Kubernetes集群部署之Flannel_kube1.23.0的版本中kube-flannel怎么安装

1.为Flannel生成证书:
复制代码
[root@k8s-master ~]# cd /usr/local/src/ssl/
[root@k8s-master ssl]# cat > flanneld-csr.json <<EOF
{
  "CN": "flanneld",
  "hosts": [],
  "key": {
    "algo": "rsa",
    "size": 2048
  },
  "names": [
    {
      "C": "CN",
      "ST": "BeiJing",
      "L": "BeiJing",
      "O": "k8s",
      "OU": "System"
    }
  ]
}
 
EOF
 
复制代码
2.生成证书
[root@k8s-master ssl]# cfssl gencert -ca=/opt/kubernetes/ssl/ca.pem \
   -ca-key=/opt/kubernetes/ssl/ca-key.pem \
   -config=/opt/kubernetes/ssl/ca-config.json \
   -profile=kubernetes flanneld-csr.json | cfssljson -bare flanneld
   
3.分发证书文件
[root@k8s-master ssl]# cp flanneld*.pem /opt/kubernetes/ssl/
[root@k8s-master ssl]# scp flanneld*.pem 10.200.3.106:/opt/kubernetes/ssl/
[root@k8s-master ssl]# scp flanneld*.pem 10.200.3.107:/opt/kubernetes/ssl/
4.下载Flannel软件包
[root@k8s-master ssl]# cd /usr/local/src
[root@k8s-master src]# wget \
 https://github.com/coreos/flannel/releases/download/v0.10.0/flannel-v0.10.0-linux-amd64.tar.gz
[root@k8s-master src]# tar zxf flannel-v0.10.0-linux-amd64.tar.gz
[root@k8s-master src]# cp flanneld mk-docker-opts.sh /opt/kubernetes/bin/
分发文件到node节点
[root@k8s-master src]# scp flanneld mk-docker-opts.sh 10.200.3.106:/opt/kubernetes/bin/
[root@k8s-master src]# scp flanneld mk-docker-opts.sh 10.200.3.107:/opt/kubernetes/bin/
分发对应脚本到/opt/kubernetes/bin目录下
复制代码
[root@k8s-master src]# cd /usr/local/src/kubernetes/cluster/centos/node/bin/
[root@k8s-master bin]# cp remove-docker0.sh /opt/kubernetes/bin/
[root@k8s-master bin]# scp remove-docker0.sh 10.200.3.106:/opt/kubernetes/bin/
remove-docker0.sh
