To configure PowerShell DSC, you need to create a DSC configuration script and apply it to the target node(s). Here are the high-level steps to configure PowerShell DSC:
- Create a DSC configuration script:
Use the PowerShell ISE or any other text editor to create a DSC configuration script that defines the desired state of the target node(s). Here is an example of a basic DSC configuration script:
PowerShell
Configuration MyDSCConfiguration {
Node "TargetNode" {
# Define the resources that you want to configure
# For example, you can use the following to install IIS:
WindowsFeature IIS {
Ensure = "Present"
Name = "Web-Server"
}
}
}
- Compile the DSC configuration script:
After you have created the DSC configuration script, compile it using the Start-DscConfiguration
cmdlet. Here’s an example:
PowerShell
Start-DscConfiguration -Path .\MyDSCConfiguration -Wait -Verbose
This command starts the configuration process, applies the configuration to the target node(s), and waits for the process to complete.
- Verify the DSC configuration:
Once the DSC configuration has been applied, use the Get-DscConfiguration
cmdlet to verify that the desired configuration has been applied to the target node(s). Here’s an example:
PowerShell
Get-DscConfiguration
This command retrieves the current configuration of the target node(s) and displays it in the PowerShell console.
- Monitor and maintain the DSC configuration:
Finally, monitor the DSC configuration and make any necessary changes or updates using the PowerShell ISE or text editor. You can also use the Update-DscConfiguration
cmdlet to update the configuration on the target node(s) when changes are made. Here’s an example:
PowerShell
Update-DscConfiguration -Wait -Verbose
This command updates the configuration on the target node(s) with any changes that have been made to the DSC configuration script.
