Reusability

Parameter & Variables

• Azure DevOps Pipeline Variables
• Azure DevOps has lots of predefined variables with information about
  • build
  • agent
  • ..
• Allows us to use Environmental Variables
• Allows to create user defined variables
• Allows to organize variables in a variable group

Exercise:

• Add publish in the devops ci pipeline which runs once every 2 hours
• Also add configuration = Release for CI and configuration = Debug for PR pipeline
