Versions v6.4.0, v5.12.0, v4.5.0, v0.12.15, v0.10.46, and io.js – built on Alpine Linux.
NB: All images were recently updated to Alpine 3.4 –
there shouldn't be any breaking changes unless you rely on other apk packages. php has been
renamed to php5, cron to crond and most ruby- pkgs have been removed in favor of gem
All versions use the one mhart/alpine-node repository,
but each version aligns with the following tags (ie, mhart/alpine-node:<tag>). The sizes are for the
unpacked images as reported by Docker – compressed sizes are about 1/3 of these:
- Full install built with npm:
latest,6,6.4,6.4.0– 48.03 MB (npm 3.10.6)5,5.12,5.12.0– 37.63 MB (npm 3.10.3)4,4.5,4.5.0– 36.84 MB (npm 2.15.10)0.12,0.12.15– 32.8 MB (npm 2.15.9)0.10,0.10.46– 28.25 MB (npm 2.15.9)
- Base install with node built as a static binary with no npm:

Major io.js versions are tagged too.

If you don't have any native dependencies, ie only depend on pure-JS npm
modules, then my suggestion is to run npm install locally before running
docker build (and make sure node_modules isn't in your .dockerignore) –
then you don't need an npm install step in your Dockerfile and you don't need
npm installed in your Docker image – so you can use one of the smaller
base* images.
FROM mhart/alpine-node:base
# FROM mhart/alpine-node:base-0.10
# FROM mhart/alpine-node
WORKDIR /src
ADD . .
# If you have native dependencies, you'll need extra tools
# RUN apk add --no-cache make gcc g++ python
# If you need npm, don't use a base tag
# RUN npm install
EXPOSE 3000
CMD ["node", "index.js"]
As Alpine Linux uses musl, you may run into some issues with environments expecting glibc-like behavior – especially if you try to use binaries compiled with glibc. You should recompile these binaries to use musl (compiling on Alpine is probably the easiest way to do this).
