In most of my environments I reach in short time the requirement to have some kind of automation server. How cool would it be, to start this server as part of my local Virtual Development Server? And what if the result will be usable for a lot of other use cases too?
For extensive testing of Database Migration I need an environment with Liquibase and an Oracle Database. So I have built this Virtual Development Environment which can be started, stopped, removed and rebuilt in seconds.
In my series about Modern Infrastructure for your Virtual Development Server I will now start my Server with Vagrant in VirtualBox on Windows. Again I will use Jenkins as example for this. See how this works.
As I create my Virtual Development Servers I asked myself how can I easily test, that it is working? As I put now my servers into containers via docker-compose I searched for a test framework, which supports this out of the box. I heard a lot about TestContainers in the past and again at Javaland 2022 conference last week, so I want to test now, if this will help me.
In my series about Modern Infrastructure for your Virtual Development Server I will now start with the easiest case for me. I will run a Server on a Docker Desktop on Windows. As I need CI for all of my projects I will use Jenkins as example for this. See how this works.
After my 2016 series about my Virtual Development Server I have learned a lot. It’s time for a major overhaul with new technologies. It should be a lot more flexible and usable for development and course environments. See how I will restart!
We now try to automate the build of all needed images as soon as Oracle GitHub Sources changed or we need to build our Vagrant VirtualBox again from scratch.
For automation of all of my processes I need Jenkins in my development server. First I had installed Jenkins as Docker container via Vagrant Docker provider. But with this architecture it was very complicated to create docker images and run Docker containers on the Docker host, in this case my Vagrant Virtualbox. So for simplification I have decided to install Jenkins with the provisioning of the Vagrant Virtualbox via a shell provider in my Vagrantfile.
For later creation of containers as needed in the deployment process we have first to build docker images whenever we do not find suitable one in docker hub.
As I want later build Oracle docker images, some of this need a swapfile. Per default my used Vagrantbox does not have one, so later steps will fail.
As I want later build docker images and run docker containers I have to provide enough ram and disk space for this. Per default the Vagrantboxes have vmdk disks, these have a static size and are to small for my purposes.
As I want to decouple my development server from my computer as much as possible I want to create first a virtual machine with linux.
For long time I had the idea to create a virtual development server for testing some ideas and play with some new and old technologies.
