# Chef Solo Provisioner
|
|
|
|
Type: `chef-solo`
|
|
|
|
The Chef solo Packer provisioner installs and configures software on machines built
|
|
by Packer using [chef-solo](http://docs.opscode.com/chef_solo.html). Cookbooks
|
|
can be uploaded from your local machine to the remote machine or remote paths
|
|
can be used.
|
|
|
|
The provisioner will even install Chef onto your machine if it isn't already
|
|
installed, using the official Chef installers provided by Opscode.
|
|
|
|
## Basic Example
|
|
|
|
The example below is fully functional and expects cookbooks in the
|
|
"cookbooks" directory relative to your working directory.
|
|
|
|
```javascript
|
|
{
|
|
"type": "chef-solo",
|
|
"cookbook_paths": ["cookbooks"]
|
|
}
|
|
```
|
|
|
|
## Configuration Reference
|
|
|
|
The reference of available configuration options is listed below. No
|
|
configuration is actually required, but at least `run_list` is recommended.
|
|
|
|
* `config_template` (string) - Path to a template that will be used for
|
|
the Chef configuration file. By default Packer only sets configuration
|
|
it needs to match the settings set in the provisioner configuration. If
|
|
you need to set configurations that the Packer provisioner doesn't support,
|
|
then you should use a custom configuration template. See the dedicated
|
|
"Chef Configuration" section below for more details.
|
|
|
|
* `cookbook_paths` (array of strings) - This is an array of paths to
|
|
"cookbooks" directories on your local filesystem. These will be uploaded
|
|
to the remote machine in the directory specified by the `staging_directory`.
|
|
By default, this is empty.
|
|
|
|
* `data_bags_path` (string) - The path to the "data\_bags" directory on your local filesystem.
|
|
These will be uploaded to the remote machine in the directory specified by the
|
|
`staging_directory`. By default, this is empty.
|
|
|
|
* `encrypted_data_bag_secret_path` (string) - The path to the file containing
|
|
the secret for encrypted data bags. By default, this is empty, so no
|
|
secret will be available.
|
|
|
|
* `environments_path` (string) - The path to the "environments" directory on your local filesystem.
|
|
These will be uploaded to the remote machine in the directory specified by the
|
|
`staging_directory`. By default, this is empty.
|
|
|
|
* `execute_command` (string) - The command used to execute Chef. This has
|
|
various [configuration template variables](/docs/templates/configuration-templates.html)
|
|
available. See below for more information.
|
|
|
|
* `install_command` (string) - The command used to install Chef. This has
|
|
various [configuration template variables](/docs/templates/configuration-templates.html)
|
|
available. See below for more information.
|
|
|
|
* `json` (object) - An arbitrary mapping of JSON that will be available as
|
|
node attributes while running Chef.
|
|
|
|
* `prevent_sudo` (boolean) - By default, the configured commands that are
|
|
executed to install and run Chef are executed with `sudo`. If this is true,
|
|
then the sudo will be omitted.
|
|
|
|
* `remote_cookbook_paths` (array of strings) - A list of paths on the remote
|
|
machine where cookbooks will already exist. These may exist from a previous
|
|
provisioner or step. If specified, Chef will be configured to look for
|
|
cookbooks here. By default, this is empty.
|
|
|
|
* `roles_path` (string) - The path to the "roles" directory on your local filesystem.
|
|
These will be uploaded to the remote machine in the directory specified by the
|
|
`staging_directory`. By default, this is empty.
|
|
|
|
* `run_list` (array of strings) - The [run list](http://docs.opscode.com/essentials_node_object_run_lists.html)
|
|
for Chef. By default this is empty.
|
|
|
|
* `skip_install` (boolean) - If true, Chef will not automatically be installed
|
|
on the machine using the Opscode omnibus installers.
|
|
|
|
* `staging_directory` (string) - This is the directory where all the configuration
|
|
of Chef by Packer will be placed. By default this is "/tmp/packer-chef-solo".
|
|
This directory doesn't need to exist but must have proper permissions so that
|
|
the SSH user that Packer uses is able to create directories and write into
|
|
this folder. If the permissions are not correct, use a shell provisioner
|
|
prior to this to configure it properly.
|
|
|
|
## Chef Configuration
|
|
|
|
By default, Packer uses a simple Chef configuration file in order to set
|
|
the options specified for the provisioner. But Chef is a complex tool that
|
|
supports many configuration options. Packer allows you to specify a custom
|
|
configuration template if you'd like to set custom configurations.
|
|
|
|
The default value for the configuration template is:
|
|
|
|
```liquid
|
|
cookbook_path [{{.CookbookPaths}}]
|
|
```
|
|
|
|
This template is a [configuration template](/docs/templates/configuration-templates.html)
|
|
and has a set of variables available to use:
|
|
|
|
* `ChefEnvironment` - The current enabled environment. Only non-empty
|
|
if the environment path is set.
|
|
* `CookbookPaths` is the set of cookbook paths ready to embedded directly
|
|
into a Ruby array to configure Chef.
|
|
* `DataBagsPath` is the path to the data bags folder.
|
|
* `EncryptedDataBagSecretPath` - The path to the encrypted data bag secret
|
|
* `EnvironmentsPath` - The path to the environments folder.
|
|
* `RolesPath` - The path to the roles folder.
|
|
|
|
## Execute Command
|
|
|
|
By default, Packer uses the following command (broken across multiple lines
|
|
for readability) to execute Chef:
|
|
|
|
```liquid
|
|
{{if .Sudo}}sudo {{end}}chef-solo \
|
|
--no-color \
|
|
-c {{.ConfigPath}} \
|
|
-j {{.JsonPath}}
|
|
```
|
|
|
|
This command can be customized using the `execute_command` configuration.
|
|
As you can see from the default value above, the value of this configuration
|
|
can contain various template variables, defined below:
|
|
|
|
* `ConfigPath` - The path to the Chef configuration file.
|
|
file.
|
|
* `JsonPath` - The path to the JSON attributes file for the node.
|
|
* `Sudo` - A boolean of whether to `sudo` the command or not, depending on
|
|
the value of the `prevent_sudo` configuration.
|
|
|
|
## Install Command
|
|
|
|
By default, Packer uses the following command (broken across multiple lines
|
|
for readability) to install Chef. This command can be customized if you want
|
|
to install Chef in another way.
|
|
|
|
```text
|
|
curl -L https://www.opscode.com/chef/install.sh | \
|
|
{{if .Sudo}}sudo{{end}} bash
|
|
```
|
|
|
|
This command can be customized using the `install_command` configuration.
