Today, the editor will share with you the relevant knowledge points about how to install kubernetes CNI. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

Environment introduction

When we install kubernetes, we do not install CNI. If the sealyun offline package is used, modify the kube/conf/master.sh

Only the following can be left:

[root@helix105 shell] # cat master.sh kubeadm init-- config.. / conf/kubeadm.yamlmkdir ~ / .kubecp / etc/kubernetes/admin.conf ~ / .kube/configkubectl taint nodes-- all node-role.kubernetes.io/master-

Clear the CNI related directories:

Rm-rf / opt/cni/bin/*rm-rf / etc/cni/net.d/*

Start kubernetes, and if you have already installed it, then kubeadm reset:

Cd kube/shell & & sh init.sh & & sh master.sh

At this point, your node is notready, and your coredns cannot be assigned an address:

[root@helix105 shell] # kubectl get pod-n kube-system-o wideNAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATEScoredns-5c98db65d4-5fh7c 0 Pending 0 54s coredns-5c98db65d4 -dbwmq 0 kube-controller-manager-helix105.hfa.chenqian 1 Pending 0 54s kube-controller-manager-helix105.hfa.chenqian 1 Running 0 19s 172.16.60.105 helix105.hfa.chenqian kube-proxy-k74ld 1 Running 0 54s 172.16.60.105 helix105.hfa.chenqian kube-scheduler-helix105.hfa.chenqian 1 Running 0 14s 172.16.60.105 helix105.hfa.chenqian [root@helix105 shell] # kubectl get nodeNAME STATUS ROLES AGE VERSIONhelix105.hfa.chenqian NotReady master 86s v1.15.0 install CNI

Create a CNI profile

$mkdir-p / etc/cni/net.d$ cat > / etc/cni/net.d/10-mynet.conf
