Answer 1

I am using following Dockerfile to setup node version 8.10.0.

Here I have used NVM (Node Version Manager ), so we can choose which node version should be installed on that container. Please use absolute path of npm when installing node modules (eg: /root/.nvm/versions/node/v${NODE_VERSION}/bin/npm install leasot@latest -g)

   FROM ubuntu:18.04
   ENV NODE_VERSION=8.10.0
   RUN apt-get update && \
       apt-get install wget curl ca-certificates rsync -y
   RUN wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.2/install.sh | bash
   ENV NVM_DIR=/root/.nvm
   RUN . "$NVM_DIR/nvm.sh" && nvm install ${NODE_VERSION}
   RUN . "$NVM_DIR/nvm.sh" &&  nvm use v${NODE_VERSION}
   RUN . "$NVM_DIR/nvm.sh" && nvm alias default v${NODE_VERSION}
   RUN cp /root/.nvm/versions/node/v${NODE_VERSION}/bin/node /usr/bin/
   RUN cp /root/.nvm/versions/node/v${NODE_VERSION}/bin/npm /usr/bin/
   RUN /root/.nvm/versions/node/v${NODE_VERSION}/bin/npm install  leasot@latest -g

Note: This is a cropped Dockerfile.
