ARM架构部署Kubernetes

基础软件源推荐用中科大的速度还可以

 

 

Kubernetes初始化文件

 

cat init-config.yaml 
apiVersion: kubeadm.k8s.io/v1beta2

docker部署按照官网部署即可

 

kubernetes ARM源用阿里的

 

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

cat <<EOF >/etc/apt/sources.list.d/kubernetes.list
deb https://mirrors.aliyun.com/kubernetes/apt/ kubernetes-xenial main
EOF

 

安装kubernetes部署工具以及相关组件软件

apt install kubeadm=1.18.0-00 kubectl=1.18.0-00 kubelet=1.18.0-00 

 

错误以及处理方式

etcd那个可以忽略外部部署重启忘记开服务了，可以设置成开机自动启动。至于memory那个需要用cgroup去管理
