报错详情:
you can check the kubelet logs for further clues by running:
- ‘journalctl -u kubelet’
Alternatively, there might be issues with your Kubernetes configuration files or maybe the necessary ports are not opened.
Check the status of your Kubernetes configuration files located at “/etc/kubernetes/manifests”. If anything is missing or wrong, the kubelet may not start correctly.
Check if the necessary ports are open on your machine, particularly port 10248 which kubelet uses.
Sometimes, ensure that the necessary cgroups are enabled can resolve this kubelet issue.
To inspect and manage cgroups, you may need to install additional tools like ‘cgroup-tools’. Check your operating system’s documentation to verify whether cgroups are supported and how to manage them.
Please note that the above troubleshooting steps are based on general knowledge about Kubernetes and kubelet process. The exact solution could be different based on the specific configuration and environment.
解决:
一、
问题看起来是kubelet无法正常运行或状态不健康。这可能是由于节点配置错误(例如禁用了必要的cgroups)。
如果你的系统是由systemd驱动的,你可以尝试使用以下命令去排查错误:
- ‘systemctl status kubelet’
- ‘journalctl -xeu kubelet’
此外,你也可以检查kubelet的日志来获取更多的详细信息,可能会有助于你识别问题和解决问题。通常,kubelet的日志可以在/var/log/syslog或者journalctl -u kubelet处找到。
二、
这可能和您的系统配置或版本兼容性有关。如果kubelet需要特定的cgroups设置,并且在系统上没有正确配置,那么这可能会引发错误。这也可能是Kubernetes和您的操作系统之间存在版本兼容性问题。
要解决此问题,您可以参阅Kubernetes的官方文档,检查系统的要求并确保满足这些要求。或者,您可以尝试在不同的系统或Kubernetes版本上运行来解决兼容性问题。
如果这还是不能解决您的问题,建议你查看kubelet的日志(使用命令’journalctl -xeu kubelet’),找出更具体的错误信息,以便更精确地定位问题。
经验证确定是操作系统兼容性问题,centos7.3一直报这个错误。选择centos7.6可以初始化成功
