installing nodejs in dockerfile issue-CodePudding

I am trying to install nodejs in dockerfile with pyenv but I keep getting this error when I run it through my gitlab runner. I am trying to install version 16.12.0. Is there a better solution to this issue?

Dockerfile

#install npm
ENV NODE_VERSION=16.12.0
RUN apt install -y curl
RUN curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/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${NODE_VERSION}
ENV PATH="/root/.nvm/versions/node/v${NODE_VERSION}/bin/:${PATH}"
RUN node --version
RUN npm --version

output

In general you should avoid using version managers like nvm in Docker. You shouldn't need more than one version of a language interpreter at a time, and the version managers often require shell dotfile setup that's complicated to configure in Docker.

You don't say why you need Node. The easiest thing to do is to use the Docker Hub node image

FROM node:lts
# and none of what you show in the question

If you're using this to build the front end of your otherwise Python application, you can use a multi-stage build for this

FROM node:lts AS frontend
WORKDIR /frontend
COPY frontend/package*.json ./
RUN npm ci
COPY frontend/ ./
RUN npm build

FROM python:3.10
...
COPY --from=frontend /frontend/dist ./static/

If you really need Node in your otherwise Ubuntu-based image, the next easiest thing to do is just install it. The default Ubuntu nodejs package should work fine for most practical uses.

FROM ubuntu:20.04
RUN apt-get update \
 && DEBIAN_FRONTEND=noninteractive \
    apt-get --no-install-recomends --assume-yes \
      nodejs

If you really need it in a custom image, and it really needs to be a super specific version of Node, you should be able to just download Node and install it.

FROM ubuntu:20.04
RUN apt-get update \
 && DEBIAN_FRONTEND=noninteractive \
    apt-get --no-install-recomends --assume-yes \
      curl \
      xz-utils
ARG node_version=v16.14.2
RUN cd /opt \
 && curl -LO https://nodejs.org/dist/${node_version}/node-${node_version}-linux-x64.tar.xz \
 && tar xJf node-${node_version}-linux-x64.tar.xz \
 && rm node-${node_version}-linux-x64.tar.xz
ENV PATH=/opt/node-${node_version}-linux-x64/bin:${PATH}
