1. 检查AWS Fargate EKS Pod的Iam Role是否有访问postgre RDS的权限

          resources:
            - eks:DescribeNodegroup
            - eks:DescribeAcl
            # Allow pods to communicate with RDS
            - rds:Connect
            - rds:DescribeDBInstances
            - rds:DescribeDBClusterEndpoints
            - rds:DescribeDBClusters
          effect: "Allow"

2. 确认数据库连接字符串是否正确设置

v1:
  kind: Secret
  metadata:
    name: sonarqube-postgres
  type: Opaque
  stringData:
    postgres-user: "{{ .Values.sonarqube.postgres.username }}"
    postgres-password: "{{ .Values.sonarqube.postgres.password }}"
    postgres-host: "{{ .Values.sonarqube.postgres.host }}"
    postgres-port: "{{ .Values.sonarqube.postgres.port }}"
    postgres-dbname: "{{ .Values.sonarqube.postgres.dbname }}"

3. 通过以下命令调试是否能够连接到RDS数据库

$ kubectl exec -it sonarqube-postgresql-0 -- /bin/bash
$ psql -h  -d  -U  -W
