![kubernetes pod 中的 kafka](https://linux22.com/image/746376/kubernetes%20pod%20%E4%B8%AD%E7%9A%84%20kafka.png)
我是使用 kubernetes 设置的新手,正在尝试使用持久卷运行 kafka pod,这样如果 pod 出现故障,内存不会丢失,并且我可以使用持久内存启动一个新的集群。
问题在于
我尝试在这里做一个
apiVersion: v1
kind: Service
metadata:
name: kafka
labels:
app: kafka
spec:
type: NodePort
ports:
- port: 9092
selector:
app: kafka
---
apiVersion: apps/v1
kind: StatefulSet
metadata:
name: kafka
spec:
selector:
matchLabels:
app: kafka
serviceName: "kafka"
template:

# httpGet:
# port: 7070
# path: /readiness
# initialDelaySeconds: 120
# periodSeconds: 15
# failureThreshold: 1
# livenessProbe:
# httpGet:
# port: 7070
# path: /liveness
# initialDelaySeconds: 360
# periodSeconds: 15
# failureThreshold: 3
ports:
- containerPort: 9092
volumeMounts:
- name: kafka
mountPath: /binami/kafka
volumeClaimTemplates:
- metadata:
name: datadir
spec:
accessModes: [ "ReadWriteOnce" ]
resources:
requests:
storage: 1Gi
但这似乎不起作用,由于某种原因,它进入错误状态,并显示错误消息:
pod has unbound immediate PersistentVolumeClaims
我不确定我是否理解了? - 该卷仅被其使用?
并且 pod 尚未重新启动,所以我很困惑为什么它不起作用?
