開發(fā)離不開項目的部署二驰，運維每强，因此為了以后的開發(fā)便利，我最近學(xué)習(xí)了下服務(wù)的自運維娇掏，現(xiàn)在總結(jié)一下
參考：https://my.oschina.net/yimingkeji/blog/2878371
技術(shù)
Jenkins+docker+git+Gitee 部署SpringBoot項目
環(huán)境
- Win10
- 虛擬機：VMware
- 系統(tǒng)：centos7
操作流程
1.安裝虛擬機呕寝，配置centos系統(tǒng)，聯(lián)通網(wǎng)絡(luò)
2.配置Java環(huán)境
3.下載婴梧，安裝下梢，配置jenkins
1）Jenkins的介紹
Jenkins是一個廣泛用于持續(xù)構(gòu)建的可視化web工具，可用于自動化與構(gòu)建塞蹭、測試孽江、交付或部署軟件相關(guān)的各種任務(wù)。
2）看下Jenkins的工作流程
- 我們在本地開發(fā)項目番电。記得加上dcoker的依賴和Dockerfile的配置（后面說）竟坛。然后通過本地git提交到碼云（Github）。
- 這時碼云上的項目中配置鉤子程序（Webhooks）钧舌。當(dāng)我們在本地push的時候觸發(fā)鉤子。
這個URL的地址要觸發(fā)Jenkis(后面介紹)

- Jenkins接收到通知以后涎跨，會調(diào)用虛擬機上的git洼冻。將遠(yuǎn)程碼云倉庫的項目pull到服務(wù)器上
- 接下來的工作中心就在Jenkins上。根據(jù)配置（后面詳細(xì)說）隅很，將項目用服務(wù)器上mvn打成jar包
- 利用docker結(jié)合項目的dockerfile撞牢，打包成docker鏡像，然后啟動即可叔营。（具體配置看后面）
3）Jenkins的下載和安裝
看參考即可
不同的是我沒有安裝到tomcat下面屋彪，隨tomcat啟動，而是直接安裝linux中绒尊，然后設(shè)置啟動
這可以百度下
4.配置docker
- 首先是插件的安裝畜挥，可以看參考，會遇到無法連接到外網(wǎng)服務(wù)器的問題婴谱，百度解決即可
- 進(jìn)去后蟹但，首先全局配置，-》看參考 配置maven谭羔、JDK华糖、Docker、git
這些都需要安裝到服務(wù)器上瘟裸，git還需生成私鑰客叉，公鑰。公鑰放到碼云遠(yuǎn)程倉庫，私鑰放到Jenkins上兼搏，使得通過Jenkin利用git將代碼拉到服務(wù)器上卵慰。
- 安裝docker
- Springboot項目
項目地址：https://gitee.com/yimingkeji/docker-springboot
docker依賴
<!-- Docker maven plugin start -->
<plugin>
<groupId>com.spotify</groupId>
<artifactId>docker-maven-plugin</artifactId>
<version>0.4.13</version>
<configuration>
<imageName>${project.artifactId}</imageName><!--[a-z 0-9] 不然docker:build會報錯-->
<dockerDirectory>${project.basedir}/src/main/docker</dockerDirectory>
<!--dockerfile的地址-->
<resources>
<resource>
<targetPath>/</targetPath>
<directory>${project.build.directory}</directory>
<include>${project.build.finalName}.jar</include>
</resource>
</resources>
</configuration>
</plugin>
<!-- Docker maven plugin end -->
Dockerfile內(nèi)容：
FROM hub.c.163.com/dwyane/openjdk:8
VOLUME /tmp
ADD docker-test-0.0.1-SNAPSHOT.jar app.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
EXPOSE 8081
dockerfile的jar包的名字要和項目的名字保持一致
<groupId>com.wuhen</groupId>
<artifactId>docker-test</artifactId>
<version>0.0.1-SNAPSHOT</version>
然后上傳到自己的碼云遠(yuǎn)程倉庫
5.使用Jenkins部署項目到docker
看參考
其中
第一次執(zhí)行shell 添加shell：
#!/bin/bash -il
mvn docker:build
echo "當(dāng)前docker 鏡像："
docker images | grep docker-test
echo "啟動容器----->"
docker run --name dockertest -p 8081:8081 -d docker-test
echo "啟動服務(wù)成功！"
項目構(gòu)建成功后再次構(gòu)建shell有所改變
#!/bin/bash -il
# 先刪除之前的容器
echo "remobe old container"
docker ps -a | grep dockertest | awk '{print $1}'| xargs docker rm -f
# 刪除之前的鏡像
echo "romove old image"
docker rmi docker-test
# 構(gòu)建鏡像
mvn docker:build
# 打印當(dāng)前鏡像
echo "current docker images"
docker images | grep docker-test
# 啟動容器
echo "start container"
docker run --name dockertest -p 8081:8081 -d docker-test
# 打印當(dāng)前容器
echo "current container"
docker ps -a | grep dockertest
echo "star service success!"
這個容器端口映射：項目的啟動端口好為8081向族，映射到外部服務(wù)器端口為8081（可以固定呵燕。也可以隨機），所以在外部瀏覽器訪問IP：8081,即映射到項目上件相，添加路徑即可訪問

可以結(jié)合參考和我的文章選擇自己合適的配置路線再扭，與其說是寫總結(jié)，也是結(jié)合自己弟參考文章的補充
