本文档记录了在OpenShift环境中安装和配置Metrics子系统的步骤，包括创建PersistentVolume、登录、声明资源、执行openshift-metrics.yml文件，以及检查资源状态的过程。

1.lab install-metrics setup模拟创建环境（metrics-pv.yml资源文件所需及创建pv资源文件）。

[student@workstation ~]$ lab install-metrics setup

Checking prerequisites for GE: Installing the Metrics Subsystem

Checking all VMs are running:
· master VM is up............................................. SUCCESS
· node1 VM is up.............................................. SUCCESS
· node2 VM is up.............................................. SUCCESS

Downloading files for GE: Installing the Metrics Subsystem

· Download exercise files..................................... SUCCESS
· Download solution files..................................... SUCCESS
· Copy lab files to the master VM............................. SUCCESS
· Copy solution files to the master VM........................ SUCCESS

Overall setup status........................................... SUCCESS

2.cat metrics-pv.yml 查看资源文件内容。

[student@workstation install-metrics]$ pwd
/home/student/DO280/labs/install-metrics
[student@workstation install-metrics]$ cat metrics-pv.yml
apiVersion: v1
kind: PersistentVolume
metadata:
name: metrics
spec:
capacity:
storage: 5Gi
accessModes:
- ReadWriteOnce
nfs:
path: /exports/metrics
server: master.lab.example.com
persistentVolumeReclaimPolicy: Recycle
claimRef:
name: metrics-1
namespace: openshift-infra

3. oc login -u admin -p redhat https://master.lab.example.com:8443使用管理员登陆。oc apply -f metrics-pv.yml 声明资源。oc get pv -o wide查看pv资源。

[student@workstation install-metrics]$ oc login -u admin -p redhat https://master.lab.example.com:8443
Login successful.

You have access to the following projects and can switch between them with 'oc project <projectname>':

chicago
* default
ditto
farm
kube-system
logging
management-infra
openshift
openshift-infra
samples
squid

Using project "default".
[student@workstation install-metrics]$ oc apply -f metrics-pv.yml
persistentvolume "metrics" created
[student@workstation install-metrics]$ oc get pv -o wide
NAME CAPACITY ACCESSMODES RECLAIMPOLICY STATUS CLAIM REASON AGE
metrics 5Gi RWO Recycle Available openshift-infra/metrics-1 36s

4. oc login -u admin -p redhat https://master.lab.example.com:8443使用管理员登陆。ansible-playbook -i ~/hosts \

> /openshift-metrics.yml \
> -e openshift_metrics_image_prefix=workstation.lab.example.com:5000\

> -e openshift_metrics_cassandra_pvc_size=5Gi \
> -e openshift_metrics_cassandra_pvc_prefix=metrics \
> -e openshift_metrics_install_metrics=True执行openshift-metrics.yml文件（内容详见最后附注）并传入参数。
