# Basic Usage of Provisioners
|
|
|
|
While Vagrant offers multiple options for how you are able to provision
|
|
your machine, there is a standard usage pattern as well as some important
|
|
points common to all provisioners that are important to know.
|
|
|
|
## Configuration
|
|
|
|
First, every provisioner is configured within your [Vagrantfile](/v2/vagrantfile/index.html)
|
|
using the `config.vm.provision` method call. For example, the Vagrantfile
|
|
below enables shell provisioning:
|
|
|
|
```ruby
|
|
Vagrant.configure("2") do |config|
|
|
# ... other configuration
|
|
|
|
config.vm.provision :shell, :inline => "echo hello"
|
|
end
|
|
```
|
|
|
|
Every provisioner has an identifier, such as `:shell`, used as the first
|
|
parameter to the provisioning configuration. Following that is basic key/value
|
|
for configuring that specific provisioner. Instead of basic key/value, you
|
|
can also use a Ruby block for a syntax that is more like variable assignment.
|
|
The following is effectively the same as the prior example:
|
|
|
|
```ruby
|
|
Vagrant.configure("2") do |config|
|
|
# ... other configuration
|
|
|
|
config.vm.provision :shell do |s|
|
|
s.inline = "echo hello"
|
|
end
|
|
end
|
|
```
|
|
|
|
The benefit of the block-based syntax is that with more than a couple options
|
|
it can greatly improve readability. Additionally, some provisioners, like
|
|
the Chef provisioner, have special methods that can be called within that
|
|
block to ease configuration that can't be done with the key/value approach.
|
|
|
|
## Multiple Provisioners
|
|
|
|
Multiple `config.vm.provision` methods can be used to define multiple
|
|
provisioners. These provisioners will be run in the order they're defined.
|
|
This is useful for a variety of reasons, but most commonly it is used so
|
|
that a shell script can bootstrap some of the system so that another provisioner
|
|
can take over later.
|
|
|
|
## Running Provisioners
|
|
|
|
Provisioners are run in three cases: `vagrant up`, `vagrant reload`, and
|
|
`vagrant provision`.
|
|
|
|
A `--no-provision` flag can be passed to `up` and `reload` if you don't
|
|
want to run provisioners.
|
|
|
|
The `--provision-with` flag can be used if you only want to run a
|
|
specific provisioner if you have multiple provisioners specified. For
|
|
example, if you have a shell and Puppet provisioner and only want to
|
|
run the shell one, you can do `vagrant provision --provision-with shell`.
