9.3. Spring Boot Narayana 복구 컨트롤러 구성

절차

1. 샘플 application.properties 파일입니다. Kubernetes yaml 설명자에서 다음 옵션을 교체합니다.

   # Cluster
   cluster.nodename=1
   cluster.base-dir=./target/tx
   
   # Transaction Data
   spring.jta.transaction-manager-id=${cluster.nodename}
   spring.jta.log-dir=${cluster.base-dir}/store/${cluster.nodename}
   
   # Narayana recovery settings
   snowdrop.narayana.openshift.recovery.enabled=true
   snowdrop.narayana.openshift.recovery.current-pod-name=${cluster.nodename}
   # You must enable resource filtering in order to inject the Maven artifactId
   snowdrop.narayana.openshift.recovery.statefulset=${project.artifactId}
   snowdrop.narayana.openshift.recovery.status-dir=${cluster.base-dir}/status

2. 종료와 관련된 거래 및 정보를 모두 저장하려면 공유 볼륨이 필요합니다. 다음과 같이 StatefulSet yaml 설명자에 마운트할 수 있습니다.

   apiVersion: apps/v1
   kind: StatefulSet
   #...
   spec:
   #...
     template:
   #...
       spec:
         containers:
         - env:
           - name: CLUSTER_BASE_DIR
             value: /var/transaction/data
             # Override CLUSTER_NODENAME with Kubernetes Downward API (to use `pod-0`, `pod-1` etc. as tx manager id)
           - name: CLUSTER_NODENAME
             valueFrom:
               fieldRef:
                 apiVersion: v1
                 fieldPath: metadata.name
   #...
           volumeMounts:
           - mountPath: /var/transaction/data
             name: the-name-of-the-shared-volume
   #...
