Vagrant-Binding JUG Dortmund
This document discusses using Vagrant and Puppet to create lightweight reproducible development environments using virtual machines. It introduces Vagrant for automating VM creation and management. Puppet is used to configure VMs through scripts. The Vagrant-Binding API allows managing and configuring VMs from Java code. It provides builder APIs, JUnit integration, and access to Puppet modules. The goal is to simplify VM lifecycle management for testing and development.

- 9. Why notdeploy all linux 64bit customer installat ions on one server VM?
- 10. Because we copy the VMs on our Laptop s when we travel to the Custo mer. And we only need the system for one Customer then.
- 11. So you have a virtualized r Serve r for every Custome rk whe re all developers wo on?
- 12. No only onede veloper works on s one VM. If a developer start e workin g for a customer h simp ly copies the VM of another developer.
