kuberneters采用helm部署sig-storage-local-static-provisioner

https://github.com/kubernetes-sigs/sig-storage-local-static-provisioner/tags

 下载并解压tar包

wget https://github.com/kubernetes-sigs/sig-storage-local-static-provisioner/archive/v2.3.4.tar.gz
tar -zxvf v2.3.4.tar.gz

进入解压目录后创建storageclass

kubectl create -f deployment/kubernetes/example/default_example_storageclass.yaml

查看storageclass

kubectl get sc

创建目录/mnt/fast-disks

mkdir /mnt/fast-disks

安装local-volume-provisioner

查看文件系统

df -h -T

修改helm/provisioner/values.yaml

fsTyp默认为ext4格式，默认hostDir为/mnt/fast-disks，所有的文件系统都要挂载到该目录下

生成yaml文件

helm template ./helm/provisioner > deployment/kubernetes/provisioner_generated.yaml

部署provisioner

kubectl apply -f deployment/kubernetes/provisioner_generated.yaml

查看部署pod

kubectl get pods -o wide

由于一个挂载点对应一个pv，为了创建多个pv可以使用mount --bind方式,mount bind方式挂载

mount bind的一种用法，用于本地没有多余磁盘的情况

创建mount-bind.sh  shell脚本执行，配置完成后会自动创建pv

for i in $(seq 1 5); do
  mkdir -p /mnt/fast-disks-bind/vol${i}
  mkdir -p /mnt/fast-disks/vol${i}
  mount --bind /mnt/fast-disks-bind/vol${i} /mnt/fast-disks/vol${i}
done

# 配置/etc/fstab永久挂载
for i in $(seq 1 5); do
  echo /mnt/fast-disks-bind/vol${i} /mnt/fast-disks/vol${i} none bind 0 0 | sudo tee -a /etc/fstab
done

kubectl get pv

验证 创建pod，定义pvc申请使用pv
