4장. OpenShift Container Platform에서 Ansible 자동화 컨트롤러 구성

프로세스

1. AutomationController 사양에서 RECEPTOR_KUBE_SUPPORT_RECONNECT 를 활성화합니다.

   apiVersion: automationcontroller.ansible.com/v1beta1
   kind: AutomationController
   metadata:
     ...
   spec:
     ...
     ee_extra_env: |
       - name: RECEPTOR_KUBE_SUPPORT_RECONNECT
         value: enabled
       ```

2. AutomationController 사양에서 정상 종료 기능을 활성화합니다.

   termination_grace_period_seconds: <time to wait for job to finish>

3. AutomationController 사양의 배포를 분배하도록 Pod가 웹에 대해 podAntiAffinity 를 구성합니다.

   task_affinity:
       podAntiAffinity:
         preferredDuringSchedulingIgnoredDuringExecution:
         - podAffinityTerm:
             labelSelector:
               matchExpressions:
               - key: app.kubernetes.io/name
                 operator: In
                 values:
                 - awx-task
             topologyKey: topology.kubernetes.io/zone
           weight: 100
     web_affinity:
       podAntiAffinity:
         preferredDuringSchedulingIgnoredDuringExecution:
         - podAffinityTerm:
             labelSelector:
               matchExpressions:
               - key: app.kubernetes.io/name
                 operator: In
                 values:
                 - awx-web
             topologyKey: topology.kubernetes.io/zone
           weight: 100

4. OpenShift Container Platform에서 PodDisruptionBudget 을 구성합니다.

   ---
   apiVersion: policy/v1
   kind: PodDisruptionBudget
   metadata:
     name: automationcontroller-job-pods
   spec:
     maxUnavailable: 0
     selector:
       matchExpressions:
         - key: ansible-awx-job-id
           operator: Exists
   ---
   apiVersion: policy/v1
   kind: PodDisruptionBudget
   metadata:
     name: automationcontroller-web-pods
   spec:
     minAvailable: 1
     selector:
       matchExpressions:
         - key: app.kubernetes.io/name
           operator: In
           values:
             - <automationcontroller_instance_name>-web
   ---
   apiVersion: policy/v1
   kind: PodDisruptionBudget
   metadata:
     name: automationcontroller-task-pods
   spec:
     minAvailable: 1
     selector:
       matchExpressions:
         - key: app.kubernetes.io/name
           operator: In
           values:
             - <automationcontroller_instance_name>-task
