I want to change port in production build of node-adapter. I use port 3000 internally for different service, so I need to change Svelte app to have port 3001.
My Dockerfile:
# Container setup ---------
FROM node:16-alpine as build
RUN mkdir /appbuild
COPY . /appbuild
WORKDIR /appbuild
# clean install all dependencies
RUN npm ci
# remove potential security issues
RUN npm audit fix
RUN npm run build
# Container setup ---------
FROM node:16-alpine
WORKDIR /app
# copy dependency list
COPY --from=build /appbuild/package*.json ./
# clean install dependencies, no devDependencies, no prepare script
RUN npm ci --production --ignore-scripts
# remove potential security issues
RUN npm audit fix
# copy built SvelteKit app to /app
COPY --from=build /appbuild/build ./
CMD ["node", "./index.js"]
I found that if I start app like PORT=3001 node build from root (after calling npm run build) it works, but for dockerfile, CMD must be provided and PORT cannot be passed.
How to change default port to another one?
Have you tried using ENV?
ENV PORT=3001
CMD ["node", "./index.js"]
I am building my Dockerfile and I am inside my container and I don’t want to see all dev dependencies. I was using RUN yarn install --production but still I am seeing all dev dependencies. I need to change all prod builds to use RUN yarn install --production to build dependencies from lock files and not include dev dependencies.

My Angular app runs fine locally but I haven't figured out how to do the same with a Docker image. Outside of Docker, the UI runs on port 4200 with ng serve and the API serves data from 8080 with node server.js.
My Dockerfile is set up so it can get the Node server running and available on 8080, but the Angular UI won't run. I've tried several options but right now I have:
FROM node:14.17.3
COPY package*.json ./
EXPOSE 4200 8080
RUN npm install -g #angular/cli
RUN npm install --only=production
COPY . ./
RUN ng serve
CMD ["node", "server.js"]
It fails on ng serve with the error: The serve command requires to be run in an Angular project, but a project definition could not be found. I do have an angular.json file in the root. I'm not sure what I am missing. I read that ng serve shouldn't be used in this situation but the alternatives I've seen haven't made a difference.
Workspace:
EDIT 8/10/21: Based on the answers here and a bunch of research, this will display the UI with nginx:
FROM node:12.16.1-alpine as build
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm ci --only=production
COPY . .
# RUN npm install -g #angular/cli
# RUN npm run build --prod
FROM nginx:1.15.8-alpine
COPY --from=build /usr/src/app/dist /usr/share/nginx/html
# CMD ["node", "server.js"]
However, the npm run build step fails because ng is not found despite installing #angular/cli. I have to run this manually to build the dist folder. And I can't run node server.js alongside this. It seems I can only get the front end or back end, not both.
Use below command at the end to run ng serve with host 0.0.0.0 which means it listens to all interfaces.
CMD ["ng","serve","--host", "0.0.0.0"]
But I would suggest using ngInx.
Steps to follow:
Create a docker file under the root of your project, and add the below code. It takes care of: downloading dependencies, building angular project, and deploy it to ngInx server.
#Download Node Alpine image
FROM node:12.16.1-alpine As build
#Setup the working directory
WORKDIR /usr/src/ng-app
#Copy package.json
COPY package.json package-lock.json ./
#Install dependencies
RUN npm install
#Copy other files and folder to working directory
COPY . .
#Build Angular application in PROD mode
RUN npm run build
#Download NGINX Image
FROM nginx:1.15.8-alpine
#Copy built angular files to NGINX HTML folder
COPY --from=build /usr/src/ng-app/dist/pokemon-app/ /usr/share/nginx/html
Build docker image:
docker build -t my-ng-app .
Spinning the docker container with below command expose your app at port 80
docker run -dp 3000:80 my-ng-app

I figured out a solution that will run the full application. Most answers here focus on running the front end (the nginx suggestion was helpful). It seemed a Docker container could enable the UI or server but not both. I came across Docker Compose, which will run the front and back ends in separate images. My solution:
Dockerfile.ui
# Define node version
FROM node:12.16.1-alpine as build
# Define container directory
WORKDIR /usr/src/app
# Copy package*.json for npm install
COPY package*.json ./
# Run npm clean install, including dev dependencies for #angular-devkit
RUN npm ci
# Run npm install #angular/cli
RUN npm install -g #angular/cli
# Copy all files
COPY . .
# Run ng build through npm to create dist folder
RUN npm run build --prod
# Define nginx for front-end server
FROM nginx:1.15.8-alpine
# Copy dist from ng build to nginx html folder
COPY --from=build /usr/src/app/dist /usr/share/nginx/html
Dockerfile.server
# Define node version
FROM node:12.16.1-alpine
# Define container directory
WORKDIR /usr/src/app
# Copy package*.json for npm install
COPY package*.json ./
# Run npm clean install, prod dependencies only
RUN npm ci --only=production
# Copy all files
COPY . .
# Expose port 8080 for server
EXPOSE 8080
# Run "node server/run.js"
CMD ["node", "server/run.js"]
docker-compose.yml
version: '3'
services:
server:
build:
context: ./
dockerfile: Dockerfile.server
container_name: server
ports:
- 8080:8080
ui:
build:
context: ./
dockerfile: Dockerfile.ui
container_name: ui
ports:
- 4200:80
links:
- server
docker-compose up will build out an image for server and UI and deploy concurrently. I also resolved the ng not found errors by installing dev dependencies, particularly #angular-devkit/build-angular.

I think updating this line
COPY . ./
with
COPY . ./app
should solve that error. It appears that the node "volume" is in that folder.
Otherwise setting the workdir also seems like a solution:
FROM node:14
WORKDIR /usr/src/app
COPY package*.json ./
...

I used a docker file to execute package.json file but it stops at
GithubDatasetAPI#0.0.0 start /usr/src/app node ./bin/www
and doesn't go further or doesn't display error message.I updated to "\node ./bin/www" but doesn't work for me
Here is my DOCKERFILE
FROM node:8
# Create app directory
WORKDIR /usr/src/app
# Install app dependencies
# A wildcard is used to ensure both package.json AND package-lock.json are copied
# where available (npm#5+)
COPY package*.json ./
RUN npm install
# If you are building your code for production
# RUN npm install --only=production
# Bundle app source
COPY . .
EXPOSE 8082
CMD [ "npm", "start" ]
try to copy all the files not just package.json
COPY ./ ./
instead of
COPY package*.json ./
I am installing Express in a container.
I need the smallest development container and I am using a full container to install the dependencies
# container to install dendencies
FROM node:10 as installer
WORKDIR /src
COPY package.json package-lock.json ./
# install all dependencies
RUN npm install
# i need nodemon as global
RUN npm install -g nodemon
# working container
FROM node:10-alpine
RUN mkdir /src
WORKDIR /src
# copy everything (node_modules)
COPY --from=installer /src .
COPY . .
EXPOSE 3000
CMD ["nodemon", "start"]
I copied all the node_modules but how can I copy the global -g nodemon ?
How can I remove the "installer" container after the installation process?
