PowerShell - Desired State Configuration
What is DSC
management platform in Windows PowerShell that
enables deploying and managing configuration data for
software services and managing the environment in which
“DSC is a new
these services run”
What Does DSC provide?
PowerShell language extensions,
new Windows PowerShell cmdlets, and resources that you can use
to declaratively specify how you want your software environment to be
“DSC provides a set of Windows
configured.”
What are the advantages?
•
Avoid configuration drift
•
Keep configurations the same for all servers (all environments)
•
Easily create VMs from scratch for every deploy
•
On-premise or cloud (e.g. Azure)
So what?
•
Increase the (on going) assurance that deployment will succeed
•
Faster Deployments
•
Automate and simplify our deployments
How does it work?
•
Authoring Phase: Create Configuration PowerShell
•
Staging Phase: Create MOF file
•
Apply the configuration to the server
• Push
• Start-DscConfiguration
• Pull
• OData services to pull the details
•
Runs as System User
