Using Chef

Before we dig into the various components and procedures, lets briefly consider the various combinations of options available to you. These methods can be mixed-and-matched to fit your specific situation. Please consider the following:

  • Chef Client Installation. Options available include:
    • The illumos Ops Omnibus Spin: Discussed below, this is our binary distribution of Chef to simplify and speed installation
    • Install pkgsrc's Ruby, then install the Chef Gem: This is a more complex solution which takes more time and consume far more disk, but if wish to leverage pkgsrc in other ways, such as installing Nagios for example, it may be a viable option
  • Cookbook Distribution & Orchestration
    • Hosted Chef & Knife: In this case you would orchestrate using the knife utility. This includes sending cookbooks to the Opscode Platform, bootstrapping new nodes with Knife Bootstrap Templates, and running the chef-client as a daemon which executes on a regular schedule finding and applying changes to your cookbooks.
    • Chef Solo & Scripts: In this case you would create a custom bash bootstrap script, hosted on a web server accessible to the nodes, which would be responsible for installing Chef on the node, configuring it, and creating an SMF service to wrap chef-solo. The cookbooks would be stored on the web server as a tarball which would be downloaded on each chef-solo run which is initiated manually by restarting the Chef SMF service.

As I said, these options can be mixed and matched. For instance, if you opt to use Knife to bootstrap a node, you may use a bootstrap template which installs PKG-SRC and then Chef and its dependencies or you may opt for a simpler bootstrap template which uses the fat client. There are many possible combinations and it would be possible to explore all of them. Therefore, we will present some details here on some of the concepts and you can use them in whichever order is best for you.

The smartos_cookbooks Github Repo

Many of the tools and cookbooks referenced on this page can be found in the smartos_cookbooks Github repository.

For cookbooks and scripts to be used with SmartMachines/Zones, please refer to the smartmachine_cookbooks repo.

Installing Chef

The illumos Ops Omnibus Spin

To speed up deployment and minimize dependencies on nodes, illumos Operations produces a spin of the official Chef Omnibus build for Solaris.

Please note that this client distribution is not official or supported by either Chef, illumos, or Joyent.

Due to licensing changes, 13.7.6 is the last version that will be provided. This bundle has patched a bug in package handling.

To extract the tarball, run

tar zxf chef-13.7.16-1a.sunos.tar.gz -C /opt

Chef will be located in /opt/chef.

Installation via pkgsrc and gem

If you'd prefer to use the Chef gem, you can use pkgin install to install the Ruby and then gem install chef.

Managing SmartOS using the Opscode Platform (Hosted Chef) & Knife

Getting Started with Knife & The Opscode Platform

For clarity, we'll assume this is your first time using Chef. Install Chef on your local system as appropriate; see Chef Wiki: Installation for help.

Start by going to and signing up for a free Hosted Chef account. Once you've logged into your account, navigate to the Organizations page and download the "Knife Config" (knife.rb). Create a ~/.chef/~ directory and copy the knife.rb file you downloaded into it. When you created your account you should have received a client key and validation key; if you don't have them, generate a new validation key on your Organizations page and a generate a new client (user) key on your account change password page. When you have both keys, copy them into the /.chef/ directory.

benr@magnolia:~$ mkdir ~/.chef
benr@magnolia:~$ cp ~/Downloads/knife.rb ~/.chef/
benr@magnolia:~$ cp Downloads/*.pem ~/.chef

Next we need to download some cookbooks. Get a head start by pulling the smartos_cookbooks repository from Github. The cookbook root is smartos_cookbooks/cookbooks. You'll want to then update your Knife configuration to use this directory as your cookbook path, by modifying the cookbook_path line in ~/.chef/knife.rb.

benr@magnolia:~/git$ git clone
Cloning into 'smartos_cookbooks'...
remote: Counting objects: 91, done.
remote: Compressing objects: 100% (66/66), done.
remote: Total 91 (delta 6), reused 88 (delta 6)
Unpacking objects: 100% (91/91), done.

benr@magnolia:~/git$ cd smartos_cookbooks/cookbooks/
benr@magnolia:~/git/smartos_cookbooks/cookbooks$ ls
bart  logging  smartos  zabbix

benr@magnolia:~/git$ grep cookbook_path ~/.chef/knife.rb
cookbook_path            ["/home/benr/git/smartos_cookbooks/cookbooks"]

Now we're ready to start working with knife. You can upload the cookbooks you'd like to use.

benr@magnolia:~$ knife cookbook upload smartos bart
Uploading bart                [0.0.1]
Uploading smartos             [0.0.1]
Uploaded 2 cookbooks.

Bootstrap SmartOS Using Knife

Knife has the ability to "bootstrap" a node. This process consists of SSH'ing to the node and executing a bootstrap script which installs Chef as appropriate for the "distribution", then configures the client and starts it running. At the time of this writting there is no SmartOS bootstrap scripts provided by default with Chef, so we'll need to create our own. This is done by creating a .erb file for the "distribution" in \~/.chef/bootstrap/ and then specifying the distro name during boostrap with knife.

There are 2 Knife Bootstraps available for the SmartOS Global Zone, one using the flat client and another using PKG-SRC, which can be downloaded here: SmartOS GZ Knife Bootstraps on Github.

Once the bootstrap template is in place, we can use knife bootstrap <ip addr> to setup the node. We will pass 3 optional arguments: "-d smartos-fat" to specify the bootstrap template ("distribution"), "-r smartos" to specify which cookbooks should be in the initial cookbook run_list, and finally "-N hostname" to specify the name we wish to give to this node, which the smartos cookbook will also set as your hostname.

Here is example of what bootstrapping using the Fat Client looks like:

benr@magnolia:~$ knife bootstrap -d smartos-gz-fat -r smartos -N smartos20

Managing SmartOS using Chef Solo & A Web Server

Chef Solo provides a means of executing cookbooks without the need for a Chef server. This is ideal in both very small (where it's not worth the trouble) and very large (where a single server may be overwhelmed) deployments. The following is a description of the process of building a Chef Solo implementation similar to that used by Joyent Operations.

At a high level, the process will look like this:

  1. Fork the smartos_cookbooks Repository
  2. Modify the bootstrap script to match your web server IP's and URL scheme
  3. Create one or more Node Attribute files
  4. Review, modify, or add to the Cookbooks as you wish
  5. Copy the bootstrap script, fat client, cookbook tarball, node attributes to a web server
  6. Execute the bootstrap script on new clients

Your Web Server

With Solo we'll server all content to our nodes using standard HTTP rather than a Chef server. Therefore, you'll require a directory on a web server somewhere which can serve your files, we'll assume Remember that one of key advantages of using this method instead of Chef Server is because it is so easy to scale web servers, so please choose a capable machine for the task.

In your web directory you will host the following files:

[cuddletech:/www/smartos] benr$ ls -l
total 27436
-rw-r--r--   1 benr     other        13M Sep 18 10:08 Chef-fatclient-SmartOS-10.14.2.tar.bz2
-rwxr-xr-x   1 benr     other       1.3K Sep 21 01:17*
-rw-r--r--   1 benr     other       1.9K Sep 21 01:17 chef-solo.xml
-rw-r--r--   1 benr     other         41 Sep 21 01:17 smartos.json
-rw-r--r--   1 benr     other       234K Sep 21 01:17 smartos_cookbooks.tar.gz

All but the fatclient come directly from the smartos_cookbooks git repository. Clone the repository to your load system, then edit the SERVER_DEST variable in the Makefile to the host and path where your files will be scp'ed to. Once done, you can modify and commit changes to your local repo and send them all to the server by simply typing "make":

benr@magnolia:~/git/smartos_cookbooks$ head Makefile
# Makefile for SmartOS Deployment
TAR=            tar
DISTNAME=       smartos_cookbooks.tar.gz

benr@magnolia:~/git/smartos_cookbooks$ make
tar cfz /tmp/smartos_cookbooks.tar.gz cookbooks
scp /tmp/smartos_cookbooks.tar.gz 100%  234KB 233.5KB/s   00:00

Finally, you should lock down your Chef files if they contain sensitive information. The best method is to add ACL's to a .htaccess file in the directory your using. Here is an example:

Order Deny,Allow
Deny from all
## Lab Nodes:
Allow from
## Hosts in DC2:
Allow from

The Chef Solo Bootstrap Script

The bootstrap script is a BASH script which can be curl'ed and executed as a single line thus making node setup as easy and mistake proof as possible. This should not be confused with the earlier mentioned Knife Bootstrap scripts.
