1、集群规划，如下所示：
主机名 | ip地址 | 角色 | 端口号 |
|---|---|---|---|
k8s-master | 192.168.110.133 | k8s-master | api-server:8080 |
k8s-node2 | 192.168.110.134 | k8s-node1，jenkins | tomcat:8080（跑jenkins） |
k8s-node3 | 192.168.110.135 | k8s-node1，gitlab | gitlab:80，8080 |
2、为了减轻机器压力，将之前部署地Pod节点都删除掉，如下所示：
代码语言：javascript复制 1 [root@k8s-master ~]# kubectl get all -o wide

36 [root@k8s-master ~]# 3、k8s-node3节点安装gitlab，如下所示：
首先需要下载gitlab，如下所示：
代码语言：javascript复制 1 [root@k8s-node3 ~]# wget https://mirror.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-11.9.11-ce.0.el7.x86_64.rpm

13 [root@k8s-node3 ~]# 下载完毕，进行安装，安装包比较大，安装速度也取决于硬盘的类型，如下所示：

62 Thank you for installing GitLab!
63 GitLab was unable to detect a valid hostname for your instance.
64 Please configure a URL for your GitLab instance by setting `external_url`
65 configuration in /etc/gitlab/gitlab.rb file.
66 Then, you can start your GitLab instance by running the following command:
67 sudo gitlab-ctl reconfigure
68
69 For a comprehensive list of configuration options please see the Omnibus GitLab readme
70 https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md

78 [root@k8s-node3 ~]# 安装完毕，配置gitlab（gitlab是使用ruby编写的一个工具，所以配置文件是rb的后缀），第一点是修改gitlab的访问地址，第二点是修改普罗米修斯的监控关闭掉，节省资源，如下所示：
代码语言：javascript复制1 [root@k8s-node3 ~]# vim /etc/gitlab/gitlab.rb修改内容，修改的时候建议使用域名，方便后期迁移，这里直接使用ip地址了，如下所示：
代码语言：javascript复制1 # external_url 'http://gitlab.example.com'
2 external_url 'http://192.168.110.135'
1 # prometheus_monitoring['enable'] = true
2 prometheus_monitoring['enable'] = false
修改完配置之后，需要执行命令让其生效，由于命令太长太长，这里就不贴了，如下所示：

设置完毕密码，就可以进行登录了，如下所示：
gitlab登录成功，如下所示：
gitlab创建仓库并上传代码，如下所示：
创建一个仓库，指定仓库的名称，可以对此进行描述，如下所示：
私有仓库创建成功是这个样子的，如下所示：
向下滑动，可以看到命令提示，如下所示：
此时，向仓库上传代码，上传代码，需要首先执行下面的命令，配置全局的用户，如下所示：
代码语言：javascript复制 1 [root@k8s-node3 ~]# cd /opt/

4、安装jenkins并拉取代码，需要首先安装jdk，然后安装tomcat，最后安装jenkins的。
首先安装jdk，最好去官方下载吧，根据自己需要的版本，如果官方下载慢（Oracle官方需要登录的哦！），可以找个资源然后上传到自己的服务器上，自己根据需要进行选择即可。
jdk8的下载地址：https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html。我这里直接下载好了，通过xftp上传到服务器进行安装了。

安装和启动Jenkins的方式有很多，比如常见的有 Java方式启动、Tomcat启动、Docker启动等，我在这里主要介绍下通过Tomcat的方式启动。
首先将tomcat的webapp目录下面的默认站点目录删除掉，如下所示：

8 [root@k8s-node2 webapps]# rm -rf *
9 [root@k8s-node2 webapps]# ls
10 [root@k8s-node2 webapps]# 然后将上传到服务器的jenkins.war复制到tomcat的webapp目录下面。
代码语言：javascript复制1 [root@k8s-node2 webapps]# cp ~/package/jenkins.war .
2 [root@k8s-node2 webapps]# ls
3 jenkins.war

53 [root@k8s-node2 logs]# 访问地址http://192.168.110.134:8080/，报错了，老问题了，但是呢，这次是我没有将jenkins.war解压缩正确导致的。
这次我将刚才解压缩的jenkins.war包和解压缩后的文件删除掉，如下所示：
代码语言：javascript复制1 [root@k8s-node2 webapps]# ls
2 jenkins jenkins.war
3 [root@k8s-node2 webapps]# rm -rf *
4 [root@k8s-node2 webapps]# ls然后执行关闭tomcat命令，如下所示：
代码语言：javascript复制1 [root@k8s-node2 bin]# ./shutdown.sh
2 Using CATALINA_BASE: /app/apache-tomcat-8.5.56
3 Using CATALINA_HOME: /app/apache-tomcat-8.5.56
4 Using CATALINA_TMPDIR: /app/apache-tomcat-8.5.56/temp
5 Using JRE_HOME: /usr
6 Using CLASSPATH: /app/apache-tomcat-8.5.56/bin/bootstrap.jar:/app/apache-tomcat-8.5.56/bin/tomcat-juli.jar最后使用下面的拷贝方式，将jenkins.war包改成了ROOT.war放到webapp目录下面。
代码语言：javascript复制1 [root@k8s-node2 webapps]# cd ~/package/
2 [root@k8s-node2 package]# ls
3 apache-tomcat-8.5.56 apache-tomcat-8.5.56.tar.gz jdk-8u251-linux-x64.rpm jenkins.war
4 [root@k8s-node2 package]# cp jenkins.war /app/apache-tomcat-8.5.56/webapps/ROOT.war
5 [root@k8s-node2 package]# 查看拷贝后的webapp目录下面的文件，如下所示：
代码语言：javascript复制[root@k8s-node2 webapps]# ls
ROOT.war
[root@k8s-node2 webapps]# ls
ROOT ROOT.war
[root@k8s-node2 webapps]# 启动tomcat并查看日志，并查看端口号，如下所示：
代码语言：javascript复制 1 [root@k8s-node2 bin]# ./startup.sh
2 Using CATALINA_BASE: /app/apache-tomcat-8.5.56
3 Using CATALINA_HOME: /app/apache-tomcat-8.5.56
4 Using CATALINA_TMPDIR: /app/apache-tomcat-8.5.56/temp
5 Using JRE_HOME: /usr
6 Using CLASSPATH: /app/apache-tomcat-8.5.56/bin/bootstrap.jar:/app/apache-tomcat-8.5.56/bin/tomcat-juli.jar
7 Tomcat started.

93 [root@k8s-node2 logs]# 访问地址http://192.168.110.134:8080，发现已经出现了界面了，如下所示：
如果之前安装过Jenkins，可以将之前安装过的/root/.jenkins/，放置到这个目录/root目录下面，减少安装时间。如果没有安装过程，这里执行上面的步骤即可。
根据界面的提示，到路径 /root/.jenkins/secrets/initialAdminPassword 下找出密码，然后复制填入即可。
代码语言：javascript复制1 [root@k8s-node2 package]# cat /root/.jenkins/secrets/initialAdminPassword
2 1ddc1bf154b24b34bd20a10d36f6c87f
3 [root@k8s-node2 package]# 
点击继续，出现下面的步骤，如下所示：
选择左侧安装推荐的插件，等待安装即可，出现下面的界面。
注意：安装插件有时下载速度奇慢，导致可能出现安装失败的情况，建议大家参考网上的这篇博客：https://www.cnblogs.com/hellxz/p/jenkins_install_plugins_faster.html。 我一开始没有使用，但是安装失败了，算了，还是抓紧搞一下。
default.json其实在Jenkins的工作目录中，其实就是在/root/.jenkins/updates/default.json，如下所示：
代码语言：javascript复制 1 [root@k8s-node2 .jenkins]# cd ~
2 [root@k8s-node2 ~]# cd /root/.jenkins/
3 [root@k8s-node2 .jenkins]#
4 [root@k8s-node2 .jenkins]# ls
5 config.xml identity.key.enc jenkins.install.UpgradeWizard.state jobs nodeMonitors.xml plugins secret.key secrets userContent
6 hudson.model.UpdateCenter.xml jenkins.install.InstallUtil.installingPlugins jenkins.telemetry.Correlator.xml logs nodes queue.xml.bak secret.key.not-so-secret updates users
7 [root@k8s-node2 .jenkins]# cd updates/
8 [root@k8s-node2 updates]# ls
9 default.json hudson.tasks.Maven.MavenInstaller
10 [root@k8s-node2 updates]# pwd
11 /root/.jenkins/updates
12 [root@k8s-node2 updates]# 这里为了避免搞错了，先备份一下default.json配置文件，方便后来使用。这里使用参考连接里面的第二个方法，第一个再搞错了不好办了。
代码语言：javascript复制1 [root@k8s-node2 updates]# sed -i 's/http://updates.jenkins-ci.org/download/https://mirrors.tuna.tsinghua.edu.cn/jenkins/g' default.json && sed -i 's/http://www.google.com/https://www.baidu.com/g' default.json
2 [root@k8s-node2 updates]# 重启Jenkins，安装插件试试，访问http://192.168.110.134:8080/。输入密钥解锁Jenkins点击继续。
我这里之前没有使用加速安装了，导致有两个安装失败了，其他安装速度很快很快。我这里将之前安装的删除掉了，重新安装试一下，如下所示：
代码语言：javascript复制 1 [root@k8s-node2 ~]# ll .jenkins/

33 [root@k8s-node2 ~]# 关闭tomcat，然后将tomcat的webapp下面的ROOT删除掉。建议的顺序是首先关闭tomcat，然后将tomcat的webapp下面的ROOT删除掉，然后删除掉rm -rf /root/.jenkins/，不然会有残余文件。重新安装，由于我是将Jenkins的包打成了ROOT的包了，所以直接启动tomcat即可，然后访问http://192.168.110.134:8080。输入密钥解锁Jenkins点击继续。注意：记得修改default.json配置文件哈，不然等会下载还是很慢。
下载安装很快，大概不到一分钟，这里建议直接使用加速安装插件，不然会走弯路的，如下所示：
经历了机器重启，才搞到这一步，所以一定要进行加速安装插件哦，不然瞎折腾。
创建用户登录Jenkins，上面安装完插件之后，需要设置一个管理员用户。
填写信息之后，可以选择使用admin账户继续，也可以直接选择 保存并完成，根据自己情况选择。我这里点击保存并完成，然后出现下面的界面：
点击保存并完成，出现如下界面：
点击开始使用jenkins，如下所示：
在jenkins上创建构建项目，目的就是可以拉取自己在gitlab创建的项目，jenkins想要从gitlab上拉取项目，需要一个凭据，这里生成一个密钥对，如下所示：
代码语言：javascript复制 1 [root@k8s-node2 ~]# ssh-keygen -t rsa
2 Generating public/private rsa key pair.
3 Enter file in which to save the key (/root/.ssh/id_rsa):
4 Created directory '/root/.ssh'.
5 Enter passphrase (empty for no passphrase):
6 Enter same passphrase again:
7 Your identification has been saved in /root/.ssh/id_rsa.
8 Your public key has been saved in /root/.ssh/id_rsa.pub.
9 The key fingerprint is:
10 SHA256:Adk pA0k3pYeTdy7rPW8kpG8RiXJsFKCsofEzh0Apqo root@k8s-node2
11 The key's randomart image is:

将公钥复制到ssh keys的位置，如下所示：
添加完公钥是这样的，如下所示：
现在开始配置Jenkins的凭据，如果看不到凭据，可以点下右上角的admin哦，如下所示：
然后点击用户，看到全局凭据，点击全局凭据，如下所示：
点击全局凭据，如下所示：
然后点击添加凭据，如下所示：
添加凭据，就是添加私钥，方便拉取 gitlab上面的代码，查看私钥并进行复制，如下所示：

代码语言：javascript复制1 [root@k8s-node3 feiji]# vim dockerfile
2 [root@k8s-node3 feiji]# 配置内容，如下所示：

3 # 将本目录下面的所有文件都加入进来
4 ADD . /usr/share/nginx/html如果直接执行，会将dockerfile放入进去，这里将dockerfile排除掉，如下所示：

此时项目已经构建成功了，手动构建项目是ok的。现在将刚才的命令结合jenkins进行实现，此时将这两个文件dockerfile、.dockerignore添加到我们的仓库里面去。

20 [root@k8s-node3 feiji]# 此时，来gitlab进行查看，已经发生了改变，已经将两个文件dockerfile、.dockerignore上传上去了，如下所示：
此时，gitlab已经修改了，此时需要更新Jenkins，点击项目的设置，如下所示：
代码语言：javascript复制1 # 代码拉取下来之后，执行构建镜像，构建仓库的时候写上私有仓库的地址
2 docker build -t 192.168.110.133:5000/feiji:v1 .
3 # 上传到私有仓库里面
4 docker push 192.168.110.133:5000/feiji:v1
此时，再次点击立即构建，等会查看私有仓库是否有该镜像，如下所示：
此时，发现已经构建成功了。此时存在的问题就是，如果再次点击立即构建，代码版本还是v1版本，会将之前的历史版本替换了，此时如何做到保留历史版本，这里每次立即构建的时候，需要每次更新Vx的版本，修改项目配置里面的变量。使用jenkins环境变量BUILD_ID。
这样就保证每次的版本就会更新的了，这样就解决了版本更新的问题。
此时，还有一个问题，除了版本更新的问题之外，还有一个问题就是每次更新并没有进行代码的更新，如果代码没有发生变化，此时不应该生成新的镜像。
代码语言：javascript复制1 #!/bin/bash
2 if [ $GIT_PREVIOUS_SUCCESSFUL_COMMIT == $GIT_COMMIT ];then
3 echo "no change,skip build"
4 exit 0
5 else
6 echo "git pull commit id not equals to current commit id trigger build"
7 fi
此时，尝试立即构建，但是没有进行任何更新，如下所示：
