### Options
--k8s-version set the kubernetes k8s_version of the Clusterimage, k8s_version must be greater than 1.13
-c, --cri cri can be set to docker or containerd between kubernetes 1.20-1.24 versions
-n, --buildName set build image name, default is 'registry.cn-qingdao.aliyuncs.com/sealer-io/kubernetes:${k8s_version}'
--platform set the build mirror platform, the default is linux/amd64,linux/arm64
--push push clusterimage after building the clusterimage. The image name must contain the full name of the repository, and use -u and -p to specify the username and password.
-u, --username specify the user's username for pushing the Clusterimage
-p, --password specify the user's password for pushing the Clusterimage
-d, --debug show all script logs
-h, --help help for auto build shell scripts"
