Rollouts CRD

The Rollout CRD is installed to your cluster when you install Argo Rollouts. This is similar to a Deployment, but it adds a rollout strategy section that defines how the rollout will incrementally happen once started. In the example below, it will route 30% of traffic to the new service for 30 seconds, followed by 60% of the traffic for another 30 seconds, then 100% of the traffic. Example YAML:

          ports:

  strategy:
    canary:
      stableService: example-stable  # must match your service name
      canaryService: example-canary  # must match your service name
      trafficRouting:  # this section required to use Edge Stack for routing

      steps:    # describes the strategy for sending traffic to the canary
      - setWeight: 30   # 30% of the traffic will go to the canary for 30 seconds
      - pause: {duration: 30}
      - setWeight: 60   # 60% of the traffic will go to the canary for 45 seconds   
      - pause: {duration: 45}
      - setWeight: 100  # 100% of the traffic will go to the canary for 10 seconds 
      - pause: {duration: 10}
