syscall: 'spawn xdg-open' inside docker - reactjs

I am build my page inside the docker, and then after I build finish it, it should be push to docker hub. and then I want to deploy it like:
docker run -d --name commerce_dash -p4505:8000 -e NODE_ENV=production r2day/commerce-dash
everything works fine, for now. but When I check the logs, and it shows me:
VITE v3.2.2 ready in 641 ms

# ENV NEXT_TELEMETRY_DISABLED 1
CMD ["node_modules/.bin/vite", "--host", "0.0.0.0", "--port", "8000"]
Anyway, I can run it on my MacBook by using
node_modules/.bin/vite

Docker container can't find pdf from directory

I have a next.js app that contains a pdf file in pdfs/example.pdf. However when I run my docker image I get a 404 error in the pdf viewer on the webpage.
below is my dockerfile:

this is my Dockerfile.
docker builds the react app and it prompts me to goto localhost:3000 where the app is running. But when I goto localhost:3000. I shows connection refused.
In your Dockerfile you copy in folder App everything to app/
And in your docker-compose you map /app to /app/node_modules.
This will not work.
Choose 1 of the two, and my instinct (and many error in the past) tell me that you should build everything in Dockerfile, including copying node_modules, and don't touch it in docker-compose.

Use npm run build serveral times

I have a React App and I need to run it in docker. Inside this container I need to build 3 instance with the same code, but with different environments by replacing .env.production with my .env.production2 and .env.production3 file. I have a problem with dockerfile: if I'm not use RUN npm install after changing WORKDIR - build stops with error:
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
npm WARN Local package.json exists, but node_modules missing, did you mean to install?
So right now it works only with this dockerfile:
FROM node:12 as build-box
COPY . /app/expert
COPY . /app/expert-control-chat
COPY . /app/expert-control-support
WORKDIR /app/expert
ARG NPMTOKEN
ENV NPMTOKEN=$NPMTOKEN
RUN npm config set _auth $NPMTOKEN
RUN npm install
# Build
FROM build-box as publish
WORKDIR /app/expert
RUN npm run build
WORKDIR /
RUN rm -rf /app/expert-control-chat/.env.production
COPY .env.production.chat-control /app/expert-control-chat/.env.production
WORKDIR /app/expert-control-chat
RUN npm install
RUN npm run build
WORKDIR /
RUN rm -rf /app/expert-control-support/.env.production
COPY .env.production.chat-support /app/expert-control-support/.env.production
WORKDIR /app/expert-control-support
RUN npm install
RUN npm run build
FROM nginx as runtime
RUN rm -rf /etc/nginx/conf.d
COPY nginx.conf /etc/nginx/nginx.conf
WORKDIR /app/expert
COPY --from=publish /app/expert/build ./
WORKDIR /app/expert-control-chat
COPY --from=publish /app/expert-control-chat/build ./
WORKDIR /app/expert-control-support
COPY --from=publish /app/expert-control-support/build ./
# Start
EXPOSE 3000
CMD ["nginx", "-g", "daemon off;"]
Can you tell me the correct way to make a build?
I think that there is another way to build it, but I can't get that.

npm run tests in docker with travis CI

I am deploying a react app to Heroku via TravisCI. The fact that I'm using Heroku doesn't really affect what I'm about to ask, I'm pretty sure, it's just there for context. Travis successfully deploys the app until I add a testing step (the script section) in .travis.yml:
language: generic
sudo: required
services:
- docker
before_install:
- docker build -t myapp:prod -f Dockerfile.prod .
script:
- docker run -e CI=true myapp:prod npm run test
after_success:
- docker build -t myapp:prod -f Dockerfile.prod .
- echo "$DOCKER_PASSWORD" | docker login -u "$DOCKER_ID" --password-stdin
- docker push myapp:prod
deploy:
provider: heroku
app: myapp
skip_cleanup: true
api_key:
secure: <my_key>
However, my Dockerfile.prod is a multi-stage node + nginx where the nginx stage doesn't keep any node or npm stuff:
# build environment
FROM node:13.12.0-alpine as builder
# set working directory
WORKDIR /app
# add `/app/node_modules/.bin` to $PATH
ENV PATH /app/node_modules/.bin:$PATH
# install app dependencies
COPY package.json ./
COPY package-lock.json ./
# some CI stuff I guess
RUN npm ci
RUN npm install react-scripts#3.4.1 -g --silent
COPY . ./
RUN npm run build
# production environment
FROM nginx:stable-alpine
COPY nginx.conf /etc/nginx/conf.d/default.conf
# If using React Router
COPY --from=builder /app/build /usr/share/nginx/html
# For Heroku
CMD sed -i -e 's/$PORT/'"$PORT"'/g' /etc/nginx/conf.d/default.conf && nginx -g 'daemon off;'
Therefore, it is my understanding that .travis.yml tries to run that npm run test command inside my nginx container and can't execute npm commands (no node installed, right?). So guided by SO answers such as this one I started adding commands into that nginx stage such as
COPY package.json ./
COPY package-lock.json ./
RUN apk add --update npm
but I realized I might be approaching this the wrong way. Should I perhaps be adding npm through Travis? That is, should I include in .travis.yml in the scripts section something like docker run -e CI=true myapp:prod apk add --update npm and whatever else is necessary? This would result in a smaller nginx image no? However, would I run into problems with package.json from the node stage in Dockerfile.prod or anything like that?
In summary, to use TravisCI to test a dockerized react app served with nginx, at what point should I install npm into my image? Does it happen as part of script in .travis.yml or does it happen in Dockerfile.prod? If it is recommened to npm run tests inside Dockerfile.prod, would I do that in the first stage (node) or the second (nginx)?
Thanks
EDIT: Not sure if this can be considered solved, but a user on Reddit recommended to simply RUN npm run test right before the RUN npm run build.

"Create React App" with Docker

I was wondering if anyone had any experience using create-react-app with docker. I was able to get it set up with a Dockerfile like:
from node
RUN mkdir /src
WORKDIR /src
ADD package.json /src/package.json
RUN npm install
EXPOSE 3000
CMD [ "npm", "start" ]
And then used a docker-compose file like:
app:
volumes:
- "./app:/src"
ports:
- "3000:3000"
- "35729:35729"
build: ./app
This allowed me to start up the container and view the app. However livereload didn't work when saving files in the mounted volume and webpack created several .json.gzip files in the src directory.
Any suggestions for getting this working correctly?
Yeah, as aholbreich mentioned, I'd use npm install / npm start locally on my machine for development, just because it's so easy. It's probably possible with docker-compose, mounting volumes etc. too, but I think it could be a bit fiddly to set up.
For deployment you can then very easily use a Dockerfile. Here's an example Dockerfile I'm using:
FROM node:6.9
# Create app directory
RUN mkdir -p /src/app
WORKDIR /src/app
# to make npm test run only once non-interactively
ENV CI=true
# Install app dependencies
COPY package.json /src/app/
RUN npm install && \
npm install -g pushstate-server
# Bundle app source
COPY . /src/app
# Build and optimize react app
RUN npm run build
EXPOSE 9000
# defined in package.json
CMD [ "npm", "run", "start:prod" ]
You need to add the start:prod option to your package.json:
"scripts": {
"start": "react-scripts start",
"start:prod": "pushstate-server build",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject"
},
You can run the tests on your CI service with:
docker run <image> npm test
There's nothing stopping you from running this docker container locally as well to make sure things work as expected.
I recently made a small project called hello-docker-react who just does what the op is looking for.
It's made with docker-compose, create-react-app, yarn, a node image, and a small entrypoint script.
Live reload work flawlessly and I haven't found any problems yet.
https://github.com/lopezator/hello-docker-react
here is good gide for this
https://mherman.org/blog/dockerizing-a-react-app/
for development
# base image
FROM node:9.6.1
# set working directory
RUN mkdir /usr/src/app
WORKDIR /usr/src/app
# add `/usr/src/app/node_modules/.bin` to $PATH
ENV PATH /usr/src/app/node_modules/.bin:$PATH
# install and cache app dependencies
COPY package.json /usr/src/app/package.json
RUN npm install --silent
RUN npm install react-scripts#1.1.1 -g --silent
# start app
CMD ["npm", "start"]
for production
# build environment
FROM node:9.6.1 as builder
RUN mkdir /usr/src/app
WORKDIR /usr/src/app
ENV PATH /usr/src/app/node_modules/.bin:$PATH
COPY package.json /usr/src/app/package.json
RUN npm install --silent
RUN npm install react-scripts#1.1.1 -g --silent
COPY . /usr/src/app
RUN npm run build
# production environment
FROM nginx:1.13.9-alpine
COPY --from=builder /usr/src/app/build /usr/share/nginx/html
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]
Not exactly a direct improvement of the author's code, but I was able to get a development environment working with very little code - and no direct dependency to node on my machine - like this:
docker-compose.yml
services:
node:
image: node:16
user: "node"
command: "npm start"
working_dir: /app
volumes:
- ./:/app
ports:
- 3000:3000
This way, you avoid creating docker images from a Dockerfile.
Usage is generally like this:
install dependencies before running: docker compose run node npm install
run development environment: docker compose up
install new dependencies: docker compose run node npm install [package name]
clean up docker instances created with compose run: docker compose rm
While using docker in development with create-react-app, i discovered that it is possible to override the webpackDevServer configuration by adding CHOKIDAR_USEPOLLING=1to your .env file. This will make the file watching work again. It even refreshes the browser page on the host! The only thing that i discovered is that it doesn't open up a webpage automatically.
I can also advise to add tty: true to your service to have your original console output back into your terminal. To remove the container name prefixes in the logs, you can run something like this after running docker-compose up -d:
docker-compose logs -f --tail=100 client | cut -f2 -d \"|\""

Here is a simple (pure docker) solution without local installation of runtime (e.g. node):
cd /tmp
docker run -it --rm -v "$PWD":/app -w /app node yarn create react-app my-app
sudo chown -R $USER:root my-app/
cd my-app
nano docker-compose.yml # see docker-compose.yml below
docker compose up -d
docker-compose.yml:
services:
node:
image: node:16-alpine
environment:
- CHOKIDAR_USEPOLLING=true
- FAST_REFRESH=true
working_dir: /app
ports:
- '3000:3000'
command: "yarn start"
volumes:
- './:/app'
open localhost:3000 in your browser. Hot reload should work out of the box.
