今天嘗試在虛擬機(jī)安裝k8s集群，用sleaos安裝
1.安裝sealos

# 下載并安裝sealos, sealos是個(gè)golang的二進(jìn)制工具，直接下載拷貝到bin目錄即可, release頁(yè)面也可下載
wget -c https://sealyun-home.oss-cn-beijing.aliyuncs.com/sealos/latest/sealos && \
    chmod +x sealos && mv sealos /usr/bin 

# 下載離線資源包
wget -c https://sealyun.oss-cn-beijing.aliyuncs.com/05a3db657821277f5f3b92d834bbaf98-v1.22.0/kube1.22.0.tar.gz

2.運(yùn)行命令

sealos init --passwd 'Lins!@34' \
    --master 192.168.56.5  --node 192.168.56.6 \
    --pkg-url /root/kube1.21.1.tar.gz \
    --version v1.21.1

3.啟動(dòng)后發(fā)現(xiàn)node一直是notready狀態(tài)

[root@master01 1.8+]# kubectl  get nodes
NAME       STATUS     ROLES                  AGE     VERSION
master01   NotReady   control-plane,master   9m11s   v1.21.1
master02   NotReady   <none>                 8m38s   v1.21.1

一開(kāi)始以為是metrics-server沒(méi)裝導(dǎo)致，后一想不對(duì)，metrics-server只會(huì)導(dǎo)致kubectl top 失效

4.檢查了kubelet 日志，一開(kāi)始以為calico問(wèn)題，檢查了下calico運(yùn)行正常

5月 12 18:43:11 master02 kubelet[9500]: E0512 18:43:11.339414    9500 kubelet.go:2211] "Container runtime network not ready" networkReady="NetworkReady=false reason:NetworkPluginNotReady message:Network plugin returns error: cni plugin not initialized"

5.試了網(wǎng)上一圈，比如重新生成ssl，最終解決重啟了容器運(yùn)行時(shí)進(jìn)程，比如docker或者containerd,我這邊是containerd,問(wèn)題解決。記錄下，其實(shí)還沒(méi)明白什么原因。

[root@master01 1.8+]# systemctl restart containerd
[root@master01 1.8+]# kubectl  get nodes
NAME       STATUS   ROLES                  AGE   VERSION
master01   Ready    control-plane,master   12m   v1.21.1
master02   Ready    <none>                 12m   v1.21.1
