By far the most popular solution for managing SmartOS configuration is Opscode Chef. It is a very powerful tool with a very active community of users. Here you'll learn about the various ways in which you can utilize Chef to manage your SmartOS nodes.
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
knifeutility. This includes sending cookbooks to the Opscode Platform, bootstrapping new nodes with Knife Bootstrap Templates, and running the
chef-clientas 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 Joyent smartos_cookbooks Github Repo¶
Many of the tools and cookbooks referenced on this page can be found in the joyent/smartos_cookbooks Github repository.
For cookbooks and scripts to be used with SmartMachines/Zones, please refer to the joyent/smartmachine_cookbooks repo.
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.
We offer two version of the distribution: a plain tarball, and a pkgsrc
package you can install with
pkg_add or add to your own pkgsrc repo.
The package installs itself to
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 Opscode.com 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
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
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
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
benr@magnolia:~/git$ git clone https://github.com/joyent/smartos_cookbooks.git 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"
\~/.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
<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:

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:
- Fork the smartos_cookbooks Repository
- Modify the bootstrap script to match your web server IP's and URL scheme
- Create one or more Node Attribute files
- Review, modify, or add to the Cookbooks as you wish
- Copy the bootstrap script, fat client, cookbook tarball, node attributes to a web server
- 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 http://meme.com/chef/. 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 bootstrap-smartos.sh* -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
variable 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 SERVER_DEST= 220.127.116.11:/www/smartos/ benr@magnolia:~/git/smartos_cookbooks$ make tar cfz /tmp/smartos_cookbooks.tar.gz cookbooks scp /tmp/smartos_cookbooks.tar.gz 18.104.22.168:/www/smartos/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 192.168.100.2 192.168.100.3 ## Hosts in DC2: Allow from 10.0.10.0/23 10.0.100.0/24
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.
