Configuration error: the failure to start may be due to incorrect parameters in the configuration file or incomplete configuration.
Insufficient resources: If a node within the cluster lacks resources like memory, CPU, etc., it may cause k8s to fail to start properly.
Network issues, such as incorrect network configurations or malfunctioning network plugins, can also cause k8s startup failures.
Storage issue: Incorrect storage configuration or malfunctioning storage plugins can also result in the failure of k8s startup.
Container issues such as failed image downloads and inability to start properly can also result in k8s startup failure.
Issue with logs: If there are error messages in the logs of the k8s startup, you can determine the specific reason for the startup failure by examining the logs.
