Alpine environment for docker services
Full Description

Minimal Node.js Docker Images (18MB, or 6.7MB compressed)

Versions v7.1.0, v6.9.1, v4.6.2, v0.12.17 and v0.10.48 –
built on Alpine Linux.

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, 7, 7.1, 7.1.0 – 54.26 MB (npm 3.10.9)
    • 6, 6.9, 6.9.1 – 49.73 MB (npm 3.10.8)
    • 4, 4.6, 4.6.2 – 36.81 MB (npm 2.15.11)
    • 0.12, 0.12.17 – 32.71 MB (npm 2.15.11)
    • 0.10, 0.10.48 – 28.16 MB (npm 2.15.11)
  • Base install with node built as a static binary with no npm:
    • base, base-7, base-7.1, base-7.1.0 – 41.98 MB
    • base-6, base-6.9, base-6.9.1 – 38.17 MB
    • base-4, base-4.6, base-4.6.2 – 27.86 MB
    • base-0.12, base-0.12.17 – 24.07 MB
    • base-0.10, base-0.10.48 – 18.22 MB

Major io.js versions are tagged too.


$ docker run mhart/alpine-node node --version

$ docker run mhart/alpine-node npm --version

$ docker run mhart/alpine-node:6 node --version

$ docker run mhart/alpine-node:base node --version

$ docker run mhart/alpine-node:base-0.10 node --version

Example Dockerfile for your own Node.js project

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-6
# FROM mhart/alpine-node:6

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

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).
