0.準(zhǔn)備工作

這次的安裝部署是在arm64上面執(zhí)行的，板子為RK3328，系統(tǒng)為Ubuntu16.04。

主要有一個(gè)Master和兩個(gè)Node，主要需要安裝以下的組件：

角色	IP	組件
k8s-master	172.16.32.10	etcd,apiserver,controller-manager,scheduler,flannel
k8s-node1	172.16.32.11	kubelet,kube-proxy,flannel,docker
k8s-node2	172.16.32.12	kubelet,kube-proxy,flannel,docker

這里Master的組件是：kube-apiserver,kube-controller-manager,kube-scheduler

提前下載好相關(guān)的組件
- etcd-v3.3.5-linux-arm64.tar.gz
- flannel-v0.10.0-linux-arm64.tar.gz
- kubernetes-node-linux-arm64.tar.gz
- kubernetes-server-linux-arm64.tar.gz
具體下載到GitHub上下載，如果不知道網(wǎng)址，可以直接搜 xxx release（比如etcd release），一般出來第一個(gè)就是了，然后選擇對應(yīng)版本下載

1.部署Master

部署前的初始化
- 首先以root用戶執(zhí)行以下動作
  1. 關(guān)閉防火墻ufw disable
  2. 安裝ntp（如果沒有安裝) sudo apt-get install ntp
  3. 添加主機(jī)名和IP到/etc/hosts
```
172.16.32.10 k8s-master
172.16.32.11 k8s-node1
172.16.32.12 k8s-node2
```
  4. 新建一個(gè)k8s-master用戶，并且賦予root權(quán)限
```
useradd -m -d /home/k8s-master -s /bin/bash k8s-master
 sudo sed -i -r '/root.*ALL=$ALL.*ALL/a   \k8s-master  ALL=\(ALL$ NOPASSWD: ALL' /etc/sudoers
```
  5. 切換到k8s-master用戶 su k8s-master
- 切換到k8s-master用戶執(zhí)行以下動作
  1. 創(chuàng)建文件夾，用來保存bin和組件的配置文件
    
    sudo mkdir -p ~/kubernetes/bin && sudo mkdir ~/kubernetes/cfg
  2. 設(shè)置環(huán)境變量，因?yàn)槲覀兊亩M(jìn)制放在自己指定的路徑，加入環(huán)境變量就方便使用。
    
    echo "export PATH=\$PATH:/home/k8s-master/kubernetes/bin" >> ~/.bashrc
    
    source ~/.bashrc
安裝ETCD
- 解壓etcd-v3.3.5-linux-arm64.tar.gz
  
  sudo tar -zxvf etcd-v3.3.5-linux-arm64.tar.gz
- 復(fù)制解壓目錄下的etcd，etcdctl到~/kubernetes/bin
  
  sudo cp etcd-v3.3.5-linux-arm64/etcd* ~/kubernetes/bin
- 創(chuàng)建etcd配置文件 sudo vi ~/kubernetes/cfg/ectd.cfg
```
ETCD_NAME="default"
ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
ETCD_LISTEN_CLIENT_URLS="http://0.0.0.0:2379"
ETCD_ADVERTISE_CLIENT_URLS="http://0.0.0.0:2379"
```
  注意這里在啟動etcd服務(wù)之前，需要先創(chuàng)建好/var/lib/etcd目錄，存放etcd的數(shù)據(jù)
- 創(chuàng)建etcd服務(wù)文件 sudo vi /lib/systemd/system/etcd.service
```
[Unit]
Description=Etcd Server
After=network.target

ExecStart=/bin/bash -c "GOMAXPROCS=\$(nproc) /home/k8s-master/kubernetes/bin/etcd"
Type=notify

[Install]
WantedBy=multi-user.target
```
  注意，這里需要加上一句Environment=ETCD_UNSUPPORTED_ARCH=arm64，因?yàn)楫?dāng)前etcd要支持arm必須這樣子，否則etcd無法啟動。
- 啟動ETCD服務(wù)
```
sudo systemctl daemon-reload
sudo systemctl start etcd
sudo systemctl enable etcd
```
  可以通過systemctl status etcd 查看ETCD的狀態(tài)，如果出錯(cuò)，可以看log日志：/var/log/syslog
- 創(chuàng)建ETCD網(wǎng)絡(luò)
  
  etcdctl set /coreos.com/network/config "{\"Network\":\"10.1.0.0/16\",\" Backend \"{\"Type\":\"vxlan\"}}"
  
  如果不指定Backend類型為vxlan,在安裝flannel時(shí)會報(bào)錯(cuò)：不支持UDP Backend,因?yàn)閒lannel默認(rèn)Backend是UDP，arm不支持，所以在創(chuàng)建ETCD網(wǎng)絡(luò)的時(shí)候需要指定Backend類型

安裝Master三個(gè)重要組件：kube-apiserver,kube-controller-manager,kube-scheduler

解壓kubernetes-server-linux-arm64.tar.gz

sudo tar -zxvf kubernetes-server-linux-arm64.tar.gz -C kubernetes-server-linux-arm64
復(fù)制二進(jìn)制bin文件到 ~/kubernetes/bin

sudo cp kubernetes-server-linux-arm64/kubernetes/server/bin/kube-apiserver ~/kubernetes/bin

sudo cp kubernetes-server-linux-arm64/kubernetes/server/bin/kube-controller-manager ~/kubernetes/bin

sudo cp kubernetes-server-linux-arm64/kubernetes/server/bin/kube-scheduler ~/kubernetes/bin

安裝kube-apiserver

添加kube-apisever配置文件

sudo vi ~/kubernetes/cfg/kube-apiserver

sudo systemctl daemon-reload
sudo systemctl start docker
sudo systemctl enable docker

2.部署Node

Node的部署與Master大致一樣，都是添加配置文件，服務(wù)文件，啟動服務(wù)。

同樣在部署前需要做些初始化
- 關(guān)閉防火墻ufw disable
- 安裝ntp（如果沒有安裝) sudo apt-get install ntp
- 添加主機(jī)名和IP到/etc/hosts
```
172.16.32.10 k8s-master
172.16.32.11 k8s-node1
172.16.32.12 k8s-node2
```
- 新建一個(gè)k8s-node1用戶，并且賦予root權(quán)限
```
useradd -m -d /home/k8s-node1 -s /bin/bash k8s-node1
sudo sed -i -r '/root.*ALL=$ALL.*ALL/a   \k8s-node1  ALL=\(ALL$ NOPASSWD: ALL' /etc/sudoers
```
- 切換到k8s-node1 su k8s-node1
- 切換到k8s-node1用戶執(zhí)行以下動作
  - 創(chuàng)建文件夾，用來保存bin和組件的配置文件
    
    sudo mkdir -p ~/kubernetes/bin && sudo mkdir ~/kubernetes/cfg

安裝kubelet,kube-proxy

解壓kubernetes-node-linux-arm64.tar.gz

sudo tar -zxvf kubernetes-node-linux-arm64.tar.gz kubernetes-node-linux-arm64
復(fù)制二進(jìn)制bin到~/kubernetes/bin

sudo cp kubernetes-node-linux-arm64/kubernetes/node/bin/kubelet ~/kubernetes/bin

sudo cp kubernetes-node-linux-arm64/kubernetes/node/bin/kube-proxy ~/kubernetes/bin

安裝kubelet

添加配置文件

sudo vi ~/kubernetes/cfg/kubelet.kubeconfig

apiVersion: v1
kind: Config
clusters:
  - cluster:
      server: http://172.16.32.10:8080/
    name: local
contexts:
  - context:
      cluster: local
    name: local
current-context: local

sudo vi ~/kubernetes/cfg/kubelet

# --logtostderr=true: log to standard error instead of files
KUBE_LOGTOSTDERR="--logtostderr=true"

#  --v=0: log level for V logs
KUBE_LOG_LEVEL="--v=4"

# --address=0.0.0.0: The IP address for the Kubelet to serve on (set to 0.0.0.0 for all interfaces)
NODE_ADDRESS="--address=172.16.32.11"

# --port=10250: The port for the Kubelet to serve on. Note that "kubectl logs" will not work if you set this flag.
NODE_PORT="--port=10250"

# --hostname-override="": If non-empty, will use this string as identification instead of the actual hostname.
NODE_HOSTNAME="--hostname-override=ubuntu-node1"

# Path to a kubeconfig file, specifying how to connect to the API server.
KUBELET_KUBECONFIG="--kubeconfig=~/kubernetes/cfg/kubelet.kubeconfig"
#KUBELET_KUBECONFIG="--api-servers=http://${MASTER_ADDRESS}:8080"

# --allow-privileged=false: If true, allow containers to request privileged mode. [default=false]
KUBE_ALLOW_PRIV="--allow-privileged=false"

# DNS info
KUBELET__DNS_IP="--cluster-dns=169.169.0.2"
KUBELET_DNS_DOMAIN="--cluster-domain=cluster.local"

KUBELET_SWAP="--fail-swap-on=false"

KUBELET_ARGS="--pod_infra_container_image=hub.c.163.com/allan1991/pause-amd64:3.0"

在kubernetes1.10版本中，KUBELET_KUBECONFIG修改為了用一個(gè)yaml的配置文件，而不再是以前的指定--api-server的方式，需要相應(yīng)更改過來，否則kubelet無法啟動。

#  --v=0: log level for V logs
KUBE_LOG_LEVEL="--v=4"

# --hostname-override="": If non-empty, will use this string as identification instead of the actual hostname.
NODE_HOSTNAME="--hostname-override=k8s-node1"

# --master="": The address of the Kubernetes API server (overrides any value in kubeconfig)
KUBE_MASTER="--master=http://172.16.32.10:8080"

啟動服務(wù)

sudo systemctl daemon-reload
sudo systemctl start kube-proxy
sudo systemctl enable kube-proxy

安裝flannel

安裝方法和在Master中安裝的一樣，可以參考上面進(jìn)行安裝。

3.安裝過程遇到過的問題記錄

failed to start containermanager system validation failed - following cgroup subsystem not mounted:[memory]

解決方法：

修/etc/default/grub：

添加：GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"

更新：update-grub

重啟：sudo systemctl reboot -i

如果grub沒有安裝，可以先安裝：

sudo apt install grub-efi-arm64 grub-efi-arm64-bin grub2-common
etcdmain: etcd on unsupported platform without ETCD_UNSUPPORTED_ARCH=arm64 set

解決方法：

在etcd的服務(wù)文件中加上一句：

Environment=ETCD_UNSUPPORTED_ARCH=arm64 #此行必須添加
UDP backend is not supported on this architecture

解決方法:

由于flannel預(yù)設(shè)的backend type是udp，但arm64不支持，所以在etcd中需要指定backend參數(shù)：

etcdctl set /coreos.com/network/config "{\"Network\":\"10.1.0.0/16\",\" Backend \"{\"Type\":\"vxlan\"}}"
