Installation

• 选择运行 localstorage 的 kubernetes 节点

  kubectl label node <node-name> storage.caoyingjunz.io/node=

• 安装 localstorage 组件

  kubectl apply -f deploy/crds
  kubectl apply -f deploy/latest
  
  # 验证
  root@pixiu01:~# kubectl get pod -n kube-system | grep pixiu
  pixiu-ls-controller-7997b8c446-8hndc        1/1     Running            0                87s

• 安装 LocalStorage 调度扩展

• 创建 localstorage 资源

  # 自动创建
  kubectl apply -f deploy/ls-job.yaml
  
  # 手动创建
  # 修改 examples/ls.yaml, 多个 node 节点需要多次创建
  kubectl apply -f examples/ls.yaml
  
  # 验证
  kubectl get ls
  NAME         STATUS   KUBENODE   ALLOCATABLE   CAPACITY   AGE
  ls-pixiu01   Ready    pixiu01    360Gi         360Gi      16d

• 安装 storageclass

  kubectl apply -f deploy/ls-storageclass.yaml
  
  # 验证
  kubectl get sc pixiu-localstorage
  NAME                 PROVISIONER                       RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE
  pixiu-localstorage   localstorage.csi.caoyingjunz.io   Delete          WaitForFirstConsumer   false                  2m54s

• 创建 pvc 验证

  kubectl apply -f examples/pvc.yaml
  
  # 验证
  kubectl get pvc
  NAME                 STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS              AGE
  test-pvc             Bound    pvc-2b2c809f-33b5-437f-a4b8-61906c10a3e1   1Mi        RWX            pixiu-localstorage        5s
