Install node in Dockerfile?

Question

Answer 1

Get the node image and put it at the top of your dockerfile:

FROM node:[tag_name] AS [alias_name]

Verify the version by adding following code:

RUN echo "NODE Version:" && node --version
RUN echo "NPM Version:" && npm --version

Then add the following code every time you need to use nodejs in a container:

COPY --from=[alias_name] . .

From the codes above, replace the following with:

[tag_name] - the tag value of the node image you want to use. Visit https://hub.docker.com/_/node?tab=tags for the list of available tags.

[alias_name] - your preferred image name to use in your dockerfile.

Example:

FROM node:latest AS node_base

RUN echo "NODE Version:" && node --version
RUN echo "NPM Version:" && npm --version


FROM php:5.6-apache

COPY --from=node_base . .
