5.7. 验证您的部署

执行以下步骤来验证部署。

独立模式的安装验证

运行以下命令，检查 app-storage 命名空间安装：

# switch to the app-storage namespace
oc project app-storage

# get the list of pods here (1 heketi pod)
oc get pods
NAME                    READY          STATUS          RESTARTS          AGE

heketi-storage-1-v5skm  1/1            Running         0                 1h

运行以下命令，或安装了 OC CLI 的 ansible 部署主机，以检查 infra-storage 命名空间的安装。

# switch to the infra-storage namespace
oc project infra-storage

# list the pods here (1 heketi pod and 1 glusterblock-provisioner pod)
oc get pods
NAME                                              READY   STATUS       RESTARTS       AGE
glusterblock-registry-provisioner-dc-1-28sfc         1/1  Running      0              1h
heketi-registry-5-lht6s                              1/1  Running      0              1h

检查 OCP 基础架构 Red Hat Openshift Container Storage 支持的 registry PVC 是否存在。此卷由 openshift-ansible 部署静态置备。

oc get pvc -n default
NAME                      STATUS      VOLUME                                    CAPACITY         ACCESSMODES      STORAGECLASS               AGE
registry-claim            Bound       pvc-7ca4c8de-10ca-11e8-84d3-069df2c4f284  25Gi             RWX                                         1h

检查 registry DeploymentConfig，以验证它是否使用此 glusterfs 卷。

oc describe dc/docker-registry -n default | grep -A3 Volumes
    Volumes:
    registry-storage:
    Type: PersistentVolumeClaim (a reference to a PersistentVolumeClaim in the same namespace)
    ClaimName: registry-claim

独立模式的存储置备验证

使用在 OCP 部署期间创建的 glusterfs 和 glusterblock OCP 存储类验证 PV 置备。两个存储类资源 glusterfs-storage 和 glusterfs-storage-block 可用于创建新的 PV 声明来验证 Red Hat Openshift Container Storage 部署。使用 glusterfs-storage storageclass 的新 PVC 将使用 app-storage 项目中的 gluster pod 可用存储。

# oc get storageclass

NAME                                TYPE
glusterfs-storage                   kubernetes.io/glusterfs
glusterfs-storage-block             gluster.org/glusterblock
$ cat pvc-file.yaml
kind: PersistentVolumeClaim
apiVersion: v1
spec:
  name: rhocs-file-claim1
  annotations:
  storageClassName: glusterfs-storage
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
storage: 5Gi

# cat pvc-block.yaml

kind: PersistentVolumeClaim
apiVersion: v1
spec:
  name: rhocs-block-claim1
  annotations:
  storageClassName: glusterfs-storage-block
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 5Gi

# oc create -f pvc-file.yaml
# oc create -f pvc-block.yaml
+

验证两个 PVC 和对应的 PV 是否已正确创建：

# oc get pvc

使用 heketi-client 进行验证

heketi-client 软件包需要安装到 ansible 部署主机或 OCP 主控机上。安装两个新文件后，即可轻松导出所需的环境变量以运行 heketi-client 命令（或 heketi-cli）。此处详细介绍了每个文件的内容以及 heketi-cli 命令。

创建包含以下内容的新文件（如"heketi-exports-app"）

export HEKETI_POD=$(oc get pods -l glusterfs=heketi-storage-pod -n app-storage -o jsonpath="{.items[0].metadata.name}")
export HEKETI_CLI_SERVER=http://$(oc get route/heketi-storage -n app-storage -o jsonpath='{.spec.host}')
export HEKETI_CLI_KEY=$(oc get pod/$HEKETI_POD -n app-storage -o jsonpath='{.spec.containers[0].env[?(@.name=="HEKETI_ADMIN_KEY")].value}')
export HEKETI_ADMIN_KEY_SECRET=$(echo -n ${HEKETI_CLI_KEY} | base64)
export HEKETI_CLI_USER=admin

提供该文件以创建 HEKETI app-storage 环境变量：

source heketi-exports-app
# see if heketi is alive
curl -w '\n' ${HEKETI_CLI_SERVER}/hello
Hello from Heketi
# ask heketi about the cluster it knows about
heketi-cli cluster list
Clusters:
Id:56ed234a384cef7dbef6c4aa106d4477 [file][block]
# ask heketi about the topology of the RHOCS cluster for apps
heketi-cli topology info
# ask heketi about the volumes already created (one for the heketi db should exist after the OCP initial installation)
heketi-cli volume list
Id:d71a4cbea22af3453615a9020f261b5c Cluster:56ed234a384cef7dbef6c4aa106d4477
Name:heketidbstorage

创建包含以下内容的新文件（如 "heketi-exports-infra"）:

export HEKETI_POD=$(oc get pods -l glusterfs=heketi-registry-pod -n infra-storage -o jsonpath="{.items[0].metadata.name}")
export HEKETI_CLI_SERVER=http://$(oc get route/heketi-registry -n infra-storage -o jsonpath='{.spec.host}')
export HEKETI_CLI_USER=admin
export HEKETI_CLI_KEY=$(oc get pod/$HEKETI_POD -n infra-storage -o jsonpath='{.spec.containers[0].env[?(@.name=="HEKETI_ADMIN_KEY")].value}')
export HEKETI_ADMIN_KEY_SECRET=$(echo -n ${HEKETI_CLI_KEY} | base64)

提供该文件以创建 HEKETI infra-storage 环境变量：

source heketi-exports-infra
# see if heketi is alive
curl -w '\n' ${HEKETI_CLI_SERVER}/hello
Hello from Heketi
# ask heketi about the cluster it knows about (the RHOCS cluster for infrastructure)
heketi-cli cluster list
Clusters:
Id:baf91b261cbca2bb4b62caece63f60d0 [file][block]
# ask heketi about the volumes already created
heketi-cli volume list
Id:77baed02f79f4518326d8cc1db6c7af8 Cluster:baf91b261cbca2bb4b62caece63f60d0 Name:heketidbstorage
