NOTE: This image is not official. See here for the official Node image.
An unofficial Node.js docker image, made with love by as-com.
What is Node.js?
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.
How to use this image
Dockerfile in your Node.js app project
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
We have assembled a Best Practices Guide for those using these images on a daily basis.
Run a single Node.js script
For many simple, single file projects, you may find it inconvenient to write a
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
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 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
Dockerfile in the base of your project directory with the line
node:onbuild will be enough to create a stand-alone image for your project.
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
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-
variant and copy the commands from 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 variant will only install npm packages according to the
package.json and does not adhere to the
npm-shrinkwrap.json (see full
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
Supported Docker versions
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.
Please see the Docker installation
documentation for details on how to
upgrade your Docker daemon.
