The official Node.js docker image, made with love by the node community.
Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.
See: http://nodejs.org
FROM node:4-onbuild
# replace this with your application's default port
EXPOSE 8888
You can then build and run the Docker image:
$ docker build -t my-nodejs-app .
$ docker run -it --rm --name my-running-app my-nodejs-app
The image assumes that your application has a file named
package.json
listing its
dependencies and defining its start
script.
For many simple, single file projects, you may find it inconvenient to write a
complete Dockerfile
. In such cases, you can run a Node.js script by using the
Node.js Docker image directly:
$ docker run -it --rm --name my-running-script -v "$PWD":/usr/src/app -w
/usr/src/app node:4 node your-daemon-or-script.js
The node
images come in many flavors, each designed for a specific use case.
This is the defacto image. If you are unsure about what your needs are, you
probably want to use this one. It is designed to be used both as a throw away
container (mount your source code and start the container to start your app), as
well as the base to build other images off of. This tag is based off of
buildpack-deps
.
buildpack-deps
is designed for the average user of docker who has many images
on their system. It, by design, has a large number of extremely common Debian
packages. This reduces the number of packages that images that derive from it
need to install, thus reducing the overall size of all images on your system.
This image makes building derivative images easier. For most use cases, creating
a Dockerfile
in the base of your project directory with the line FROM node:onbuild
will be enough to create a stand-alone image for your project.
While the onbuild
variant is really useful for "getting off the ground
running" (zero to Dockerized in a short period of time), it's not recommended
for long-term usage within a project due to the lack of control over when the
ONBUILD
triggers fire (see also
docker/docker#5714
,
docker/docker#8240
,
docker/docker#11917
).
Once you've got a handle on how your project functions within Docker, you'll
probably want to adjust your Dockerfile
to inherit from a non-onbuild
variant and copy the commands from the onbuild
variant Dockerfile
(moving
the ONBUILD
lines to the end and removing the ONBUILD
keywords) into your
own file so that you have tighter control over them and more transparency for
yourself and others looking at your Dockerfile
as to what it does. This also
makes it easier to add additional requirements as time goes on (such as
installing more packages before performing the previously-ONBUILD
steps).
This onbuild
variant will only install npm packages according to the
package.json
and does not adhere to the npm-shrinkwrap.json
(see full
discussion in
nodejs/docker-node#65
.
This image does not contain the common packages contained in the default tag and
only contains the minimal packages needed to run node
. Unless you are working
in an environment where only the Node.js image will be deployed and you have
space constraints, we highly recommend using the default image of this
repository.

This image is officially supported on Docker version 1.9.1.
Support for older versions (down to 1.6) is provided on a best-effort basis.
