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" ]`

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

Make sure you have added these commands:

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

Use this one for maximum efficient output with no error:
FROM ubuntu

Install dependencies

RUN apt-get update &&
apt-get install -y curl &&
curl -sL https://deb.nodesource.com/setup_18.x | bash - &&
apt-get install -y nodejs &&
apt-get upgrade -y &&
apt-get clean &&
rm -rf /var/lib/apt/lists/*

Set working directory

WORKDIR /app

Copy application files

COPY . .

Install node dependencies

RUN npm install

Set the default command

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

Use this one for maximum efficient output with no error:

1-----------------------------------------------------------------------------
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" ]

   OR

2--------------------------------------------------
FROM node

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

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

This worked for me:

FROM ubuntu:latest

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

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

RUN node -v
RUN npm -v

COPY package.json package-lock.json ./

RUN npm install

COPY index.js .

EXPOSE 3000

CMD ["node", "index.js"]
