一、安装Gitlab

1、安装并配置Gitlab

这里使用安装包的方式安装，如果需要Docker方式安装请点击这里

1.1 、下载安装包

wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-15.9.1-ce.0.el7.x86_64.rpm

1.2、安装

rpm -i gitlab-ce-15.9.1-ce.0.el7.x86_64.rpm

1.3、修改配置文件

vim /etc/gitlab/gitlab.rb 
#修改 external_url 访问路径
http://<ip>:<port>
例如我这里改为 
external_url 'http://192.168.139.184:9000'

# 修改时区
gitlab_rails['time_zone'] = 'Asia/Shanghai'

1.4、更新配置并重启

gitlab-ctl reconfigure
gitlab-ctl restart

 2、配置

2.1、修改密码

访问上面配置的external_url  http://192.168.139.184:9000/

查看默认密码

cat /etc/gitlab/initial_root_password

 默认账号是root 密码为查看到密码

右上角头像 > Perferences > Password

2.2、禁用注册功能

点击左上角三横 > Admin>Settings > General > Sign-up restrictions > 取消 Sign-up enabled > Save changes

2.3、取消头像

Settings > General > Account and limit > 取消 Gravatar enabled > Save changes

2.4、修改中文配置

Settings > Preferences > Localization > Default language > 选择简体中文 > Save changes

为当前用户设置中文，保存后刷新页面即可

 右上角用户头像 > Preferences > Localization > Language > 选择简体中文 > Save changes

2.5、配置 webhook

设置>网络>出站请求>勾选>保存

3、卸载 

# 停止服务
gitlab-ctl stop

# 卸载 rpm 软件（注意安装的软件版本是 ce 还是 ee）
rpm -e gitlab-ce

# 查看进程
ps -ef|grep gitlab 
# 干掉第一个 runsvdir -P /opt/gitlab/service log 进程

# 删除 gitlab 残余文件
find / -name *gitlab* | xargs rm -rf
find / -name gitlab | xargs rm -rf

二、安装镜像私服Harbor

1、下载安装包

#下载安装包
wget https://github.com/goharbor/harbor/releases/download/v1.10.19/harbor-offline-installer-v1.10.19.tgz

#解压
tar -zxf harbor-offline-installer-v1.10.19.tgz

 2、安装

修改配置文件

vim harbor.yml

安装

 ./install.sh

   访问http://192.168.139.184:8899/ 默认账号为admin 密码为Harbor12345

 配置docker文件，并重启docker服务 。

#查看资源
kubectl get po,svc -n kube-devops -o wide

 

 访问该端口下的服务，默认账号密码admin/admin

 

四、安装Jenkins

1、构建带有maven和sonarqube的镜像

Dockerfile

FROM jenkins/jenkins:jdk17
ADD ./apache-maven-3.9.9-bin.tar.gz /usr/local/
ADD ./sonar-scanner-cli-4.8.0.2856-linux.zip /usr/local/

USER root

WORKDIR /usr/local/
RUN unzip sonar-scanner-cli-4.8.0.2856-linux.zip
RUN mv sonar-scanner-4.8.0.2856-linux sonar-scanner-cli
RUN ln -s /usr/local/sonar-scanner-cli/bin/sonar-scanner /usr/bin/sonar-scanner

ENV MAVEN_HOME=/usr/local/apache-maven-3.9.9
ENV PATH=$JAVA_HOME/bin:$MAVEN_HOME/bin:$PATH

RUN echo "jenkins ALL=NOPASSWD: ALL" >> /etc/sudoers
USER jenkins

#构建镜像
docker build -t 192.168.139.184:8899/wsnail-harbor/jenkins-maven:jdk-17 .

#登录docker私服
docker login -uadmin 192.168.139.184:8899

#推送到仓库
docker push 192.168.139.184:8899/wsnail-harbor/jenkins-maven:jdk-17

 注意：1、该操作和docker私服在同一台服务器上

            2、请确认、etc/docker/damon.json文件配置了"insecure-registries": ["http://192.168.139.184:8899"]

3.2.5、Kubernetes
3.2.6、Config File Provider
3.2.7、Git Parameter

3.3、插件配置

3.3.1、SonarQube Scanner配置

 注意：如果不是k8s部署可以使用外网访问，ip:port

在SonarQube创建token

在jenkins中添加sonarqube的token

3.3.2、kubernetes配置

 

 

3.3.3、创建gitlab凭证

五、构建项目

1、创建gitlab的secret

后面构建项目时候需要用到

#用户名
echo root > ./username

#密码
echo xiaojie123456 > password

#创建secret
kubectl create secret generic git-user-pwd --from-file=./username --from-file=./password -n kube-devops

#查看
kubectl get  secret -n kube-devops

2、配置jenkins任务

2.1、创建流水线Job

 2.2、配置流水线

2.3、配置gitlab的Webhooks

2.4、测试构建

 2.5、测试

3、构建SpringBoot项目 

3.1、配置项目流水线

 3.2、创建镜像私服全局凭证

 3.3、创建kubeconfig文件

cat ~/.kube/config

将文件内容复制

 3.4、创建sonarqube的webhook

3.5、 cicd-demo.yaml配置文件

 3.7、Dockerfile

## 基础镜像
FROM openjdk:17-slim

## 作者
LABEL org.opencontainers.image.authors="wssnail"

## 定义参数

## 创建并进入工作目录
RUN mkdir -p /wssnail
WORKDIR /wssnail

## maven 插件构建时得到 buildArgs 种的值
COPY target/*.jar app.jar

## 设置 TZ 时区
## 设置 JAVA_OPTS 环境变量，可通过 docker run -e "JAVA_OPTS=" 进行覆盖
ENV TZ=Asia/Shanghai JAVA_OPTS="-Xms256m -Xmx256m"

## 暴露端口
EXPOSE 8080

## 容器启动命令
## CMD 第一个参数之后的命令可以在运行时被替换
CMD java ${JAVA_OPTS} -Djava.security.egd=file:/dev/./urandom -jar app.jar
