一、Jenkins配置

1.1、pipeline插件安装

二、拉取git代码

pipeline {
    agent any
	stages {
		stage('Checkout') {
			steps {
				echo "1.克隆git仓库代码"
				git branch: 'dev', credentialsId: 'c253ee4c-f900-422b-b3f2-b83090ae6a9b', url: 'https://gitee.com/luckywxn/WeaveErpSoa.git'
				script {
					build_tag = sh(returnStdout: true, script: 'git rev-parse --short HEAD').trim()
				  }
				echo "${build_tag}"
			}
		}
	}
}

三、Maven打包spring项目

pipeline {
    agent any
	stages {
		stage('Checkout') {
			steps {
				echo "1.克隆git仓库代码"
				git branch: 'dev', credentialsId: 'c253ee4c-f900-422b-b3f2-b83090ae6a9b', url: 'https://gitee.com/luckywxn/WeaveErpSoa.git'
				script {
					build_tag = sh(returnStdout: true, script: 'git rev-parse --short HEAD').trim()
				  }
				echo "${build_tag}"
			}
		}
		stage('Maven Build') {
            steps {
				echo "2.Maven 打包项目"
                sh "mvn --version"
				sh 'pwd'
				sh 'mvn clean package -DskipTests'
				echo '构建完成'
            }
        }
	}
}

三、docker构建镜像

pipeline {
    agent any
	stages {
		stage('Checkout') {
			steps {
				echo "1.克隆git仓库代码"
				git branch: 'dev', credentialsId: 'c253ee4c-f900-422b-b3f2-b83090ae6a9b', url: 'https://gitee.com/luckywxn/WeaveErpSoa.git'
				script {
					build_tag = sh(returnStdout: true, script: 'git rev-parse --short HEAD').trim()
				  }
				echo "${build_tag}"
			}
		}
		stage('Maven Build') {
            steps {
				echo "2.Maven 打包项目"
                sh "mvn --version"
				sh 'pwd'
				sh 'mvn clean package -DskipTests'
				echo '构建完成'
            }
        }
		stage('Docker Build') {
            steps {
				echo "3.Docker 构造镜像"
				sh "docker -v"
				sh 'pwd'
				sh """cd /var/jenkins_home/workspace/test/weaveserviceservice/src/main/docker/ 
				ls
				docker -H tcp://127.0.0.1:80 build -t springbootapp:${build_tag} ."""
            }
        }
	}
}

遇到的问题：
在使用docker build命名的时候，报如下错误

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

解决方案：
在jenkins 启动的docker-compose文件中增加如下配置

/var/run/docker.sock:/var/run/docker.sock

四、docker推送镜像

def servicename = "weaveservice"
node {
	stage('Checkout') {
		echo "1.克隆git仓库代码"
		git branch: 'dev', credentialsId: 'c253ee4c-f900-422b-b3f2-b83090ae6a9b', url: 'https://gitee.com/luckywxn/WeaveErpSoa.git'
		script {
			build_tag = sh(returnStdout: true, script: 'git rev-parse --short HEAD').trim()
		  }
		echo "${build_tag}"
	}
	stage('Maven Build') {
		echo "2.Maven 打包项目"
		sh "mvn --version"
		sh 'pwd'
		sh 'mvn clean package -DskipTests'
		echo '构建完成'
	}
	stage('Docker Build') {
		echo "3.Docker 构造镜像"
		sh "docker -v"
		sh 'pwd'
		sh """cd /var/jenkins_home/workspace/test/weaveserviceservice/src/main/docker/ 
		ls
		docker build -t 127.0.0.1:80/dev/${servicename}:${build_tag} ."""
	}
	stage('Docker Push') {
		echo "4.Docker 推送镜像"
		withCredentials([usernamePassword(credentialsId: "0fbd81ff-a45b-4e8b-9355-a2a5a36438c0", passwordVariable: "password", usernameVariable: "username")]) {
			sh "docker login 127.0.0.1:80 -u ${username} -p ${password}"
			sh "docker push 127.0.0.1:80/dev/${servicename}:${build_tag}"
		}
	}
}

遇到的问题：
在使用docker build命令的时候，报如下错误

Cannot perform an interactive login from a non TTY device

解决方案：
参考博文Docker、Jenkins、Harbor 构建镜像部署 SpringBoot 项目，先不在jenkins中执行，先在宿主机上执行是否可以成功，然后在jenkins中编写对应脚本就可以了。

五、kubelctl执行

def harborurl = "127.0.0.1:80"
def servicename = "weaveservice"
node {
	stage('Checkout') {
		echo "1.克隆git仓库代码"
		git branch: 'dev', credentialsId: 'c253ee4c-f900-422b-b3f2-b83090ae6a9b', url: 'https://gitee.com/luckywxn/WeaveErpSoa.git'
		script {
			build_tag = sh(returnStdout: true, script: 'git rev-parse --short HEAD').trim()
		  }
		echo "${build_tag}"
	}
	stage('Maven Build') {
		echo "2.Maven 打包项目"
		sh "mvn --version"
		sh 'pwd'
		sh 'mvn clean package -DskipTests'
		echo '构建完成'
	}
	stage('Docker Build') {
		echo "3.Docker 构造镜像"
		sh "docker -v"
		sh 'pwd'
		sh """cd /var/jenkins_home/workspace/test/weaveserviceservice/src/main/docker/ 
		ls
		docker build -t ${harborurl}/dev/${servicename}:${build_tag} ."""
	}
	stage('Docker Push') {
		echo "4.Docker 推送镜像"
		withCredentials([usernamePassword(credentialsId: "0fbd81ff-a45b-4e8b-9355-a2a5a36438c0", passwordVariable: "password", usernameVariable: "username")]) {
			sh "docker login ${harborurl} -u ${username} -p ${password}"
			sh "docker push ${harborurl}/dev/${servicename}:${build_tag}"
		}
	}
	stage('Deploy') {
		echo "5. Deploy Kubernetes"
		sh "kubectl version"
		sh """cd /var/jenkins_home/workspace/test/weaveserviceservice/ 
		ls
		sed -i 's/<PROJECT_NAMESPACE>/app/' k8s.yaml
		sed -i 's/<DOCKER_REGISTRY>/${harborurl}/' k8s.yaml
		sed -i 's/<PROJECT_NAME>/${servicename}/' k8s.yaml
		sed -i 's/<BUILD_TAG>/${build_tag}/' k8s.yaml
		kubectl delete -f .
		kubectl apply -f k8s.yaml --record
		"""
	}
}

遇到的问题一：

在使用kubectl version命令的时候，报如下错误

Error from server (Forbidden): <html><head><meta http-equiv='refresh' content='1;url=/login?from=%2Fswagger-2.0.0.pb-v1%3Ftimeout%3D32s'/><script>window.location.replace('/login?from=%2Fswagger-2.0.0.pb-v1%3Ftimeout%3D32s');</script></head><body style='background-color:white; color:white;'>


Authentication required
<!--
-->

</body></html>

解决方案：
参考博文从 jenkins 容器运行 kubectl 命令，jenkins配置的环境变量中设置kubectl 的认证信息

遇到的问题二：

在使用kubectl apply -f k8s.yaml --record命令的拉取镜像的时候，报如下错误

container "weaveservice" in pod "weaveservice-dad798uvdkkd"is waiting pulled

解决方案：
参考博文k8s 1.23 拉取 harbor镜像失败，配置好后还是报错，后面突然发现，pod是在node节点拉取的镜像，然后在node节点的宿主机执行docker login 命令，发现又有如下报错：

Error response from daemon: Get "https://192.168.1.7:80/v2/": http: server gave HTTP response to HTTPS client

然后参考博文 Docker login 登录私服，报错； http: server gave HTTP response to HTTPS client操作后，docker login 命令执行成功，镜像拉取下来之后，pod也就自动启动了。大功告成！！！文章来源地址https://www.toymoban.com/news/detail-831761.html
