This is docker's default dependency, and ks has not modified it here.

In order to create clusters quickly, kk provides the ability to install docker, and uses official scripts (curl -fsSL https://get.docker.com -o get-docker.sh) to install docker.

[oldthreefeng]

ok, may be some cri (containerd) has already installed before kk install.

@pixiake can you help me find the install docker code in kk ?

Only one script was used to install docker.
