準(zhǔn)備工作
請(qǐng)注意開(kāi)始前工作確定各個(gè)軟件版本情況，本文章要想閱讀比較舒服請(qǐng)還得有些Go開(kāi)發(fā)經(jīng)驗(yàn)
- CentOS 7.9
- KubeKey v1.21
- KubeSphere v3.2.1
Docker 和 Kubernetes 根據(jù)支持進(jìn)行選擇：
獲取支持可以通過(guò)如下命令：
./kk version --show-supported-k8s
v1.15.12
v1.16.8
v1.16.10
v1.16.12
v1.16.13
v1.17.0
v1.17.4
v1.17.5
v1.17.6
v1.17.7
v1.17.8
v1.17.9
v1.18.3
v1.18.5
v1.18.6
v1.18.8
v1.19.0
v1.19.8
v1.19.9
v1.20.4
v1.20.6
v1.20.10
v1.21.4
v1.21.5 (我測(cè)試選擇的版本)
v1.22.1
開(kāi)始前必須準(zhǔn)備
請(qǐng)認(rèn)真閱讀對(duì)應(yīng)官方的幾個(gè)文檔說(shuō)明
Documentation (kubesphere.com.cn)
根據(jù)自己的安裝選擇進(jìn)行閱讀，注意準(zhǔn)備干凈的機(jī)器環(huán)境
在開(kāi)始進(jìn)行安裝前可以不安裝Docker kk 都會(huì)幫解決
Dingtalk_20220114133617.jpg
依賴說(shuō)明，在剛安裝好的 CentOS機(jī)器上會(huì)提示：socat付呕、conntrack 必須條件要安裝
yum -y install socat conntrack-tools
關(guān)閉防火墻
systemctl stop firewalld
systemctl disable firewalld
單機(jī)安裝
https://kubesphere.com.cn/docs/quick-start/all-in-one-on-linux/
單機(jī)安裝一般沒(méi)有什么坑稚字，一般比較順暢。
./kk create cluster --with-kubesphere v3.2.1
多機(jī)安裝
多節(jié)點(diǎn)安裝 (kubesphere.com.cn)
./kk create cluster -f sample.yaml --with-kubesphere v3.2.1
遇到的坑
不部署 KubeSphere 胡桨，只是部署 Kubernetes
1.根據(jù)文檔進(jìn)行如下命令進(jìn)行部署扣孟，多次發(fā)現(xiàn) KubeSphere 一直沒(méi)有部署成功烫堤。Docker ps 中進(jìn)程也少
./kk create cluster -f sample.yaml
部署中提示到 Congratulations! Installation is successful. 進(jìn)行技術(shù)
經(jīng)過(guò)源碼查證后發(fā)下如下：
- 查看 Congratulations! Installation is successful. 出現(xiàn)位置
mgr.Logger.Infoln("Congratulations! Installation is successful.")
網(wǎng)上看發(fā)現(xiàn)
if mgr.KsEnable && !noNetworkPlugin
``
執(zhí)行 else 才會(huì)進(jìn)行打印
2.確認(rèn)網(wǎng)絡(luò)是否啟動(dòng) noNetworkPlugin
```golang
noNetworkPlugin := mgr.Cluster.Network.Plugin == "" || mgr.Cluster.Network.Plugin == "none"
查看代碼發(fā)現(xiàn)和網(wǎng)絡(luò)插件有關(guān)，已經(jīng)配置啦
network:
plugin: calico
kubePodsCIDR: 10.233.64.0/18
kubeServiceCIDR: 10.233.0.0/18
3.推出只有 mgr.KsEnable 凤价，然后鸽斟，本地進(jìn)行代碼調(diào)試發(fā)現(xiàn)。執(zhí)行結(jié)果確實(shí)是 false 是不是有些坑利诺，因此開(kāi)始尋找 KsEnable 如何賦值
// pkg\util\executor\executor.go
mgr.KsEnable = executor.Cluster.KubeSphere.Enabled
// pkg\cluster\install\install.go
// Execute executes the tasks based on the parameters in the Manager.
func Execute(executor *executor.Executor) error {
mgr, err := executor.CreateManager()
if err != nil {
return err
}
return ExecTasks(mgr)
}
// 找到出現(xiàn)位置啦 ksEnabled
// CreateCluster is used to create cluster based on the given parameters or configuration file.
func CreateCluster(clusterCfgFile, k8sVersion, ksVersion string, logger *log.Logger, ksEnabled, verbose, skipCheck, skipPullImages, inCluster, deployLocalStorage bool, downloadCmd, containerManager string) error
// 找到啦富蓄，結(jié)果知道如果執(zhí)行啦
// cmd
clusterCmd.Flags().BoolVarP(&opt.Kubesphere, "with-kubesphere", "", false, "Deploy a specific version of kubesphere (default v3.2.0)")
最終執(zhí)行命令行為
./kk create cluster -f sample.yaml --with-kubesphere v3.2.1
