3- Manage vmr environment


A vmr environment consist of a directory and a template file call Vagrantfile.
A vmr object contains information to create and modify an vmr environment. Once the environment created and initialized the vmr object became optional and only the working directory and the Vagrantfile are the managers.

Create a vmr environment

Create a vmr object

vmrCreate() function create a vmr object using several arguments:
* name : the box name (from vmrList())
* provider: the provider name (from vmrList())
* version: (optional by default latest version is use)
* provider.options: specific provider options (vignette n°5)

Load a vmr object

Set the working directory to a vmr environment who was already initialized.

Initialize a vmr environment

Initialize a vmr environment will create a Vagrantfile template into the working directory and download the box associated.

The box download can be long depending of the box size and network bandwide. The box is save in vagrant environment (“~/.vagrant.d/”).

vmr_env # created or loaded object
# force.vagrantfile will override existing Vagrantfile template
vmr_env <- vmrInitEnv(vmr_env, force.vagrantfile=TRUE)

Clean a vmr environment

To remove any file created, boxes downloaded and provider instance run this commands:

Add options to vmr environment

Several functions need and can modify a vmr object to add options to the environment.
vmrInitEnv() have to be recall at vmr object modification.

Upgrade environment

It’s possible to upgrade an environment to use the latest box version.

Shared files

To share a host directory to the guest.

Manipulate a vmr environment

This functions manage the environment instance.
They have to be call in vmr environment (working directory), with no arguments.

# Get environment status
# Start a provider instance
# Save state and stop provider instance
# Resume a saved provider instance
# Stop a provider instance
# Remove a provider instance


Manage provider instance with snapshot.
