Installing nodejs 10 + npm on alpine linux - node.js

Question

I am using Alpine to build my Rails app and I am having some issues with some of its dependencies.
Right now, here's my Dockerfile:
FROM ruby:2.5.1-alpine
ENV BUNDLER_VERSION=2.0.2
RUN apk add --update --no-cache \
binutils-gold \
build-base \
curl \
file \
g++ \
gcc \
git \
less \
libstdc++ \
libffi-dev \
libc-dev \
linux-headers \
libxml2-dev \
libxslt-dev \
libgcrypt-dev \
make \
netcat-openbsd \
nodejs \
openssl \
pkgconfig \
postgresql-dev \
python \
tzdata \
yarn
RUN gem install bundler -v 2.0.2
RUN mkdir /myapp
WORKDIR /myapp
COPY Gemfile /myapp/Gemfile
COPY Gemfile.lock /myapp/Gemfile.lock
RUN bundle config build.nokogiri --use-system-libraries
RUN bundle check || bundle install
COPY . /myapp
COPY entrypoint.sh /usr/bin/
RUN chmod +x /usr/bin/entrypoint.sh
ENTRYPOINT ["entrypoint.sh"]
EXPOSE 80
CMD ["rails", "server", "-b", "0.0.0.0", "-p", "80"]
My entrypoint.sh file looks like this:
#!/bin/sh
bundle install
rake db:migrate
rake db:seed
npm install
set -e
rm -f /myapp/tmp/pids/server.pid
exec "$#"
When it comes to npm install, I have issues trying to install puppeteer#3.0.0 (can't use 3.1.0 because of another error).
Here's the error when installing 3.1.0:
/myapp # npm install puppeteer#3.1.0
> puppeteer#3.1.0 install /myapp/node_modules/puppeteer
> node install.js
/myapp/node_modules/puppeteer/install.js:175
} catch {
^

Based on the lack of success getting 3.1.0 installed here, I was informed to try 3.0.0
So when trying to install 3.0.0, the following happens:
/myapp # npm install puppeteer#3.0.0
> puppeteer#3.0.0 install /myapp/node_modules/puppeteer
> node install.js
(node:111) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): The "original" argument must be of type function

+ puppeteer#3.0.0
added 4 packages in 1.264s
According to this, the node version is old. Currently, I am running nodejs 8.9.3, as shown here:
/myapp # node -v
v8.9.3
I tried to install nodejs-current, but it seems like it uninstalled npm.
/myapp # apk add nodejs-current
fetch http://dl-cdn.alpinelinux.org/alpine/v3.7/main/x86_64/APKINDEX.tar.gz

/myapp # node -v
v9.2.1
/myapp # npm install puppeteer#3.0.0
/bin/sh: npm: not found
How can I upgrade my nodejs version without uninstalling npm? If I try to install npm again, the following error occurs:
/myapp # apk add npm
ERROR: unsatisfiable constraints:
npm (missing):

/myapp # apk add --update npm

Answer 1

Specify the required version for node like you did with ruby, FROM ruby:2.5.1-alpine , in the Dockerfile or docker-compose.yml file otherwise accordingly.
Check this link for the suitable version.

Answer 2

You need to use the update version of ruby which has the upgraded version of alpine kernel. For an e.g., you can use ruby:2.5.3-alpine3.9
FROM ruby:2.5.3-alpine3.9
ENV BUNDLER_VERSION=2.0.2
RUN apk add --update --no-cache \
binutils-gold \
build-base \
curl \
file \
g++ \
gcc \
git \
less \
libstdc++ \
libffi-dev \
libc-dev \
linux-headers \
libxml2-dev \
libxslt-dev \
libgcrypt-dev \
make \
netcat-openbsd \
nodejs \
npm \
openssl \
pkgconfig \
postgresql-dev \
python \
tzdata \
yarn
RUN gem install bundler -v 2.0.2
RUN mkdir /myapp
WORKDIR /myapp
COPY Gemfile /myapp/Gemfile
COPY Gemfile.lock /myapp/Gemfile.lock
RUN bundle config build.nokogiri --use-system-libraries
RUN bundle check || bundle install
and output of few commands
/ # npm -v
6.4.1
/ # node -v
v10.14.2
/ # cat /etc/issue
