What is Node.js?
Node.js applications are designed to maximize throughput and efficiency, using non-blocking I/O and asynchronous events. Node.js applications run single-threaded, although Node.js uses multiple threads for file and network events. Node.js is commonly used for real-time applications due to its asynchronous nature.
How to use this image
Dockerfile in your Node.js app project
FROM node:0.10-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
Run a single Node.js 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/myapp -w /usr/src/myapp node:0.10 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 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.
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 image will be deployed and you have space constraints, we highly recommend using the default image of this repository.
