The official iojs docker image, made with love by the iojs community.
from iojs.org/faq.html
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.
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. In Example:
EXPOSE 8080Then 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
The iojs images come in three flavors, each designed for a specific use case.
<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.
<version>-onbuild:
This image makes building derivitative 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.
<version>-slim:
The default tag is based off of buildpack-deps.buildpack-deps is designed for the average user of docker who has many images on thier 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 total size of all of your docker images on your system. 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.
