How can I install yarn on the docker environment? – Debian

Now, I am trying to create the environment for Ruby on rails on docker.
I read the documents and some blogs some people wrote and tried.
But I got errors and couldn’t go through with it.

It seems like that I have to install yarn in the docker environment but I don’t know if I did it in a right way or not.

If anyone knows anything, please tell me.

what I wrote so far is something like this.

Dockerfile

FROM ruby:3.0.2
RUN apt-get update -qq && apt-get install -y nodejs postgresql-client


RUN mkdir /docker-test2
WORKDIR /docker-test2
COPY Gemfile /docker-test2/Gemfile
COPY Gemfile.lock /docker-test2/Gemfile.lock
RUN bundle install
COPY . /docker-test2


# Add a script to be executed every time the container starts.
COPY entrypoint.sh /usr/bin/
RUN chmod +x /usr/bin/entrypoint.sh
ENTRYPOINT ["entrypoint.sh"]
EXPOSE 3000

# Start the main process.
CMD ["rails", "server", "-b", "0.0.0.0"]

docker-compose.yml

version: "3.9"
services:
  db:
    image: postgres
    volumes:
      - ./tmp/db:/var/lib/postgresql/data
    environment:
      POSTGRES_PASSWORD: password
  web:
    build: .
    command: bash -c "rm -f tmp/pids/server.pid && bundle exec rails s -p 3000 -b '0.0.0.0'"
    volumes:
      - .:/docker-test2
    ports:
      - "3000:3000"
    depends_on:
      - db

entrypoint.sh

#!/bin/bash
set -e

# Remove a potentially pre-existing server.pid for Rails.
rm -f /docker-test2/tmp/pids/server.pid

# Then exec the container's main process (what's set as CMD in the Dockerfile).
exec "$@"

when I tried docker-compose run the error says something like this.

I found someone saying that I have to install webpacker first so I tried something like this. docker-compose run web bundle exec rails webpacker:install and errors says

Yarn not installed. Please download and install Yarn from https://yarnpkg.com/lang/en/docs/install/ Exiting!

I thought I should install yarn in the image so I also tried docker run web sh and apt-get install yarn but nothing has changed.

I would really appreciate it if you help me.

Thank you.

    I added RUN yarn install in Dockerfile and it worked, I still have problem though.

    1. Replace line 2 of your Dockerfile with the following
    RUN curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add -
RUN echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list
RUN apt-get update -qq && apt-get install -y nodejs postgresql-client yarn

    1. docker-compose build

    2. docker-compose run --no-deps web rails webpacker:install
