To clarify on what the expected results are: During MinReadySecond period: AvailableReplicas == 0 && ReadyReplicas==Replicas && UnavailableReplicas==Replicas Couldn't found the latest ami on EC2, will change the status to modified. Confirmed with latest ocp 3.6 version, the issue has fixed:

Description of problem: During the DC's MinReadySeconds, the pod is not ready for DC, but the DC's status: unavailableReplicas is 0 , and the readyReplicas equals to replicas asap. Version-Release number of selected component (if applicable): openshift v3.6.121 kubernetes v1.6.1+5115d708d7 etcd 3.2.0 How reproducible: always Steps to Reproduce: 1. Login openshift and create project; 2. Create a DC with file: apiVersion: v1 kind: DeploymentConfig metadata: name: minreadytest spec: replicas: 2 minReadySeconds: 50 selector: name: minreadytest template: metadata: labels: name: minreadytest spec: terminationGracePeriodSeconds: 0 containers: - image: "docker.io/centos:centos7" imagePullPolicy: IfNotPresent name: myapp command: - /bin/sleep - "10000" 3. Check the dc's status. Actual results: 3. During the DC's MinReadySeconds, the unavailableReplicas is 0 and readyReplicas equals to replicas. Expected results: 3. During the DC's MinReadySeconds, the pod is not ready for DC, so the unavailableReplicas should equal to replicas, and the readyReplicas should be 0. Additional info:
