app -f docker/my-project-node/Dockerfile
In the docker command, specify the root you want. docker build -t my-web-app ../.. (as your root is 2 folders up)
Finally, please look at docker-compose. All these pesky docker commands can be beautifully represented in a docker-compose file like this:
# docker-compose.yaml placed at root of the project
version: '3'
services:
web:
container_name: "example1"
build:
context: .
dockerfile: docker/my-project-node/Dockerfile
ports:
- "8000:8000"
Once the file is created, simply run docker-compose up -d to create and run the containers, and docker-compose down to shutdown and remove the containers :)
I am trying to create and run a Docker image of my Angular application. It works perfectly fine locally however I am having problems when it is coming to the docker run command.
My Dockerfile is:
FROM node:current
#FROM node:current-slim
#FROM node:12.13.1-alpine
WORKDIR /usr/src/app
COPY package.json .
COPY proxy.conf.json .
RUN npm install
EXPOSE 4200
CMD [ "npm", "run", "dev" ]
In my package.json the scripts are:
"dev": "concurrently \"npm start\" \"ng serve --proxy-config proxy.conf.json\""
and the two Docker commands I am running are:
docker build --tag fuel-consumption-front:0.0.0 .
docker run --publish 8000:4200 --detach --name fuel fuel-consumption-front:0.0.0
The Docker logs are saying (or this is the output on my desktop Docker application for this):
> fuel-consumption-front#0.0.0 dev /usr/src/app
> concurrently "npm start" "ng serve --proxy-config proxy.conf.json"
sh: 1: concurrently: not found
npm ERR! code ELIFECYCLE

npm ERR! A complete log of this run can be found in:

It is the first line that is making me think this is something to do with concurrently not being able to be run
I have tried different node images (commented out in the Dockerfile) and also npm insall -g within the Dockerfile. There is not an entry for concurrentrly in the package.json file either. All different methods are throwing up the same error
I am pretty new with Docker and was using the example from the Docker pages as a template. Their example worked perfectly fine when doing this.
I had more of a play with this after leaving it for a while. Turned out I didn't save my Dockerfile when I added npm install concurrently. Now the Dockerfile reads (with a few more tweaks):
FROM node:current-slim
WORKDIR /usr/src/app
COPY package.json .
COPY proxy.conf.json .
RUN npm install
RUN npm install concurrently
COPY . .
EXPOSE 4200
CMD [ "npm", "run", "dev" ]
Now onto the next issue....need to make the image smaller and it says it compiles fine in the logs but can't connect on localhost:8000 (another problem for another day!)
I'm doing the try it out section in loopback4 oficial site:
https://loopback.io/doc/en/lb4/Authentication-Tutorial.html
But when i try to execute the next command:
npm run docker:start
I get the following error:

I tried to change the route and searched for answers on google but nothing solved my problem
npm run docker:start start a bash script behind the scene if you look into package.json,
"docker:start": "./bin/start-dbs.sh",
While you are using the window, so might be the case something wrong the script in window. You can try two option
Run the command in git bash
Run the command manually without npm
you can run these command which npm run docker:start does in pacakge.json
docker run --name mongo -p 27017:27017 -d mongo:latest
docker run --name redis -p 6379:6379 -d redis:latest
I'm trying to npm install by Docker container:
This is a DockerFile:
# default /var/www/html (mapped to .../code folder with projects)
FROM node
WORKDIR /work
# Additional tools (ng, gulp, bower)
RUN npm install -g #angular/cli bower gulp grunt
CMD while true; do sleep 10000; done
EXPOSE 3002 3003 3004
I run and map it with this command:
docker run -d --name node-cmd -p 3002:3002 -p 3003:3003 -p 3004:3004 -v
/m/dockerlogs/node-cmd/logs:/root/.npm/_logs -v /m/projekty:/work node-cmd
I log in to this container with:
docker exec -it node-cmd bash -c "cd /code; bash"
After I run npm install (https://github.com/gdi2290/angular-starter), I write this from logged in container
But I'm getting this error after installation
npm ERR! Maximum call stack size exceeded

My npm version is 6.4.1
I have a Windows 8.1 and Docker Toolbox
But when I write npm install on Windows without Docker all is OK.
It might be because of different node versions. Check your node version with node -v and use that for the Dockerfile. Check the supported tags and Dockerfile links here: https://hub.docker.com/_/node
In the Dockerfile, I changed from FROM node:alpine AS node_builder to FROM node:lts-alpine AS node_builder and now it works.
Ok, i solved this problem, I was use npm install with --no-bin-links flag. Thanks for answers :)
For me, this ended up being caused by permission issues (I had previously install node_modules outside of docker). Deleting node_modules and only installing from within docker corrected the problem.
I'm fairly new to docker and I'm kind of experimenting with Angular CLI app. I managed to run it locally through my docker container. It works great, but when I try running it from my server it fails.
Server is hosted on DigitalOcean:
512 MB Memory / 20 GB Disk / FRA1 - Ubuntu Docker 17.03.0-ce on 14.04
I used dockerhub to transfer my container to the server.
When logging the container it gives me this:

How come it runs locally and fails on server? Am I missing some dependencies?
ng serve is an angular-cli command. I'm guessing you need to install it globally in your docker file if you want to start your server like that on digital ocean:
RUN npm i -g angular-cli
I think it would be more typical to simply run the app using the naked node server in production. So your CMD would look more like this:
CMD ["node", "app.js"]
