Jamf Distribution Server Instances

A Jamf Distribution Server (JDS) instance is a distribution point that is managed by Jamf Pro, similar to a computer or mobile device. It can be used to host packages, in-house apps, and in-house eBooks.

Before using a JDS instance, you must install it and configure it. JDS instances can be installed on Mac or Linux. When you install a JDS instance, it is enrolled with Jamf Pro. You can install as many instances as your organization requires.

By default, the first JDS instance you install is the root. The root instance is used by other instances as the authoritative source for all files. The root instance can also be used as the master distribution point. You can make a different instance the root at any time.

You can define parent-child relationships between non-root JDS instances, making selective file replication more manageable.

When you configure a JDS instance, you can do the following:

  • Make it the master distribution point.

  • Choose a parent JDS instance (non-root JDS instances only).

  • Enable certificate-based authentication.

  • Limit the rate at which the JDS instance downloads files.

  • Specify WebDAV accounts.

  • Choose whether to replicate specific files or the entire contents of the parent JDS instance
    (non-root JDS instances only).

You can also view the progress of file replication and view inventory information for each JDS instance.

To manage JDS instances in Jamf Pro, you need a valid SSL certificate on the Jamf Pro host server. (For more information, see SSL Certificate.)

Note: If you have upgraded from Jamf Pro 8.x, you must migrate the scripts and packages on your master distribution point before configuring JDS instances. (For more information, see the Migrating Packages and Scripts Knowledge Base article.)

Configuring a JDS Instance

  1. Log in to Jamf Pro.

  2. In the top-right corner of the page, click Settings images/download/thumbnails/16442406/Icon_Settings_Hover.png .

  3. Click Server Infrastructure.

  4. Click JDS Instances images/download/thumbnails/16442406/Icon_JDS_Instances.png .

  5. Click the JDS instance you want to configure.

  6. Click Edit.

  7. Use the General pane to configure basic settings for the JDS instance.

  8. Click the Distribution Point tab and configure distribution settings.

  9. Click Save.

Replicating Files to the Root JDS Instance

During replication, all files on the master distribution point are replicated to the root JDS instance. Then, files are replicated to child JDS instances from their non-root parent instances on check in with Jamf Pro. The files that are replicated to non-root JDS instances depend on whether each instance is configured to replicate specific files or the entire contents of their parent JDS instance.

  1. Open Jamf Admin and authenticate to the Jamf Pro server.

  2. In the sidebar, select the root JDS instance.

  3. Click Replicate.

Viewing the Progress of File Replication

  1. Log in to Jamf Pro.

  2. In the top-right corner of the page, click Settings images/download/thumbnails/16442406/Icon_Settings_Hover.png .

  3. Click Server Infrastructure.

  4. Click JDS Instances images/download/thumbnails/16442406/Icon_JDS_Instances.png .

  5. Click Grid View images/download/thumbnails/16442406/Icon_Grid_View.png at the top of the list.

The progress of file replication for each JDS instance is displayed. If your master distribution point is a JDS instance, it is marked with two asterisks (**). If your master distribution point is a different type of distribution point, the root instance is marked with a single asterisk (*).

Viewing Inventory Information for a JDS Instance

Jamf Pro displays the following inventory information for each JDS instance:

  • Whether or not it is the master distribution point

  • Whether or not it is the root instance

  • Hostname

  • URL

  • Reported IP address

  • jamfds binary version

  • Operating system

  • Operating system version

  • Total memory

  • Available memory
