Configuration of CVM instances in TKE cluster

There is no need to manually configure CVM instances in the TKE cluster. The cluster automatically installs Docker service and configures Mirror Image when creating nodes. The default configuration items are as follows:

[root@VM_1_2_centos ~]# cat /etc/docker/dockerd 
IPTABLES="--iptables=false"
STORAGE_DRIVER="--storage-driver=overlay2"
IP_MASQ="--ip-masq=false"
LOG_LEVEL="--log-level=warn"
REGISTRY_MIRROR="--registry-mirror=https://mirror.ccs.tencentyun.com"
