What is io.js?

io.js is a JavaScript platform built on Chrome's V8 runtime. This project began as a fork of Joyent's Node.js™ and is compatible with the npm ecosystem.

Why? io.js aims to provide faster and predictable release cycles. It currently merges in the latest language, API and performance improvements to V8 while also updating libuv and other base libraries.

This project aims to continue development of io.js under an "open governance model" as opposed to corporate stewardship.

How to use this image

If you want to distribute your application on the docker registry, create a Dockerfile in the root of application directory:

FROM iojs:onbuild

# Expose the ports that your app uses. For example:
EXPOSE 8080

Then simply run:

$ docker build -t iojs-app
...
$ docker run --rm -it iojs-app

To run a single script, you can mount it in a volume under /usr/src/app. From the root of your application directory (assuming your script is named index.js):

$ docker run -v "$PWD":/usr/src/app -w /usr/src/app -it --rm iojs iojs index.js

Image Variants

The iojs images come in many flavors, each designed for a specific use case.

`iojs:<version>`

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.

`iojs:onbuild`

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 iojs: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).

`iojs:slim`

This image does not contain the common packages contained in the default tag and only contains the minimal packages needed to run iojs. Unless you are working in an environment where only the iojs image will be deployed and you have space constraints, we highly recommend using the default image of this repository.
