Universal utilizes an idempotent configuration system to ensure repeatable deployments of instances of the platform. The same cmdlets that are used to call the REST API are used to configure the system. When they are called by the configuration system, they do not call the REST API and just return objects that are then used to configure Universal.
A typical configuration file is just a PS1 file.
New-PSUDashboard -Name 'Dashboard' -Path 'dashboard.ps1' -Framework 'UniversalDashboard:3.0.0'
Using an idempotent configuration system all enables the ability to source control the configuration files used to deploy Universal instances.
The configuration files for Universal define the state of the system. Rather than calling a Remove cmdlet to remove an item from the Universal system, you simply remove the New cmdlet call from the established configuration file.
For example, scripts are added to the system by adding a
New-PSUScript cmdlet call to the
If you had two scripts, you
scripts.ps1would look like this.
New-PSUScript -Name 'Script1.ps1' -Path 'Script1.ps1'New-PSUScript -Name 'Script2.ps1' -Path 'Script2.ps1'
Script2.ps1from the system, you would just remove the second line.
New-PSUScript -Name 'Script2.ps1' -Path 'Script2.ps1'
When calling the Universal REST API or by using the Universal admin console, the configuration files will be updated automatically.
For each type of entity that is managed within Universal there is a configuration file that will be stored within the
./universal folder. The
./universalfolder will be managed underneath the
RepositoryFolder that you define within your
By default, configuration files will automatically be reloaded when changed. This means that if you make a change to one of the files, Universal will read the file, synchronize to its local database and the platform will have the new setting you defined.
For example, if you wanted to disable telemetry collection, you could change the
./universal/settings.ps1file. The original settings file may look like this.
To reconfigure Universal to turn off telemetry collection, you would just remove the
-Telemetry switch parameter.
Universal would detect this change and reload internally.
You can disable the automatic reload of the system by specifying the
-DisableAutoReload switch on
Set-PSUSetting. Settings will only reload on restart of the system or when a Git synchronization takes place.
Universal provides the ability to automatically synchronization configuration files and other artifacts with a remote git repository. Changes made via the Universal REST API or admin console will result in git commits and then be pushed automatically to the remote. Additionally, changes made in the remote will be pulled and Universal will automatically reload settings internally.
To configure git synchronization, use the
GitPassword settings in the
appsettings.json file. You will need to restart Universal after making these changes.
To learn more about configuration settings, read the Settings page.
You can view the status of Git synchronization operations on the
Settings \ General page within the admin console. Git synchronizations take place one a minute.
