Dockerfile

FROM ubuntu

RUN apt-get update
RUN apt-get install -y curl
RUN curl -sL https://deb.nodesource.com/setup_18.x | bash -
RUN apt-get upgrade -y
RUN apt-get install -y nodejs

COPY package.json package.json
COPY package-lock.json package-lock.json
COPY main.js main.js

RUN npm install

ENTRYPOINT [ "node", "main.js" ]

while running above code in root directory, npm install will throw an error.

To solve this we can change the work directory:
e.g WORKDIR /usr/app

we can put this command before COPY commands
and it works fine
@piyushgarg-dev

Doing this also works fine, just perform the upgrade before install, and install the nodejs image:

`FROM ubuntu

RUN apt-get update
RUN apt-get install -y curl
RUN apt-get upgrade -y

RUN curl -sL https://deb.nodesource.com/setup_18.x | bash -
RUN apt-get install -y nodejs

COPY package.json package.json
COPY package-lock.json package-lock.json
COPY index.js index.js

RUN npm install
ENTRYPOINT [ "node","index.js" ]`
