--!--| This is the configuration file for Maven. It can be specified at two levels:|| 1. User Level. This settings.xml file provides configuration for a single user,| and is normally provided in ${user.home}/.m2/settings.xml.|| NOTE: This location can be overridden with the CLI option:|| -s /path/to/user/settings.xml|| 2. Global Level. This settings.xml file provides configuration for all Maven| users on a machine (assuming theyre all using the same Maven| installation).

Profiles provided in the settings.xml are intended to provide local machine-| specific paths and repository locations which allow the build to work in the local environment.|| For example, if you have an integration testing plugin - like cactus - that needs to know where| your Tomcat instance is installed, you can provide a variable here such that the variable is| dereferenced during the build process to configure the cactus plugin.|| As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles| section of this document (settings.xml) - will be discussed later. Another way essentially| relies on the detection of a property, either matching a particular value for the property,| or merely testing its existence. Profiles can also be activated by JDK version prefix, where a| value of 1.4 might activate a profile when the build is executed on a JDK version of 1.4.2_07.| Finally, the list of active profiles can be specified directly from the command line.|| NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact| repositories, plugin repositories, and free-form properties to be used as configuration| variables for plugins in the POM.||--profiles!-- profile| Specifies a set of introductions to the build process, to be activated using one or more of the| mechanisms described above. For inheritance purposes, and to activate profiles via activatedProfiles/| or the command line, profiles have to have an ID that is unique.|| An encouraged best practice for profile identification is to use a consistent naming convention| for profiles, such as env-dev, env-test, env-production, user-jdcasey, user-brett, etc.| This will make it more intuitive to understand what the set of introduced profiles is attempting| to accomplish, particularly when you only have a list of profile ids for debug.|| This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo.profileidjdk-17/idactivationjdk17/jdk/activationrepositoriesrepositoryidjdk17/idnameRepository for JDK 17 builds/nameurlhttp://www.myhost.com/maven/jdk17/urllayoutdefault/layoutsnapshotPolicyalways/snapshotPolicy/repository/repositories/profile--!--| Here is another profile, activated by the property target-env with a value of dev, which| provides a specific path to the Tomcat instance.

2.2 git下载
在jenkins中自动构建项目的时候我们的第一步是从gitlab仓库中拉取我们的代码所以必不可少需要进行git的安装 如果自动安装失败需要修改jenkins的镜像文件
#进入配置文件
vim /etc/docker/daemon.json
# 在文件在最后增添如下源地址
registry-mirrors: [https://docker.m.daocloud.io,https://dockerhub.icu,https://registry.aliyuncs.com,https://docker.nju.edu.cn]
# 保存后退出
# 重启加载dokcer配置
systemctl reload daemon.json
# 重启docker容器使之生效
systemctl restart docker如果还是安装失败可自行百度“centos7系统安装git的教程”安装过程较为简单这里不再赘述
3、maven任务构建
我这里在gitlab中创建了一个非常基础的maven项目进行测试所以构建了maven项目 如果你的界面中没有这个maven任务构建的选项则说明你没有安装对应的maven插件可在安装完对应maven插件后再继续进行。 构建任务的命名按自己的意向命名即可 构建完成任务后进入配置界面
3.1 重要配置描述
git配置 URL需要到安装的虚拟机中的gitlab项目中进行复制 第二步需要需要添加gitlab凭证就是你登录部署gitlab这台虚拟机的账户和密码 在配置完全局凭证之后就可以在任务中的凭证栏选择你刚才配置的凭证了 触发器默认选第一项即可 build栏目如下
build post的配置
在我们进行完成jar包的构建之后需要将构建好的jar包文件打包成docker镜像并上传到harbor仓库之中选择第二个选项的意思是在完成jar的打包之后才进行下一步然后输入需要执行的shell脚本自行自动化部署
# 进入jenkins打包完成的地址下面有构建完成的jar包你们打包完成后如果没有进行目录的修改前缀应该和我的相同
cd /var/lib/jenkins/workspace/test-bjw/
# 进行docker镜像的构建注意命名不可以用大写否则会报错还有就是这条命令最后有一个‘.’不要忽略它表示在该目录下执行
docker build -t jenkins_bjw-1.0-snapshot .
# 连接远程harbor仓库
docker login -u admin -p Harbor12345 192.168.1.5:80
# 对docker镜像进行tag标签处理
docker tag jenkins_bjw-1.0-snapshot 192.168.1.5:80/jenkins/jenkins-bjw:v0
# 上传到harbor仓库之中
docker push 192.168.1.5:80/jenkins/jenkins-bjw:v0构建不成功的可看下一节“可能遇到的问题”
4、 可能遇到的问题
1maven打包jar包失败
maven默认情况下下载依赖的仓库地址非常慢如果jenkins在进行jar包构建的时候依赖下载失败请重新检查是否更换了mirror地址具体操作在本文开始环节
2docker构建镜像的时候找不到Dockerfile文件
docker构建项目的时候需要安装Dockerfile的配置进行但是有时候我们的目录下并没有该Dockerfile文件所以需要进行Dockerfile文件的创建 1、从idea中打开对应项目并复制Dockerfile下的内容 2、创建Dockerfile文件
vim Dockerfile插入刚才复制的内容如果你的项目中没有可以按照我的文件进行修改
3docker中jenkins用户组不存在或者权限不足
我们知道jenkins在进行任务构建的时候需要进行dokcer命令的执行若权限不足会导致失败
# 在docker中添加jenkins用户组
sudo usermod -aG docker jenkins
# 若还是失败可以重启Jenkins和docker使该命令生效4虚拟机中配置insecure-registries
不配置该条目将无法访问harbor容器
# 进入配置文件
vim /etc/docker/daemon.json
# 增添对应配置对应上面的截图进行修改
insecure-registries: [harbor.domain.io]
# 重启docker服务使之生效
service docker restart
效果如下为harbor的虚拟机ip地址以及对应的服务端口号 5上传harbor容器的时候可能会因为命令输入错误而失败对应的操作详见我的另一篇博客“虚拟机CentOS7虚拟机安装harbor及简单使用”
5、 成功部署
jenkins控制台输出如下 harbor容器中docker镜像如下
