问题描述:
cattle-cluster-agent始终无法启动

安装命令
curl --insecure -fL https://192.168.40.220/system-agent-install.sh | sudo sh -s - --server https://192.168.40.220 --label ‘cattle.io/os=linux’ --token 55hd59467fc45cdxlpt5n67nhv2rwpmnprmgf64vfdtxwlcrj4rcwp --ca-checksum dfc43177c7204bb998b3076aa1619c2c5110b3adf73f173b528ff0ea40d187bc --etcd --controlplane --worker

日志好像是连不上rancher,但是能ping通.是证书问题吗?该如何解决
[root@ky-test ~]# curl https://192.168.40.220/ping
curl: (60) SSL certificate problem: self signed certificate in certificate chain
More details here: https://curl.haxx.se/docs/sslcerts.html

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.

后续使用中感觉是K8S内部的DNS出了问题.创建的service,容器内部无法正常访问

已确认是麒麟系统/etc/sysctl.conf中几个关于ipv4默认参数为0导致不能创建vxlan .修改为1之后能够创建vxlan
calico-node能够正常运行
但是cattle-cluster-agent容器依然无法正常运行
查看日志无法访问rancher的ping接口
安装命令是带了–insecure

curl --insecure -fL https://192.168.40.220/system-agent-install.sh | sudo  sh -s - --server https://192.168.40.220 --label 'cattle.io/os=linux' --token tp4trblqqk9tbvzzkqbzjt74wx4bt9ftvh742s86qw5qxgtmjl2zl8 --ca-checksum dfc43177c7204bb998b3076aa1619c2c5110b3adf73f173b528ff0ea40d187bc --etcd --controlplane --worker

这个问题改如何解决呢?

cat /proc/sys/net/ipv4/ip_forward 查看下 主机的 ip_forward 的值,如果是 0,需要开启 ip_forward

image

麒麟 OS 是直接装在物理机上了,还是使用了某个 虚拟化平台?

暂时是虚拟化的

用的什么虚拟化平台?

virsh

我看了下coredns的日志
[root@jt ~]# kubectl logs -n kube-system -f pod/rke2-coredns-rke2-coredns-bcb9d866c-jb9dv
[INFO] plugin/kubernetes: pkg/mod/k8s.io/client-go@v0.27.4/tools/cache/reflector.go:231: failed to list *v1.EndpointSlice: Get “https://10.43.0.1:443/apis/discovery.k8s.io/v1/endpointslices?limit=500&resourceVersion=0”: dial tcp 10.43.0.1:443: connect: no route to host

感觉十有八九是主机之间网络的问题,之前在社区里遇到过由于使用的是 深信服的平台导致的类似问题。

好的.感谢你!
