我第一次尝试在我的笔记本电脑上运行 Minikube v1.19.0，使用 Docker 作为驱动程序，但没有成功。以下是执行日志：

我有一个运行着多个永久性磁盘用于存储的 GKE 集群。为了设置临时环境，我在同一项目中创建了第二个集群。现在我想在登台集群中使用生产集群的永久磁盘中的数据。

我已经为临时集群创建了永久性磁盘。将生产数据移动到临时集群磁盘的最佳方法是什么？

我有一个 postgres 部署，其配置如下

apiVersion: postgres-operator.crunchydata.com/v1beta1
kind: PostgresCluster
metadata:
  name: hippo
spec:
  image: registry.developers.crunchydata.com/crunchydata/crunchy-postgres:centos8-13.5-0
  postgresVersion: 13
  users:
  - name: hippo
    databases: ["hippo"]
    options: "CREATEDB"
  instances:
  - name: instance1
    dataVolumeClaimSpec:
      accessModes:
      - "ReadWriteOnce"
      resources:
        requests:
          storage: 1Gi
  backups:
    pgbackrest:
      image: registry.developers.crunchydata.com/crunchydata/crunchy-pgbackrest:centos8-2.36-0
      repos:
      - name: repo1
        volume:
          volumeClaimSpec:
            accessModes:
            - "ReadWriteOnce"
            resources:
              requests:
                storage: 1Gi

我将本地端口 5432 转发给它，就像这样

DB_PORT=5432
PG_CLUSTER_PRIMARY_POD=$(microk8s kubectl get pod -o name \
-l postgres-operator.crunchydata.com/cluster=hippo,postgres-operator.crunchydata.com/role=master)
microk8s kubectl port-forward "${PG_CLUSTER_PRIMARY_POD}" ${DB_PORT}:${DB_PORT}

然后我可以通过 psql 连接。我可以列出数据库并连接到 hippo 数据库。

rob@rob-Vostro-5402:~$ psql postgresql://hippo:Zw%5EAQuPf%3D%3Bi%3B%3F2%3E1RRbLTLrT@localhost:5432/hippo
