Python error when trying to deploy a nuxt app to docker.

[CareTiger]

Hi Captain
I am getting a weird error deploying a node app to Docker. here is my Dockerfile

# ---- Base Node ----
FROM node:18.16.1-bullseye-slim

RUN apt update

WORKDIR /src

COPY ./package.json ./

# Build application
RUN npm install && npm cache clean --force

COPY ./ /src/app/

# Use non-root user - NOT WORKING
# RUN chown -R node:node /src/app
# USER node

# Start the app
CMD [ "npm", "run", "dev", "--host", "0.0.0.0", "--port", "3000" ]

and here is part of the error

I don't know what the error is caused by, but here's some tips:

• You need to copy package.json and package-lock.json
• If you want to run as node user, don't manually chown, but do it with COPY command
• put node user before run and workdir commands and they'll have proper permissions
• there is no need to apt update since you aren't installing/upgrading anything
• you didn't change your workdir to the directory with your source code in it

Here's a fixed Dockerfile:

FROM node:18.16.1-bullseye-slim

USER node

WORKDIR /src

COPY --chown=node:node ./package*.json ./

RUN npm install && npm cache clean --force

WORKDIR /src/app

COPY --chown=node:node . .

CMD [ "npm", "run", "dev", "--host", "0.0.0.0", "--port", "3000" ]

I didn't test that, but see how it works.
