What is the best way to indicate a 'yes' response when running an npm install in a Dockerfile?

I am working with a Dockerfile that looks like this:

FROM node:latest

RUN npm install something && \
    npm install something && \
    npm install something 

I am looking for a way to automatically pass 'yes' as the response for all required 'yes/no' prompts during npm installation. Is there a method or workaround to achieve this?

Answer №1

To set up Angular without sharing usage statistics, I employed the following command:

RUN echo n | npm install -g --silent @angular/cli

For your setup, you may want to try using echo y instead.

Answer №2

If you're working on a Linux system, the yes command is your go-to for automation:

RUN yes | npm install something && \
    npm install something && \
    yes yes | npm install something

The first line above sends a continuous stream of "y" to the initial npm install command. Additionally, the yes command allows you to specify what it outputs. If you need to output "yes" instead of just "y", you can execute yes yes as demonstrated in the third example.
