    This issue is resolved, it was caused my network in China, now I changed to use aliyun repository, then it works now, attach my command for your reference:
    sudo kubeadm init --image-repository registry.cn-hangzhou.aliyuncs.com/google_containers --kubernetes-version 1.18.1 --pod-network-cidr

    if you got the same issue, you need to edit the k8sMaster.sh file and change it as above.

    Is it LFS258? Because in my course, there is no Lab2.2.

    Hi @rudysp,

    The previous post is from another course. Thanks for pointing this out, we should do some spring cleaning to avoid any confusion.

    You are fine, there is no 2.2 in LFS258.

    Hi @rudysp,

    There's no Lab 2.2 in the LFS258 course. This thread should be posted in the forum for Kubernetes for Developers (LFD259).

    Thank you,
