A simple example for a Chef-managed Java developer VM, based on the linux-developer-vm template.
The Java Developer VM is based on Ubuntu 16.04 and includes:
- ChefDK - for managing / installing this developer VM
- Oracle JDK - obviously we need Java, in Oracle flavor please
- Maven - a build and dependency management system for Java
- Eclipse - the popular Java IDE
Other tweaks and settings worth mentioning:
- makes sure the
JAVA_HOME
environment variable is set properly - places a
README.md
file on the Desktop to guide first time users after they logged in to the VM - symlinks
update-vm.sh
to/usr/local/bin/update-vm
so it's in the$PATH
and can be used for updating the VM from the inside (see below)
The latest version of this developer VM can be downloaded as a VM image from here:
After downloading the .ova file you can import it into VirtualBox via File -> Import Appliance...
.
Once imported, you can simply start the VM and log in:
- username: "vagrant"
- password: "vagrant"
From then on just open a terminal and you will have all of the tools available (see "What's included?").
You can run these commands from anywhere inside the developer VM:
update-vm
- update the VM by applying the Chef recipes from the locally checked out repo at~/vm-setup
update-vm --pull
- same as above, but update repo before by pulling the latest changesupdate-vm --verify-only
- don't update the VM, only run the Serverspec testsupdate-vm --provision-only
- don't run the Serverspec tests, only update the vm
The VM ships with a full US
keyboard layout and en_US.UTF-8
locale by default.
To change the keyboard layout to your preferred language use System Settings... -> Text Entry
in the VM.
If you have a totally different keymap (e.g. on a MacBook) you can always reconfigure it:
sudo dpkg-reconfigure keyboard-configuration
If want to reconfigure the locale:
sudo dpkg-reconfigure locales
You only need VirtualBox and Vagrant installed.
All other requirements, including with ChefDK will be installed inside the Vagrant VM during provisioning, i.e. you don't need them installed on your host machine.
Bring up the developer VM:
$ vagrant up
This will take a while, as it will do quite a few things inside the VM:
- Download and install ChefDK
- Copy the current directory into the VM (will be placed in
~/vm-setup
) - Install cookbook dependencies via Berkshelf to
~/vm-setup/cookbooks/vm/cookbooks
- Trigger a Chef-Zero run to apply the
~/vm-setup/cookbooks/vm/recipes
to the VM (see "What's included?") - Verify the installation using a set of Serverspec tests
Watch the vagrant output on the console for seeing progress. At the end you should see all tests passing:
...
==> default: vm::base
==> default: places a README on the Desktop
==> default:
==> default: vm::eclipse
==> default: installs Eclipse Mars (4.5.0)
==> default:
==> default: vm::java
==> default: installs Oracle Java 8 update 31
==> default: sets JAVA_HOME correctly
==> default:
==> default: vm::maven
==> default: installs Maven 3.1.1
==> default:
==> default: update-vm.sh
==> default: installs chefdk 1.3.32
==> default: symlinks the update-vm script to /usr/local/bin/
==> default:
==> default: Finished in 0.43059 seconds (files took 0.79075 seconds to load)
==> default: 7 examples, 0 failures
If these are passing as expected, you can continue developing on the Chef recipes within this repo. Please don't forget to add a test for each new feature you add (see "Contributing")
Whenever you feel like distributing a fat VM image rather than a Vagrantfile, you can package / export it as a VirtualBox image. This might be useful for distributing the initial version of the developer VM to your dev team, or simply for preserving checkpoint releases as a binary images.
Let's start from a clean state:
$ vagrant destroy -f
$ vagrant up
This will provision the VM as usual. Once the provisioning succeeded, we will do a few cleanup steps before packaging the VM.
First, unmount the /vagrant shared folder:
$ vagrant ssh -c "sudo umount /vagrant -f"
Finally, shutdown the VM, remove the sharedfolder, and export the VM as an .ova file:
$ vagrant halt
$ VBoxManage sharedfolder remove "Java Developer VM" --name "vagrant"
$ VBoxManage modifyvm "Java Developer VM" --name "Java Developer VM v0.1.0"
$ VBoxManage export "Java Developer VM v0.1.0" --output "java-developer-vm-v0.1.0.ova" --options manifest,nomacs
Don't forget to throw away the VM when you are done:
$ vagrant destroy -f

- Create a named feature branch (like
feature/add-xyz
) - Implement your changes, add tests
- Commit and push
- Submit a Pull Request via Github
