My container is exiting immediately upon running.
I am using Nestjs and Postgres.
Here is my Dockerfile:
FROM node:14.5.0 AS build
WORKDIR /src
RUN apt update && apt install python -y
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build
FROM node:14.5.0-alpine
ENV PORT=3000
WORKDIR /src
COPY --from=build /src/node_modules ./node_modules
COPY --from=build /src/dist ./dist
EXPOSE 3000
CMD [ "node", "dist/src/main.js"]
Here is the console output:
Thanks in Advance
So i solved it using Node version 13
I do not know whether the issue is in node 14 or if the Nest is not compatible with Node 14 yet.
For someone reading in future, here is the issue you can track :

I am working on containerization of Express app in TS. But not able to link node_modules installed outside the container. Volume is also mounted for development.But still getting error in editor(vscode) Cannot find module 'typeorm' or its corresponding type declarations., similar for all dependencies.
volumes:
- .:/usr/src/app
Dockerfile:
FROM node:16.8.0-alpine3.13 as builder
WORKDIR /usr/src/app
COPY package.json .
COPY transformPackage.js .
RUN ["node", "transformPackage"]
FROM node:16.8.0-alpine3.13
WORKDIR /usr/src/app
COPY --from=builder /usr/src/app/package-docker.json package.json
RUN apk update && apk upgrade
RUN npm install --quiet && mv node_modules ../ && ln -sf ../node_modules node_modules
COPY . .
EXPOSE 3080
ENV NODE_PATH=./dist
RUN npm run build
CMD ["npm", "start"]
I've one workaround where I can install dependencies locally, and then use those, but need another solution where we should install dependencies only in the container and not the outside.
Thanks in advance.
Your first code section implies you use docker-compose. Probably the build (of the Dockerfile) is also done there.
The point is that the volume mappings in the docker-compose are not available during build-phase in that same Docker-service.
I created a project using
npx create-strapi-app my-project --quickstart
created a Dockerfile:
FROM strapi/base
WORKDIR /srv/app
COPY ./package.json ./
COPY ./yarn.lock ./
RUN yarn install
COPY . .
ENV NODE_ENV production
RUN yarn build
EXPOSE 1337
CMD ["yarn", "start"]
Now i'm trying to build the Docker Image, but it stucks always when building the webpack.
When I manually start yarn build in the container, then i can see that it's stuck at 90% processing chunk assets.
My container has 4GB Ram and 2 cpus attached. I can see that its using 100% SSD Read the whole time.
Do you have any suggestions?
Strapi Docker Github issue
Try this :
FROM strapi/base
WORKDIR /srv/app
COPY ./package.json ./
COPY ./yarn.lock ./
COPY . .
RUN yarn install
ENV NODE_ENV production
RUN yarn build
EXPOSE 1337
CMD ["yarn", "start"]
I think COPY . . Before yarn install was the issue
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
Check out my article on this - https://askudhay.com/how-to-dockerize-an-angular-application, and please let me know if you still have any questions.
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.
This tutorial helped me figure out Docker Compose: https://wkrzywiec.medium.com/how-to-run-database-backend-and-frontend-in-a-single-click-with-docker-compose-4bcda66f6de
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 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?
I am trying to build a docker image for a node application that uses yarn to install dependencies. My Dockerfile looks like this:
FROM node:7
WORKDIR /app
COPY package.json /app
RUN yarn install
COPY . /app
CMD npm run develop
EXPOSE 8000
Every thing runs well when I run yarn install on my local machine but when I do a docker build, I get this error that blocks for ever.
**docker build -t rs .**

You should first run yarn install to generate a yarn lockfile (yarn.lock) before building the image. Then make sure to copy it along with the package.json. Your dockerfile should look like this :
FROM node:7
WORKDIR /app
COPY package.json /app
COPY yarn.lock /app
RUN yarn install
COPY . /app
CMD npm run develop
EXPOSE 8000
With this all dependencies should install successfully when building your image
Dockerfile
FROM node:6.9.5-alpine
RUN mkdir -p /code
WORKDIR /code
ADD . /code
RUN npm install -g -s --no-progress yarn && \
yarn && \
yarn run build && \
yarn cache clean
CMD [ "npm", "start" ]
EXPOSE 8080
docker-compose.yml
version: '2'
services:
sample-app:
image: sample-node-yarn-app
ports:
- "8080:8080"
Create docker image
docker build -t sample-node-app .
RUN
docker-compose up -d
You can simplify the above answers by using a predefined yarn docker image. We are assuming here this image is only for development purpose. For production mode, you should only consider the minimum binaries, such as node.
FROM gmolaire/yarn:1.22.4_12.18.3-alpine3.12
WORKDIR /usr/local/app
ADD . .
RUN yarn install && \
yarn build
EXPOSE 8080
CMD [ "yarn", "run", "develop" ]
