Infrastructure

In the post Create A Test Environment with Terraform and KVM I created the first three virtual machines, now we configure a DNS server so name resolution works as expected. Since HCL Connections started to add Kubernetes to the stack, we need to use proper name resolution instead of just editing /etc/hosts. That’s a bit of an effort, but in the end it is way easier than checking several hosts if the hosts file is uptodate.

I create a lot of virtual machines during the week to test deployments, or try to digg into problems of deployments. In the past I used Vmware Workstation, Oracle VirtualBox or MS HyperV on my desktops, but I also used Vmware ESX. I tried to use Vagrant and Packer to prepare images and distribute them, but wasn’t satisfied at all.
