• To maintain collection of Agents, Azure has Agent pools. By default we will have two pools
  • default: for self hosted agents
  • Azure Pipelines: for Microsoft hosted agents
• Lets create a ubuntu linux vm and as discussed in the session install, configure and run the agent
  
• Azure Pipelines are represnted in YAML Format. YAML is used as a Data representation format
• YAML is name value pair collection
• syntax

<name>: <value>

• Value holds data and types of data are
  • Simple/Scalar
    • text: course: AzureDevOps or course: "AzureDevOps" or course: 'AzureDevOps'
    • number: duration: 120
    • boolean online: yes or online: true
  • Complex
