In this article I want to show you the way for running your multi container solution on Docker. Docker Compose is a tool for defining and running multiple Docker containers using a single command. Wit
Today you will learn how we can package our static html Angular app in a Docker container running Nginx. By packaging our app in a Docker container we will benefit from the fact that we will have some
In this post I want to cover how you can setup a Docker development environment on Windows/Mac. As you might already know Docker requires a Linux kernel to run. Therefore we will always need a VM to
Since a while I have been using Virtualbox + vagrant to do web development based on Linux, Nginx and NodeJS. However I also still do Windows development occasionally. For that reason I needed a way
In the previous part of this series we had a look on building a bare Debian VM with the bare minimum packages installed to run a web server. In this part we will have a look on how we can improve our packer script with user variables and how to use the file and shell provisioner. User variablesVariables can be easily added to the packer script by adding following JSON. 1234567891011{ "variables": { "username": "root", "password": "r00tme", "memory": "1024", "cpus": "1", "database_name": "{{env `DB_NAME`}}" }, "builders": [{ // Left for brevity} Best practice is to put your variables as the first property in your JSON, before your builders. This way you have all the configurable values to your script quickly accessible. As you can see we define for each variable a default value, which will be used as the value when the user doesn’t provide one. For the “database_name” variable I used a special default. This default will be retrieved from your environment variables. You can set this kind of variable just as you would set any other variable from your command line/shell.
Large development teams are often coping with the “It works on my machine” syndrome. One solution to solve these kind of issues is by give each single developer the same VM, which is most preferably the same as your production server. So imagine your company is building a web application. The web application is hosted on a Debian server using Apache, MySQL and PHP. So considering these preconditions I will give you a simple example to get your machines scripted en fully provisioned. In this first part of these series we will zoom in on the packer.io builders. So let me first explain you what packer is by quoting some statements of their webpage. Packer is a tool for creating identical machine images for multiple platforms from a single source configurationModern, AutomatedPacker is easy to use and automates the creation of any type of machine image. It embraces modern configuration management by encouraging you to use automated scripts to install and configure the software within your Packer-made images. Packer brings machine images into the modern age, unlocking untapped potential and opening new opportunities. Works Great WithOut of the box Packer comes with support to build images for Amazon EC2, DigitalOcean, VirtualBox, and VMware. Support for more platforms is on the way, and anyone can add new platforms via plugins. In order to create an image for a specific platform packer uses builders. Since I don’t want to zoom in on creating your own builder plugin for your own platform and I don’t want you to have more cost to get up your VM I will use the VirtualBox builder in this example. VirtualBox is free to use, so if you don’t have it already installed on your machine please first install VirtualBox to continue with this example. VirtualBox will run on following OSes: Windows, Linux and Mac, so no matter what OS you’re on, you can continue reading.
In a previous blog post I explained to you how to install Windows 8 in a virtual machine in VirtualBox. In VirtualBox I used 1 gig of memory and 2 of my cores and it performed quite good. However in t
Since today you can download the pre-release of Windows 8 (Developer preview). Since testing this new stuff out can be risky, it is best you do it in a virtual machine. You can download it the develop
