Microservices – Legolizing Software Development IV
An automated development environment will save you. We explain how we set up Jenkins, Docker and Git to work seamlessly together.
Exploring Docker Security – Part 2: Container flaws
Now that we’ve understood the basics, this second part will cover the most relevant container threats, their possible impact as well as existent countermeasures. Beyond that, a short overview of the most important sources for container threats will be provided. I’m pretty sure you’re not counting on most of them. Want to know more?
MirageOS
Introduction MirageOS is a new and rising trend when it comes to talking about cloud computing. More and more services are being relocated into modern cloud infrastructures, due to a lot of advantages like i.e. reduced costs, maximum flexibility and high performance. Todays services normally depend on big virtual machines (like i.e. Ubuntu Xenial with…
Exploring Docker Security – Part 1: The whale’s anatomy
When it comes to Docker, most of us immediately start thinking of current trends like Microservices, DevOps, fast deployment, or scalability. Without a doubt, Docker seems to hit the road towards establishing itself as the de-facto standard for lightweight application containers, shipping not only with lots of features and tools, but also great usability. However, another important topic is neglected very…
More is always better: building a cluster with Pies
So you have written the uber-pro-web-application with a bazillion of active users. But your requests start to get out of hand and the Raspberry Pi under your desk can’t handle all the pressure on its own. Finally, the time for rapid expansion has come! If you have already containerized your application, the step towards clustering your…
More docker = more power? – Part 3: Setting up the loadbalancer
To benefit from using a loadbalancer we need several machines to distribute the traffic on, evidently. Thanks to Docker we simply run docker run -d -p 81:80 testwebsite:1 to get a second machine. This time the container port of the webserver is mapped to port 81. If you now visit <IP OF YOUR VM>:81 you…
More docker = more power? – Part 2: Setting up Nginx and Docker
This is Part 2 of a series of posts. You can find Part 1 here: https://blog.mi.hdm-stuttgart.de/index.php/2016/01/03/more-docker-more-power-part-1-setting-up-virtualbox/ In the first part of this series we have set up two VirtualBox machines. One functions as the load balancer and the other will house our services. As the next step we want to install docker on the service VM.…
More docker = more power? – Part 1: Setting up VirtualBox
This series of blogposts will focus on the effects on response times when performing different tasks running on a variable number of docker containers in a virtual machine. What will be the performance differences running a small or large number of containers on the same machine? These posts will function as a step-by-step tutorial, enabling…
Docker- dive into its foundations
Docker has gained a lot of attention over the past several years. But not only because of its cool logo or it being the top buzzword of managers, but also because of its useful features. We talked about Docker quite a bit without really understanding why it’s so great to use. So we decided to take a closer look on…
