起因

开发反馈habor镜像库登陆不了，初步查看是证书过期了。

解决方案 之前Harbor-helm部署镜像库文档可以回顾链接https://minminmsn.com/middleware/698/ 1.首先新建新证书的secret

[root@elasticsearch01 harbor-helm]#  kubectl  create secret tls ingress-secret2021 --key minminmsnauto.key --cert minminmsnauto.crt

2.然后修改harbor-helm的value.yaml，把secretName替换下

[root@elasticsearch01 harbor-helm]# head -n 20 values.yaml
expose:
  # Set the way how to expose the service. Set the type as "ingress", 
  # "clusterIP" or "nodePort" and fill the information in the corresponding 
  # section
  type: ingress
  tls:
    # Enable the tls or not. Note: if the type is "ingress" and the tls 
    # is disabled, the port must be included in the command when pull/push
    # images. Refer to https://github.com/goharbor/harbor/issues/5291 
    # for the detail.
    enabled: true
    # Fill the name of secret if you want to use your own TLS certificate
    # and private key. The secret must contain keys named tls.crt and 
    # tls.key that contain the certificate and private key to use for TLS
    # The certificate and private key will be generated automatically if 
    # it is not set
    secretName: "ingress-secret2021"
    # By default, the Notary service will use the same cert and key as
    # described above. Fill the name of secret if you want to use a 
    # separated one. Only needed when the type is "ingress".

3.最后使用helm upgrade更新版本

[root@elasticsearch01 harbor-helm]#  helm upgrade  minminmsn . -f values.yaml

到这个时候应该能解决需求，可是事与愿违，不知道哪儿除了问题，这时登陆Harbor证书问题是解决了，但是项目及库访问不了提示内部错误，看Pod的运行状态也都是Running。最后打算使用helm先delete掉再install，但是这样创建的harbor看起来一切正常，实际上是个初始化环境，是自动生成的新PV并没有原来的数据。此时发现原来的PV还在，下面就开始找PV恢复的方案。

调整PV状态

1.查询此时PV与PVC状态

[root@elasticsearch01 harbor-helm]# kubectl get pv
NAME                                       CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS     CLAIM                                            STORAGECLASS   REASON   AGE                    9h

[root@elasticsearch01 harbor-helm]# kubectl get pvc

2.修改PV状态先把PV的状态由Released改变成备注：默认创建的PV的回收策略是Delete就是用完就删除，之前特意把RECLAIM POLICY改为了Retain，在线修改PV回收策略可以参考文档https://minminmsn.com/cloud/1091/。否则这里Helm Delete后就会自动删除PV，就没有后来这篇PV数据恢复操作了。在线编辑PV,需要把其中claimRef这段删除，这样状态就可以变成Available了。

  claimRef:
    apiVersion: v1
    kind: PersistentVolumeClaim
    name: minminmsn-harbor-chartmuseum
    namespace: default
    resourceVersion: "91736092"
    uid: b31ec8ca-c649-11ea-9386-52540089b2b6
  persistentVolumeReclaimPolicy: Retain

具体如下修改

[root@elasticsearch01 harbor-helm]# kubectl edit pv pvc-e7967cfe-7ded-11e9-a09d-52540089b2b6 
# Please edit the object below. Lines beginning with a '#' will be ignored,
# and an empty file will abort the edit. If an error occurs while saving this file will be
# reopened with the relevant failures.
#
apiVersion: v1
kind: PersistentVolume

3.其他四个PV同样操作

[root@elasticsearch01 harbor-helm]# kubectl edit pv pvc-e7974d1c-7ded-11e9-a09d-52540089b2b6
[root@elasticsearch01 harbor-helm]# kubectl edit pv pvc-e7985b55-7ded-11e9-a09d-52540089b2b6
[root@elasticsearch01 harbor-helm]# kubectl edit pv pvc-e7d38097-7ded-11e9-a09d-52540089b2b6
[root@elasticsearch01 harbor-helm]# kubectl edit pv pvc-e7da3f3c-7ded-11e9-a09d-52540089b2b6

4.查看效果现在看PV的STATUS已经变成了Available，然后CLAIM也变空了，这样就可以在后面绑定使用了

[root@elasticsearch01 harbor-helm]# kubectl get pv
NAME                                       CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS      CLAIM                       STORAGECLASS   REASON   AGE

pvc-e7974d1c-7ded-11e9-a09d-52540089b2b6   20Gi       RWO            Retain           Available                               rbd                     417d
pvc-e7985b55-7ded-11e9-a09d-52540089b2b6   2000Gi     RWO            Retain           Available                               rbd                     417d
pvc-e7d38097-7ded-11e9-a09d-52540089b2b6   20Gi       RWO            Retain           Available                               rbd                     417d
pvc-e7da3f3c-7ded-11e9-a09d-52540089b2b6   20Gi       RWO            Retain           Available                               rbd                     417d

创建PVC

1.先设置好PVC及PV对应关系

[root@elasticsearch01 yaml]# cat minminmsn.pvc 
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: minminmsn-harbor-registry
spec:
  accessModes:
    - ReadWriteOnce
  storageClassName: "rbd"
  resources:
    requests:
      storage: 2000Gi
  volumeName: "pvc-e7985b55-7ded-11e9-a09d-52540089b2b6"
---
apiVersion: v1

---
apiVersion: v1

    requests:
      storage: 20Gi
  volumeName: "pvc-e7da3f3c-7ded-11e9-a09d-52540089b2b6"

2.创建PVC

[root@elasticsearch01 yaml]# kubectl apply -f minminmsn.pvc 
persistentvolumeclaim/minminmsn-harbor-registry created
persistentvolumeclaim/minminmsn-harbor-jobservice created
persistentvolumeclaim/minminmsn-harbor-chartmuseum created
persistentvolumeclaim/database-data-minminmsn-harbor-database-0 created
persistentvolumeclaim/data-minminmsn-harbor-redis-0 created

3.检查PV与PVC

[root@elasticsearch01 yaml]# kubectl get pv

使用Hlem重新部署Harbor镜像库

1.部署前先删除版本

[root@elasticsearch01 harbor-helm]# helm delete --purge minminmsn
helm delete --purge minminmsn
release "minminmsn" deleted

2.修改Harbor-helm的values.yaml中PVC相关值注意existingClaim: ""由空值改成上面生成的PVC名字，注意对应关系，其他不变，具体变更如下

persistence:
  enabled: true
  # Setting it to "keep" to avoid removing PVCs during a helm delete 
  # operation. Leaving it empty will delete PVCs after the chart deleted
  resourcePolicy: "keep"
  persistentVolumeClaim:
    registry:
      # Use the existing PVC which must be created manually before bound
      existingClaim: "minminmsn-harbor-registry"
      # Specify the "storageClass" used to provision the volume. Or the default
      # StorageClass will be used(the default).
      # Set it to "-" to disable dynamic provisioning
      storageClass: "rbd"
      subPath: ""
      accessMode: ReadWriteOnce
      size: 2000Gi
    chartmuseum:
      existingClaim: "minminmsn-harbor-chartmuseum"
      storageClass: "rbd"
      subPath: ""
      accessMode: ReadWriteOnce
      size: 50Gi
    jobservice:
      existingClaim: "minminmsn-harbor-jobservice"
      storageClass: "rbd"
      subPath: ""
      accessMode: ReadWriteOnce
      size: 20Gi
    # If external database is used, the following settings for database will 
    # be ignored
    database:
      existingClaim: "database-data-minminmsn-harbor-database-0"
      storageClass: "rbd"
      subPath: ""
      accessMode: ReadWriteOnce
      size: 20Gi
    # If external Redis is used, the following settings for Redis will 
    # be ignored
    redis:
      existingClaim: "data-minminmsn-harbor-redis-0"
      storageClass: "rbd"
      subPath: ""
      accessMode: ReadWriteOnce
      size: 20Gi

3.重新部署
