一、k8s部署 方式

sts“. This can take up to 4m0s
[kube let–check] Initial timeout of 40s passed.

    Unfortunately, an error has occurred:
            timed out waiting for the condition

    This error is likely caused by:
            - The kubelet is not running
            - The kubelet is unhealthy due to a misconfiguration of the node in some way (required cgroups disabled)

    If you are on a systemd-powered system, you can try to troubleshoot the error with the following commands:
            - 'systemctl status kubelet'
            - 'journalctl -xeu kubelet'

    Additionally, a control plane component may have crashed or exited when started by the container runtime.
    To troubleshoot, list all containers using your preferred container runtimes CLI.

    Here is one example how you may list all Kubernetes containers running in docker:
            - 'docker ps -a | grep kube | grep -v pause'
            Once you have found the failing container, you can inspect its logs with:
            - 'docker logs CONTAINERID'

出现这个错误，我服了
