But containerization technologies like Docker, as much as they are cost effective in terms of memory and processor power, have a learning curve which while not too steep, do require a good chunk of time to be spent on learning. That’s why older virtualization techniques like VirtualBox are still being used to create environments for development and QA teams. And yes, they are quite effective!
This short tutorial will show you how to setup one of the little intricacies when developing in VirtualBox, namely being able to store and edit your code in the host machine, while running it inside the guest OS. Will be using CentOS 7 as a guest, while the host is not of any importance.
I will also show you how to make the VirtualBox guest accessible to the host via TCP.

No Samba/NFS tweaks are necessary on both the host and docker box. No hassle with Docker namespaces is also needed.
When doing devops work one of the many responsibilities you might have is creation of various installation or deployment scripts. They can be created in any scripting language, starting from the standard bash script to various server side languages (Perl, Python, PHP, etc…). For this example we are going to tackle a specific problem whenRead more about Wait for user input a period of time and continue with script execution if none is supplied[…]
Here in Macedonia we have a saying (rough translation): The cure is cheap, but you have to know it.

When you manage your own server there is this problem of finding a simple tool which would help you figure out where your network bandwidth is going. Especially if you are a developer or you have no training in server administration, once you enter this uncharted territory, this task which looks naive often turns out toRead more about Installing & using darkstat on CentOS 6.x[…]
