1. 部署 NFS 存储
1.1 在存储节点配置 NFS 服务
1
| apt-get install -y nfs-kernel-server
|
1
| systemctl start nfs-server.service & systemctl enable nfs-server.service
|
/data/nfs *(rw,sync,no_root_squash,no_all_squash)
1
| systemctl restart nfs-server.service
|
1.2 在全部节点配置 NFS 客户端
1
| apt-get install -y nfs-common
|
2 配置 StorageClass
1
2
| helm repo add csi-driver-nfs https://raw.githubusercontent.com/kubernetes-csi/csi-driver-nfs/master/charts
helm install csi-driver-nfs csi-driver-nfs/csi-driver-nfs --namespace kube-system --version v4.9.0

调整一下 download 中的 pieceTimeout 以便于下载大镜像文件。
1
| kubectl -n dragonfly-system rollout restart ds dragonfly-client
