kubernetes 部署 SonarQube

1.PostgreSQL

参考博客：https://hanggi.me/post/kubernetes/k8s-postgresql

1.1.配置PostgreSQL的ConfigMap

cat > postgres-configmap.yaml <<EOF
apiVersion: v1
kind: ConfigMap
metadata:
  name: postgres-config
  namespace: kube-ops
  labels:
    app: postgres
data:
  POSTGRES_DB: sonarDB
  POSTGRES_USER: postgresadmin
  POSTGRES_PASSWORD: admin12345
EOF
kubectl apply -f postgres-configmap.yaml

1.2.持久化卷Persistent StorageVolume

cat > postgres-volume.yaml <<EOF
---
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: postgres-pv-claim
  namespace: kube-ops
  labels:
    app: postgres
spec:
  storageClassName: nfs-storage
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 5Gi
EOF
kubectl apply -f postgres-volume.yaml

1.3.PostgreSQLDeployment

apiVersion: apps/v1
kind: Deployment
metadata:
  name: postgres-deployment
  namespace: kube-ops

  strategy:
    type: Recreate

      labels:
        app: postgres
    spec:
      containers:

          ports:
            - containerPort: 5432
          envFrom:
            - configMapRef:
                name: postgres-config
          volumeMounts:
            - mountPath: /var/lib/postgresql/data
              name: postgredb
      volumes:
        - name: postgredb
          persistentVolumeClaim:
            claimName: postgres-pv-claim
EOF
kubectl apply -f postgres-deployment.yaml
