1.配置tanzu控制节点为单节点

1.1.修改控制节点数量参数

需要通过ssh登录vcenter,并进入bash shell

• 查看/etc/vmware/wcp/wcpsvc.yaml中控制节点数量

root@localhost [ ~ ]# sed -n '18,20p' /etc/vmware/wcp/wcpsvc.yaml 
clusterconfig:
  minmasters: 3
  maxmasters: 3
root@localhost [ ~ ]# 

• 修改控制节点最小和最大数量为1

sed -i 's#minmasters: 3#minmasters: 1#g' /etc/vmware/wcp/wcpsvc.yaml
sed -i 's#maxmasters: 3#maxmasters: 1#g' /etc/vmware/wcp/wcpsvc.yaml

• 查看修改后的配置

root@localhost [ ~ ]# sed -n '18,20p' /etc/vmware/wcp/wcpsvc.yaml 
clusterconfig:
  minmasters: 1
  maxmasters: 1
root@localhost [ ~ ]# 

1.2.修改控制节点磁盘模式为精简模式

• 默认情况下，磁盘类型为厚置备模式

root@localhost [ ~ ]# grep 'thick' /etc/vmware/wcp/wcpsvc.yaml 
  controlplane_vm_disk_provisioning: "thick"

• 修改thick为thin

sed -i 's#thick#thin#g' /etc/vmware/wcp/wcpsvc.yaml 

• 确认配置已经修改

root@localhost [ ~ ]# grep 'thin' /etc/vmware/wcp/wcpsvc.yaml 
  # always disabled, and toggling this does not do anything.
  controlplane_vm_disk_provisioning: "thin"
  # The user takes a backup of VC => creates new namespaces => something catastrophic on VC happens and user uses the backup to restore VC
  # => after restore, VC/WCP DB  knows nothing about the namespaces; but the Kubernetes cluster still knows about them. In this scenario, we should create those missing namespaces in VC DB before
root@localhost [ ~ ]# 

1.3.重启wcp服务

service-control --restart wcp
