Munki Setup

22 Apr

If you haven’t yet used Munki its an excellent open source tool for software/profile deployment

Below is quick guide on how to get up and running on Yosemite Server, full credit to the awesome Github community and OSXDominion along with my own notes 🙂

 

Setting Up Munki With OS X Yosemite Server

There are many ways to set up Munki, since it’s just a webserver. TheDemonstration Setup is a great way to get started, but doesn’t list the steps for setting up OS X Server. A lot of new Munki admins (or generally new Munki admins) may have an OS X Server they have access to, but not other web servers, so a guide to getting started with the latest version of OS X Server (as of writing time, that’s Server 4, on Mac OS 10.10.2 Yosemite) may be helpful.

This is all assuming you’ve got Server.app set up and running.

If the Websites service in Server.app is running, turn it off first.

The first steps are to create the Munki repo in the location that Server 4 uses to store website data:
mkdir /Library/Server/Web/Data/Sites/Default/repo
mkdir /Library/Server/Web/Data/Sites/Default/repo/catalogs
mkdir /Library/Server/Web/Data/Sites/Default/repo/pkgs
mkdir /Library/Server/Web/Data/Sites/Default/repo/pkgsinfo
mkdir /Library/Server/Web/Data/Sites/Default/repo/manifests

Change permissions to make sure it’s accessible:
chmod -R a+rX /Library/Server/Web/Data/Sites/Default/repo

In the Server.app Websites pane, edit the “Server Website” (port 80) settings:
Next to “Redirects”, click “Edit…”, and remove the only redirect (which automatically redirects port 80 to port 443 traffic). It should look like this:

Next, click “Edit Advanced Settings” and check the box for “Allow folder listing” (just for now – it’s easier to visually test this way):

Turn the Websites service on.

Open up Safari, navigate to:
http://localhost/repo/

You should see a page like this:

If you can get to this point, you’ve done the website setup work. Now you can go to the next section:
https://github.com/munki/munki/wiki/Demonstration-Setup#populating-the-repo

Once you’ve populated the repo, you can set up a new manifest called “test_munki_client”. Follow the instructions exactly:
https://github.com/munki/munki/wiki/Demonstration-Setup#creating-a-client-manifest

Go through the Client Configuration section:
https://github.com/munki/munki/wiki/Demonstration-Setup#munki-client-configuration
Here, you need to do two things on your OS X client.

If you are testing this on the OS X Server itself (i.e. you are only using one machine total), do this:
sudo defaults write /Library/Preferences/ManagedInstalls SoftwareRepoURL "http://localhost/repo"
sudo defaults write /Library/Preferences/ManagedInstalls ClientIdentifier "test_munki_client"

If you are testing Munki on a different client machine from the server, do this:
sudo defaults write /Library/Preferences/ManagedInstalls SoftwareRepoURL "http://ip_or_domain_name_of_server/repo"
sudo defaults write /Library/Preferences/ManagedInstalls ClientIdentifier "test_munki_client"

And then finally you can check to see if Munki behaves as you’d expect:
sudo /usr/local/munki/managedsoftwareupdate -vv

Populating the repo

We now have a working Munki repo – but it’s completely empty and not useful at all. So let’s start to populate the repo.

We’re going to use some tools distributed with munki to import packages into our new Munki repo. Download the current munki installation package at https://github.com/munki/munki/releases/latest.

Install the Munki tools by mounting the disk image and double-clicking the Installer package and installing like any other package. A restart is required after installation.

The tools you’ll use as an administrator are available from the command-line, and are installed in /usr/local/munki. This location is not in the standard search path, so you’ll need to either add this directory to your search paths, or be sure to type the full path when invoking these tools.

The tool we will use to import packages into the munki repo is called munkiimport. We need to configure it before we can use it – telling it where to find our repo, among other things.

bash-3.2$ /usr/local/munki/munkiimport –configure
Path to munki repo (example: /Volumes/repo): /Users/Shared/munki_repo
Repo fileshare URL (example: afp://munki.example.com/repo):
pkginfo extension (Example: .plist):
pkginfo editor (examples: /usr/bin/vi or TextMate.app): TextMate.app
Default catalog to use (example: testing): testing
We are first asked for the path to the Munki repo, and since we set one up at /Users/Shared/munki_repo, that’s what we enter.

Next, we are asked for a repo fileshare URL. This is used when the repo is hosted on a remote file server, and this would typically be an afp:// or smb:// URL specifying the share. Since we’re hosting the repo on the local machine, we’ll leave this blank.

We are then asked to specify an extension to append to the name of pkginfo files. Some admins prefer “.plist”, some prefer “.pkginfo”. Personally, I just leave it blank – Munki doesn’t care.

Next, you are asked for an editor to use for the pkginfo files. If you like command-line editors, you can specify /usr/bin/vi or /usr/bin/emacs for example. If you, like me, prefer GUI text editors, you can specify a GUI text editor application by name (but be sure to include the “.app” extension). I picked TextMate.app, but you could choose TextWrangler.app, BBEdit.app, or even TextEdit.app.

Finally, you are asked for the default catalog new packages/pkginfo should be added to. We’ll use a “testing” catalog for this.
