kubeadm init phase certs apiserver --apiserver-advertise-address 192.168.1.110 --apiserver-cert-extra-sans 192.168.1.110

 

 

 

========

 

重置cert相关问题：

rm /etc/kubernetes/pki/apiserver.*

 

??  kubeadm init  phase certs all --apiserver-advertise-address=192.168.1.110 --apiserver-cert-extra-sans=192.168.1.110

 

docker rm -f `docker ps -q -f 'name=k8s_kube-apiserver*'`

systemctl restart kubelet

 

 

初始化：

kubeadm init --apiserver-cert-extra-sans=192.168.1.110,10.0.2.15,0.0.0.0  --apiserver-advertise-address 192.168.1.110  --pod-network-cidr=10.244.0.0/16 --v=5

 

 

 

?? —pod-network-cidr=192.168.0.1/24 

 

X509证书错误：

  mkdir -p $HOME/.kube

  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config

  sudo chown $(id -u):$(id -g) $HOME/.kube/config

 

 

查找token

kubeadm token create --print-join-command

kubeadm token list

 

加入

 

 

notready的问题：

1. kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

 

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

 

 

 

查看日志排查问题：

journalctl -f -u kubelet

 

 

 

 

配置缺失的问题：is missing FLANNEL_NETWORK, FLANNEL_SUBNET, FLANNEL_MTU, FLANNEL_IPMASQ:

 

Just got the same problem - fixed it by manually adding the file:

/run/flannel/subnet.env

FLANNEL_NETWORK=10.244.0.0/16

FLANNEL_SUBNET=10.244.0.1/24

FLANNEL_MTU=1450

FLANNEL_IPMASQ=true
