Course Outline
Course Introduction
Let's kick off with why you should care about template specs, and what problem they aim to solve. We'll spend a few minutes covering:
- The course agenda
- The "101" of Template Specs
- Prerequisites if you'd like to follow along
Work With Template Specs in Azure Portal
Now you're across the "what" of Template Specs, let's start diving in to the "how", and a good starting point is using the Azure Portal.
- Create a template spec in the Azure Portal
- View template spec properties
- Work with different versions of a template spec
- Deploy resources (a VNET) from a template spec
Work with Template Specs in PowerShell
I like to use the Azure Portal to get a good visual of how a service or system works, but some true power can be achieved by using an automation language like PowerShell. Microsoft have commands to work with template specs, and that's what we'll dive in to in this clip.
- Clone a git repository that contains some ARM templates
- Create a new template spec using PowerShell
- Get information about template specs using PowerShell
- Deploy resources (a storage account) from a template spec using PowerShell
Template Specs and Linked Templates
Linked templates are popular when designing and creating ARM templates to provide a modular method for resource deployment, but historically it has come with challenges. In this clip, we'll understand how using linked templates in template specs makes this much easier.
- A high level recap of how linked templates work
- How they are different with template specs
- Use PowerShell to create a template spec that contains a linked template
- Explore the new template spec in PowerShell and in the Portal
Using CICD To Test ARM Templates and Deploy to Template Specs
You've learned the benefits that template specs provide, and you now know template specs contain their own versioning system, but you can still use a git repository to store and version your ARM templates, and even use a pipeline to automatically deploy ARM templates to template specs.
- Understand how a git repository and CICD can work with template specs
- Set up an Azure DevOps project and push our git repository to DevOps
- Explore a YAML based pipeline that with test and deploy an ARM template
- Trigger the pipeline manually and explore the result
- Modify the ARM template and observe end-to-end CICD to create a new version of the template spec
