Vagrant Binding JayDay 2013
This document discusses using Vagrant and configuration management tools like Puppet and Chef to create lightweight reproducible development environments. It provides an overview of virtualization and tools like Vagrant, Puppet and Chef. It demonstrates how to use these tools to automate the creation of virtual machines and configure them. It also summarizes the Vagrant-Binding Java library that allows managing Vagrant environments programmatically.

- 7. By only usingVMs we can rebuild any customer system
- 8. For each newcustomer the best matching VM is copied. So no initial setup is needed!
- 9. Why not deployall linux 64bit customer installations on one server VM?
- 10. Because we copythe VMs on our Laptops when we travel to the Customer. And we only need the system for one Customer then.
- 11. So you havea virtualized Server for every Customer where all developers work on?
- 12. No! Only onedeveloper works on one VM. If a developer starts working for a customer he simply copies the VM of another developer or customer.

- 49. JUnit support @Rule public VagrantTestRuletestRule = new VagrantTestRule(createConfig()); public static VagrantConfiguration createConfig() { //Configure VM with MySQL-Server & static ip } @Test public void testJdbc() {...} create VM start VM run UnitTest destroy VM default JUnit annotation manage VM lifecycle use builder API for VM specification use the VM
