See Node install instructions.

Use Node image

Use the node image from Docker hub.

This includes Yarn already.

  • Dockerfile 
      FROM node:12

Latest Node from APT

Use the ubuntu image from Docker hub.

APT already supports Node, but you’ll only get a stable version which will behind the latest versions. See the next section to get a newer version of Node.

  • Dockerfile 
      FROM ubuntu
    
  RUN apt update
  RUN apt install -q -y nodejs
    
  RUN npm install -g yarn

Node from Deb source

Similar to above, but instead of getting the Node version supported by APT (e.g. 10 or 12), you get a target version that you specify (like 14 or 16).

On the curl line, use setup_14.x or setup_16.x for example (using a literal letter x).

Based on Installation instructions in the Node docs, which covers Ubuntu and Debian. The docs don’t say that you need to run update after adding the souce.

  • Dockerfile 
      FROM ubuntu
    
  RUN apt update
  RUN apt install -q -y curl
    
  RUN curl -sL "https://deb.nodesource.com/setup_14.x" | bash -
  RUN apt update
  RUN apt -q -y install nodejs
    
  RUN npm install -g yarn

Yarn from APT

Set up a plain image then add Yarn to it using apt.

  • Dockerfile 
      FROM ubuntu

  ENV DEBIAN_FRONTEND=noninteractive

  RUN apt update

  RUN apt install -q -y \
      apt-utils \
      curl \
      gnupg

  RUN apt remove cmdtest && apt remove yarn
  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 install -q -y yarn

Notes:

  • DEBIAN_FRONTEND is set to avoid the flow to set region for tzdata.
  • It found I got errors consistently on apt update so switched to apt-get update.
  • Adding apt-utils is not neeeded, but prevents error when using debconf.
  • There is already an apt packaged called yarn which is unrelated to JavaScript, so be sure to remove it.
  • Install gnupg for apt-key to work on the curl line.
