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：文章来源：https://www.toymoban.com/news/detail-831761.html
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
