I have an angular 17 project and I want to dockerize it. I already build my image and when I tried to run the container using docker run -dit --name <container name> <imagename> but the container exits immediately after that. When I run docker ps my container doesn't appear.
Dockerfile:
# Use node image as builder
FROM node:18.14 AS builder
# Set working directory in the container
WORKDIR /app
# Copy package.json and package-lock.json to the container
COPY package.json package-lock.json ./
# Install dependencies
RUN npm install
# Copy the rest of the application code
COPY . .
# Build the application
RUN npm run build --prod
# Use nginx image for serving the application
FROM nginx:latest
# Copy built application files from builder stage to nginx directory
COPY --from=builder /app/dist/project /usr/share/nginx/html
# Expose port 80 for nginx
EXPOSE 80
# Start nginx in foreground
CMD ["nginx", "-g", "daemon off;"]
And I noticed that my image cannot be analyzed in docker desktop as shown in this screenshot: Docker Desktop
As you mentioned in comment exec /docker-entrypoint.sh: exec format error is the real problem to solve.
Can you come up with a minimal, reproducible example? As an example, this is working locally for me
# Use node image as builder
FROM node:18.14 AS builder
# Set working directory in the container
WORKDIR /app
# (pretend to) Build the application
RUN echo "Hello world" > out.txt
# Use nginx image for serving the application
FROM nginx:latest
# Copy built application files from builder stage to nginx directory
COPY --from=builder /app/ /usr/share/nginx/html
It's likely related to processor architecture differences, see Docker Fails When Building on M1 Macs (exec /usr/local/bin/docker-entrypoint.sh: exec format error) and https://docs.docker.com/build/guide/multi-platform/
If you're building an image locally and running it elsewhere, this may well be the solution - https://stackoverflow.com/a/69636473/131391
If you're building and running locally, then I would first make sure you can simply run the mentioned base images before writing the Dockerfile. e.g. docker run nginx:latest
