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. To do that enter the following commands in the bash:
$ wget -qO- https://get.docker.com/ | sh $ sudo gpasswd -a <username> docker $ newgrp docker
This downloads and installs Docker, adds your user to the docker user group and logs you into this new group to allow you to create and run containers.
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 everyone to reproduce our studies.
In production one of the most scaled services are webservers. Therefore, we want to focus on stress testing a self hosted website that is being load balanced and running in a varying number of Docker containers.
