We now install the Node.js application and create a new Container image with name hello-node. It just uses the Windows version of the iojs:onbuild Docker image: FROM iojs:onbuildĪll further steps to add the Node.js code and run npm install is already in this Docker image. The Dockerfile for this example is quite simple. 'use strict' Ĭonsole.log('Hello World from', os.hostname()) "test": "echo \"Error: no test specified\" & exit 1"Īs a simple example we just print a message, wait five seconds and print another message and exit the Node.js application. "description": "Hello world from io.js in a Windows docker container", index.js - with the application source code.package.json - with the start command and optional dependencies.Now we create a simple Node.js application and create a Windows Docker image with it. Now create the Docker image for this Dockerfile with this command: docker build -t iojs:onbuild. This is my current Windows version of the onbuild Dockerfile that works with the current version of the Windows docker daemon. The current behavior is slightly different to Linux containers, but I found a workaround. On Windows this and the COPY commands seems to be a work in progress. It uses WORKDIR to set the current directory for all further commands. This is the Linux version of the Dockerfile: FROM iojs:3.1.0 You do not need to have Node.js installed on your host.Īgain I started with the official iojs:onbuild Dockerfile and ported it to Windows. This Dockerfile can be used to add your Node.js application into a new Docker image very easily. The official iojs Docker image has a nice second Dockerfile that uses the ONBUILD keyword. OK, we now have the latest io.js running in a Windows Docker container. You can check the Docker image by running the installed Node.js runtime and retrieve the iojs version PS C:\Users\vagrant> docker run -it iojs iojs -version You can check your available images with docker images The second command also tags the iojs:latest with the version number of io.js. Now you have your own iojs Docker image for Windows. Then build the Docker image with docker build -t iojs. To try it yourself, open up an editor and put these lines into a file Dockerfile and save it. RUN powershell -Command "wget -Uri -OutFile iojs.msi -UseBasicParsing" This is my Windows version of the Dockerfile: FROM windowsservercore I started with the official iojs Dockerfile and ported that to Windows commands. You can check that you are working with a Windows Docker daemon with the command docker version.Īs a first example I want to show how to create a Node.js Docker image for Windows. Now the Docker daemon should be up and running as well as a first Docker base image windowsservercore. This script will download and install the Docker daemon and a base image. Open a Powershell as an administrator and run these commands: wget -uri -OutFile C:\ContainerSetup.ps1 In the case you only have a vanilla Window 2016 TP3 machine without Docker installed, you can follow this Quick start guide. You either need a VM running in Azure with Windows 2016 TP3 or you try Windows 2016 TP3 locally in a VM. So everybody who is interested in Docker on Windows is now able to get a first impression of the current work. Last week Microsoft has released a technical preview of the upcoming Windows Server 2016 with a first running version of the Docker daemon for Windows.
