Kubernetes安装local-path-provisioner基于HostPath使用动态PV（测试用）

获取local-path-provisioner

git clone https://github.com/rancher/local-path-provisioner.git

修改local-path-storage.yaml

vi local-path-provisioner/deploy/local-path-storage.yaml

修改前（修改部分）：

---
kind: ConfigMap
apiVersion: v1
metadata:
  name: local-path-config
  namespace: local-path-storage
data:
  config.json: |-
        {
                "nodePathMap":[
                {
                        "node":"DEFAULT_PATH_FOR_NON_LISTED_NODES",
                        "paths":["/opt/local-path-provisioner"]
                }
                ]
        }

修改后（修改部分）：

---
kind: ConfigMap
apiVersion: v1
metadata:
  name: local-path-config
  namespace: local-path-storage
data:
  config.json: |-
        {
                "nodePathMap":[
                {
                        "node":"DEFAULT_PATH_FOR_NON_LISTED_NODES",
                        "paths":["/u01/local-path-provisioner"]
                }
                ]
        }

创建文件路径

mkdir -p /u01/local-path-provisioner
chmod 777 /u01/local-path-provisioner

创建namespace

kubectl create ns local-path-storage

发布local-path-storage

kubectl apply -f local-path-provisioner/deploy/local-path-storage.yaml -n local-path-storage

确认发布结果

确认结果：

kubectl get po -n local-path-storage

结果如下：

NAME                                      READY   STATUS    RESTARTS   AGE
local-path-provisioner-54bbdbb5cc-7d8kw   1/1     Running   0          18m

确认结果：

kubectl get storageclass

结果如下：

NAME         PROVISIONER             AGE
local-path   rancher.io/local-path   18m

设置为default的storageclass

kubectl patch storageclass local-path -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
kubectl patch storageclass local-path -p '{"metadata": {"annotations":{"storageclass.beta.kubernetes.io/is-default-class":"true"}}}'

卸载

kubectl delete -f local-path-provisioner/deploy/local-path-storage.yaml
