鲲鹏云服务器上安装docker-云社区-华为云 (huaweicloud.com)
[root@master ~]# cat /etc/os-release

这里我下载的版本是docker-18.09.3.tag
wget -c https://download.docker.com/linux/static/stable/aarch64/docker-18.09.3.tgz
docker 安装包地址：https://download.docker.com/linux/static/stable
- 解压，然后将docker目录下文件拷贝到/usr/bin里
tar -xf docker-18.09.3.tgz
mv docker/* /usr/bin/
- 配置system服务
- 在github对应分支的contrib/init/systemd/ 下面，提供了对应的docker.service以及docker.socket文件，可以直接拷贝到本地文件使用：
对应链接：https://github.com/docker/engine/tree/19.03/contrib/init/systemd
新建编辑docker.service文件，将https://github.com/docker/engine/edit/19.03/contrib/init/systemd/docker.service这个链接内容拷贝并保存：
vi /lib/systemd/system/docker.service

- 新建docker用户和组
groupadd docker
useradd docker -g docker
- 启动docker服务
systemctl daemon-reload
systemtl start docker
- 查看docker版本

在银河麒麟操作系统安装k8s又让我老烦了，在网上各种查询网络源，最后还是在华为云上找到了解决办法
网址链接：https://bbs.huaweicloud.com/forum/forum.php?mod=viewthread&tid=84043&ordertype=2&page=1
注意：这里需要注意docker和K8s的版本兼容问题，这里我的k8s版本1.18.2的
添加网络源
vi /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes Repo
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-aarch64/
gpgcheck=0
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg
enabled=1
- 安装k8s
yum install -y kubelet-1.18.2 kubeadm-1.18.2 kubectl-1.18.2
systemctl enable kubelet && sudo systemctl start kubelet
初始化k8s添加集群
这里的v1.18.2是k8s安装的版本，这里我的版本是1.18.2,10.15.15.187这里是要初始化的主节点IP地址
sudo kubeadm init --image-repository registry.aliyuncs.com/google_containers --kubernetes-version v1.18.2 --apiserver-advertise-address 10.15.15.187 --pod-network-cidr=10.244.0.0/16 --token-ttl 0
初始化完成之后会有node状态为NotReady需要下载网络插件就好了
下载calico网络插件
wget https://kuboard.cn/install-script/calico/calico-3.13.1.yaml
运行插件
kubectl apply -f calico-3.13.1.yaml
最后稍微等待一下，node状态就会变为Ready，如果始终没有Ready使用kubectl查看一下网络插件的pod状态和原因
查看所有pod的命令
kubectl -n kube-system get pod
kubectl get pod --all-namespaces
