Offline environment installation

The offline environment only needs to import the image in advance, and other steps are the same as the online installation. First save the installation package in a networked environment：

$ sealos pull docker.io/labring/kubernetes:v1.25.6
$ sealos save -o kubernetes.tar docker.io/labring/kubernetes:v1.25.6

Copy kubernetes.tar to the offline environment, and use the load command to import the image:

$ sealos load -i kubernetes.tar

The rest of the installation method is the same as the online installation.

$ sealos images # Check whether the cluster image is imported successfully
$ sealos run docker.io/labring/kubernetes:v1.25.6 --single # Single machine installation, cluster installation is the same

Or without load command, sealos will auto load image.

sealos run kubernetes.tar --single
