当heketi端点不在pv和PVC的名称空间中时，glusterfs如何创建卷？
当heketi端点不在pv和PVC的名称空间中时，glusterfs如何创建卷？
提问于 2020-03-08 08:26:47
我有两个名称空间'runsdata‘和’监控‘。heketi和glusterfs的daemonSet荚都位于“runsdata”命名空间下。现在，我想在“监视”命名空间下创建Prometheus监视器。因为我需要存储普罗米修斯的数据。因此，我创建了PVC (在‘监控’ns下)和pv，在PVC yaml中，我声明存储库来创建相应的卷，以便为Prometheus提供存储。但是当我创建pv绑定并应用prometheus-server.yaml时。我知道错误：
Warning FailedMount 18m (x3 over 43m) kubelet, 172.16.5.151 Unable to attach or mount volumes: unmounted volumes=[prometheus-data-volume], unattached volumes=[prometheus-rules-volume prometheus-token-vcrr2 prometheus-data-volume prometheus-conf-volume]: timed out waiting for the condition
Warning FailedMount 13m (x5 over 50m) kubelet, 172.16.5.151 Unable to attach or mount volumes: unmounted volumes=[prometheus-data-volume], unattached volumes=[prometheus-token-vcrr2 prometheus-data-volume prometheus-conf-volume prometheus-rules-volume]: timed out waiting for the condition

解决方案是在当前命名空间下创建端点和服务。然后，我们可以使用pv中的服务，如下所示：
[root@localhost gluster]# cat glusterfs-endpoints.yaml
---
kind: Endpoints
apiVersion: v1
metadata:
name: glusterfs-cluster
namespace: monitoring
subsets:
- addresses:
- ip: 172.16.5.150
- ip: 172.16.5.151
- ip: 172.16.5.152
ports:
- port: 1
protocol: TCP
[root@localhost gluster]# cat glusterfs-service.yaml
apiVersion: v1
kind: Service
metadata:
name: glusterfs-cluster
namespace: monitoring
spec:
ports:
- port: 1
