使用Jenkins、Docker、GitLab 部署SpringBoot項目
安裝Jenkins
下載 Jenkins RPM包 java
wget https://pkg.jenkins.io/redhat/jenkins-2.197-1.1.noarch.rpm複製代碼
安裝 Jenkins mysql
rpm -ivh jenkins-2.197-1.1.noarch.rpm複製代碼
啓動Jenkins nginx
sudo service jenkins start複製代碼
解鎖git
這裏提示解鎖Jenkins，複製 /Users/Shared/Jenkins/Home/secrets/initialAdminPassword文件內容到頁面redis
cat /Users/Shared/Jenkins/Home/secrets/initialAdminPassword
複製代碼
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://pvo5vonp.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
複製代碼
設置用戶spring
解鎖成功後，跳轉到設置用戶頁面 
sql
這裏設置 admin / admindocker
安裝默認插件shell
而後提示安裝插件，選擇默認的安裝，等待安裝完成。有些插件可能安裝失敗，提示要求升級最新版本Jenkins，升級成功後能夠安裝成功。apache
全局配置
點擊 >系統設置>全局工具配置
配置maven、JDK、Docker、git
Dockerfile內容：
#FROM openjdk:8-jdk-alpine
FROM hub.c.163.com/dwyane/openjdk:8
VOLUME /tmp
ADD docker-springboot-1.0-SNAPSHOT.jar app.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
複製代碼
而後上傳到本身的git地址
使用Jenkins部署項目到Docker
在jenkins頁面添加自由風格的軟件項目
在源碼管理裏添加git倉庫和用戶名、密碼配置，而且選擇代碼分支（這裏是master）
配置JenkinsSSH免密訪問GitLab
ssh-keygen -t rsa -C "youmail@mail.com" -b 4096
cat ~/.ssh/id_rsa.pub,複製添加到GitLab的SSH祕鑰
設置Jenkins啓動爲root，解決拉代碼權限問題
vim /etc/sysconfig/jenkins，修改JENKINS_USER="root"
在構建步驟中，添加2個步驟
1.頂級maven 選擇maven版本（上面的全局配置中配的maven），添加maven打包命令
clean install -Dmaven.test.skip=true
複製代碼2.
執行shell 添加shell：
/opt/apache-maven-3.2.5/bin/mvn docker:build
echo "當前docker 鏡像："
docker images | grep dockerspringboot
echo "啓動容器----->"
docker run -p 8001:8001 -d dockerspringboot
echo "啓動服務成功！"
複製代碼
執行構建並啓動服務
上面配置完成後，到Jenkins主頁，選擇配置好的項目，菜單中點擊當即構建
看到左邊菜單裏有執行的進度條，點進去後會看到執行日誌
構建中 在工做空間 /Users/yangzhenlong/.jenkins/workspace/docker-springboot 中

複製代碼
而後瀏覽器訪問 localhost:8080
改造shell腳本
若是下次構建該項目的時候，docker鏡像和服務已存在，須要先刪除鏡像和服務
# 先刪除以前的容器
echo "remobe old container"
docker ps -a | grep dockerspringboot | awk '{print $1}'| xargs docker rm -f
# 刪除以前的鏡像
echo "romove old image"
docker rmi dockerspringboot
# 構建鏡像
mvn docker:build
# 打印當前鏡像
echo "current docker images"
docker images | grep dockerspringboot
# 啓動容器
echo "start container"
docker run -p 8001:8001 -d dockerspringboot
# 打印當前容器
echo "current container"
docker ps -a | grep dockerspringboot
echo "star service success!"
