Harvester Shell
以使用 F12 可以从 Harvester 控制台切换到 Shell,然后键入 exit 返回 Harvester 控制台。
Harvester VIP
- 如何获取 VIP MAC
harvester-1:~ # kubectl get svc -n kube-system ingress-expose -ojsonpath='{.metadata.annotations}'
{"kube-vip.io/hwaddr":"de:6d:6a:77:9f:ff","kube-vip.io/ignore-service-security":"true","kube-vip.io/loadbalancerIPs":"0.0.0.0","kube-vip.io/requestedIP":"10.201.170.140","kube-vip.io/vipHost":"harvester-1"}
- 确认 VIP 被分配到的主机
harvester-1:~ # kubectl -n kube-system get svc ingress-expose -o jsonpath='{.metadata.annotations.kube-vip\.io/vipHost}'
harvester-1
或者挨个登录到 Harvester node,执行 ip address show mgmt-br
确认:
harvester-1:~ # ip address show mgmt-br
6: mgmt-br: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
link/ether 00:22:19:69:56:53 brd ff:ff:ff:ff:ff:ff
inet 10.201.170.138/22 brd 10.201.171.255 scope global mgmt-br
valid_lft forever preferred_lft forever
inet 10.201.170.140/32 scope global mgmt-br
valid_lft forever preferred_lft forever
如果集群只有两个控制平面节点,Harvester 不允许您在任何节点上启用维护模式。您可以使用以下命令手动清空要移除的节点:
kubectl drain <node_name> --force --ignore-daemonsets --delete-local-data --pod-selector='app!=csi-attacher,app!=csi-provisioner'
主机添加磁盘
如果主机上已经挂载磁盘,但在 harvester 上添加磁盘提示:sorry, no matching options

设置备份目标
对接 minio,Endpoint 设置为 运行 minio 暴漏的端口,并不是 UI 访问的端口,本例为: 31900
docker run -itd -p 31900:9000 -p 31901:9001 --name minio -v /opt/minio/data:/data -e "MINIO_ROOT_USER=admin" -e "MINIO_ROOT_PASSWORD=xxx" minio/minio:RELEASE.2023-04-28T18-11-17Z server /data --console-address ":9001"
疑问:
- 创建 vm 的时候为什么可以选择两个 storageclass ?
- LB 的轮询策略在哪修改
- volume 创建 镜像的 volume 有什么用
- 导出 volume 有什么用?
- 卷快照的恢复,是用快照生成一个新卷,然后重新挂载到 vm ?
- harvester 配置 containerd 代理
