Kubernetes之OVS CNI之Antrea的实践

ubuntu18.04，

切换到阿里云的源，

sudo mv /etc/apt/sources.list /etc/apt/sources.list.bak，

sudo vim /etc/apt/sources.list，

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

sudo apt update，sudo apt dist-upgrade，

安装OVS，

sudo apt install openvswitch-switch openvswitch-common，

安装Docker，

sudo apt install docker.io，

sudo systemctl enable docker，

sudo gpasswd -a ubuntu docker，

newgrp docker，

安装Kubernetes，

curl https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | apt-key add -，

sudo vim /etc/apt/sources.list.d/kubernetes.list，

deb https://mirrors.aliyun.com/kubernetes/apt/ kubernetes-xenial main

sudo apt update，

sudo apt install kubelet=1.19.16-00 kubeadm=1.19.16-00 kubectl=1.19.16-00，

sudo swapoff -a，

sudo kubeadm init --pod-network-cidr=10.244.0.0/16 --image-repository registry.aliyuncs.com/google_containers --kubernetes-version=v1.19.16，

mkdir -p $HOME/.kube，

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

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

kubectl taint nodes --all node-role.kubernetes.io/master-，

安装Antrea，

docker pull docker.mirrors.ustc.edu.cn/antrea/antrea-ubuntu:latest，

wget https://raw.githubusercontent.com/antrea-io/antrea/main/build/yamls/antrea.yml，

kubectl apply -f antrea.yml，完成，就这么简单。
