安装其他插件时必须先安装labring/helm:v3.8.2

sealos run labring/kubernetes-docker:v1.20.9 labring/helm:v3.8.2 labring/calico:v3.22.1 \
   --masters 172.12.1.102 --passwd 123456


sealos_v4.3.7

sealos run labring/kubernetes-docker:v1.22.17-4.3.7 labring/helm:v3.12.3 labring/calico:v3.24.6 --masters 172.12.1.150 --passwd 123456


sealos run labring/kubernetes-docker:v1.26.14-amd64 labring/helm:v3.14.1 labring/calico:v3.26.1-amd64 --masters 192.168.14.18 --passwd 123456
