Running traffic-splitting jobs on self-hosted runners with Azure Pipelines can optimize your deployment process by routing a certain percentage of traffic to different versions of your application. This allows you to test new features or bug fixes in real-time without affecting your entire user base.
To set up traffic splitting in Azure Pipelines on self-hosted runners, you can define your pipeline configuration in your YAML file. Below is an example of how to implement this:
jobs:
- job: TrafficSplit
pool:
name: 'SelfHostedPool'
steps:
- script: echo "Deploying version A"
displayName: 'Deploy Version A'
condition: and(succeeded(), eq(variables['SplitTraffic'], 'A'))
- script: echo "Deploying version B"
displayName: 'Deploy Version B'
condition: and(succeeded(), eq(variables['SplitTraffic'], 'B'))
variables:
SplitTraffic: $[ if(eq(variables['Build.SourceBranch'], 'refs/heads/main'), 'A', 'B') ]
