HttpRequest0x02 Jenkins 插件使用说明
(1) SSH-steps-Plugin
项目描述: Jenkins流水线步骤，提供SSH工具，如命令执行或文件传输，以实现持续交付。 项目地址: https://github.com/jenkinsci/ssh-steps-plugin
代码语言：javascript复制Version: 2.0.0
Released: 2 years ago
Requires Jenkins 2.121.11) 在Jenkins中设置一个安全文本(Secret text)票据, 不建议使用明文票据;
代码语言：javascript复制# Secret text a2bc53c0-0b68-4fce-9f1f-d04815ae52c1 k8s-192.168.12.215 Secret text k8s-192.168.12.215Delactive Pipeline Script:
代码语言：javascript复制pipeline {
stages {
stage ('ssh-steps-plugin') {
steps {
script {
try {
def remote = [:]
remote.name = 'K8s-Master'
remote.user = 'root'
remote.host = '192.168.12.215'
//remote.password = 'password' // 明文不安全
remote.allowAnyHosts = true // 必须要运行所有主机
withCredentials([string(credentialsId: 'a2bc53c0-0b68-4fce-9f1f-d04815ae52c1', variable: 'sshpassword')]) {
remote.password = sshpassword
writeFile file: 'abc.sh', text: 'ls', encoding: 'utf-8'
sshPut remote: remote, from: 'abc.sh', into: '.' // 非常注意 不能为其它目录只能在当前路径之中
sshGet remote: remote, from: 'abc.sh', into: 'bac.sh', override: true
sshScript remote: remote, script: 'abc.sh'
sshRemove remote: remote, path: 'abc.sh'
sshCommand remote: remote, command: ' whoami && for i in {1..5}; do echo -n "Loop $i "; date ; sleep 1; done'
}
} catch(Exception err) {
echo err.toString()
error "[-Error] : ssh-steps-plugin测试失败n [-Msg] : ${err.getMessage()} "
}
}
}
}
}
}输出结果

# Host key checking is off. It may be vulnerable to man-in-the-middle attacks.

2) 官网示例中采用密钥进行验证操作 描述: 利用Jenkins凭据存储区读取私钥之后再进行ssh主机验证操作，但是需要注意高版本的Openssh的影响。
代码语言：javascript复制def remote = [:]
remote.name = "node-1"
remote.host = "10.000.000.153"
remote.allowAnyHosts = true
withCredentials([sshUserPrivateKey(credentialsId: 'sshUser', keyFileVariable: 'identity', passphraseVariable: '', usernameVariable: 'userName')]) {
remote.user = userName
remote.identityFile = identity
stage("SSH Steps Rocks!") {
writeFile file: 'abc.sh', text: 'ls'
sshCommand remote: remote, command: 'for i in {1..5}; do echo -n "Loop $i "; date ; sleep 1; done'
sshPut remote: remote, from: 'abc.sh', into: '.'
sshGet remote: remote, from: 'abc.sh', into: 'bac.sh', override: true
sshScript remote: remote, script: 'abc.sh'
sshRemove remote: remote, path: 'abc.sh'
}
}3) 远程主机文件上传与删除 执行脚本:
代码语言：javascript复制try {
def projectProduct = sh returnStdout: true, script: "find ${APP_FILE}" // returnStatus: true
def productName = sh returnStdout: true, script: "echo ${JOB_NAME}-${RELEASE_VERSION}${APP_SUFFIX}"
def remote = [:]
remote.name = "K8s-Master#${DEPLOY_HOST}"
remote.user = "weiyigeek" // "${DEPLOY_USER}"
remote.host = "192.168.12.107" //"${DEPLOY_HOST}"
remote.port = 20211
remote.allowAnyHosts = true // 必须要运行所有主机
withCredentials([string(credentialsId: "${DEPLOY_CREDENTIALSID}", variable: 'sshpassword')]) {
remote.password = sshpassword
}
if (productName != '' && projectProduct != ''){
println(projectProduct "-" productName)
writeFile file: 'projectProduct.sh', text: "${productName}"
} else {
error "[-Error] : projectProduct 不能为空!"
}
sshPut remote: remote, from: "/home/jenkins/agent/workspace/HelloWorld/target/hello-world.war" , into: "${APP_DIR}"
sshCommand remote: remote, command: "ls -alh ${APP_DIR}"
}输出结果:
代码语言：javascript复制target/hello-world.war - hello-world-v1.31.war
projectProduct.sh — Write file to workspace < 1s

SSH Steps: sshPut - Put a file/directory on remote node.6s

(2) Gitlab-Plugin
官方地址: 帮助文档: https://github.com/jenkinsci/gitlab-plugin#pipeline-jobs
Gitlab Triggers Setting 如果您想在声明式构建中配置插件支持的任何可选作业触发器请使用触发器块，完整的可配置触发选项列表如下:
代码语言：javascript复制// 触发器
triggers {
// gitlab 相关触发
gitlab(
triggerOnPush: false,
triggerOnMergeRequest: true, triggerOpenMergeRequestOnPush: "never",
triggerOnNoteRequest: true,
noteRegex: "Jenkins please retry a build",
skipWorkInProgressMergeRequest: true,
ciSkip: false,
setBuildDescription: true,
addNoteOnMergeRequest: true,
addCiMessage: true,
addVoteOnMergeRequest: true,
acceptMergeRequestOnSuccess: false,
branchFilterType: "NameBasedFilter",
includeBranchesSpec: "release/qat",
excludeBranchesSpec: "",
pendingBuildName: "Jenkins",
cancelPendingBuildsOnUpdate: false,
secretToken: "abcdefghijklmnopqrstuvwxyz0123456789ABCDEF")
}Tips : 注意:您将需要手动运行此作业一次，以便Jenkins读取和设置触发器配置。否则 webhook 将无法触发作业。
Gitlab PipeLine Status Sync 描述: Jenkins 创建的 Pipeline 同步到 Gitlab-CI 流水线之中;
代码语言：javascript复制pipeline {
agent any
options {
gitLabConnection('your-gitlab-connection-name')
gitlabBuilds(builds: ['build', 'test', 'deploy'])
}
stage {
stage("build") {
gitlabCommitStatus("build") {
// your build steps
}
}
stage("test") {
gitlabCommitStatus("test") {
// your test steps
}
}
}
post {
failure {
updateGitlabCommitStatus name: 'build', state: 'failed'
}
success {
updateGitlabCommitStatus name: 'build', state: 'success'
}
}
}(3) Kubernetes-plugin
描述: 通过该插件我们可以实现 Jenkins 管理 Kubernetes 集群以及实现自动化部署;
Jenkins 服务有关 Kubernetes 的插件介绍:
- 1.Kubernetes Credentials 认证插件: 设置连接过程中使用到的信息，包括 Kubernetes Master 的链接地址、证书、用户名和命名空间等
- 2.Kubernetes CLI 管理插件: 结合上面的认证插件使用，通过 kubectl 客户端来管理 Kubernetes 服务，但是这个插件并不会在 Jenkins 服务所在主机上安装 Kubectl 工具，所以你需要自行安装。
- 3.Kubernetes 插件: 用于将 Jenkins 服务和 Kubernetes 服务结合起来, 使用其插件的前提条件是设置好 Kubernetes 服务的链接配置，并在 Pipeline 中使用相应的指令。该插件提供的指令有
PodTemplate 、slaveTemplates、kubernetes等指令；而不是通过 Kubectl 客户端进行管理
Tips : 如果不想使用Kubernetes插件进行管理K8s集群, 我们可以设置一台服务器为 Kubernetes 服务的客户端，配置好 Kubectl 客户端；让 Jenkins 服务通过 SSH 方式连接到客户端执行管理命令。

// 确认使用主机/节点机
agent any /*{ node { label 'master'} }*/
// 声明使用的工具(便于不同环境构建)
tools {
maven 'maven_env'
jdk 'jdk_k1.8.0_211'
}
// 流水线步骤声明
stages {
stage ("代码拉取") {

env.deploy_option = input message: '选择操作', ok: 'deploy', parameters: [description: '选择部署环境',choice(name: 'deploy_option', choices: ['deploy', 'rollback', 'redeploy'])];
}
}
// (3) 切换版本
sh label: 'build', script: '[ -n "${git_version}" ] && git checkout ${git_version} || { echo -e "切换的tag的版本${git_version} 不存在或为空请检查输入的tag!" && exit 1; }'
}

}
}
stage ("项目部署") {
steps {
sh label: 'deploy', script: '/tmp/script/maven-jenkins-ci-script-pipeline-webhook.sh'
}
}
}
//消息通知: POST阶段当所有任务执行后触发
post {

(5) File Operations - Plugin
描述: 在 Jenkins Pipeline 中，我们经常需要对文件、目录或者tar、zip等压缩包进行操作，比如移动、复制、重命名等等, 而采用sh复制正对于一些安全票据的操作时，会报出以下警告对于强迫症的我是接受不了的并且确实有安全隐患。
代码语言：javascript复制# 提示1.
The following steps that have been detected may have insecure interpolation of sensitive variables (click here for an explanation):
sh: [keyfile, user]
# 提示2.
Warning: A secret was passed to "sh" using Groovy String interpolation, which is insecure.
Affected argument(s) used the following variable(s): [keyfile, user]
See https://****.io/redirect/groovy-string-interpolation for details.
cp **** ./id.private解决办法: 我们可以通过安装 File Operations Plugin 插件来解决上述问题。
插件地址: https://plugins.jenkins.io/file-operations
支持操作:
# Array / List of Nested Choice of Objects
fileCopyOperation
fileCreateOperation
fileDeleteOperation
fileDownloadOperation
fileJoinOperation
filePropertiesToJsonOperation
fileRenameOperation
fileTransformOperation
fileUnTarOperation
fileUnZipOperation
fileZipOperation
folderCopyOperation
folderCreateOperation
folderDeleteOperation
folderRenameOperation基础示例:
代码语言：javascript复制# 1.创建目录
script {
fileOperations([folderCreateOperation('directoryname')])
}
# 2.文件创建
script {
fileOperations([fileCreateOperation(fileContent: 'devops', fileName: 'test.json')])
}
# 3.文件复制
# flattenFiles: 如果选中，文件将直接复制到目标位置，而不保留源文件子目录结构。
fileOperations ([
folderCopyOperation(includes: "*", targetLocation: ".", flattenFiles: true)
])
# 4.目录复制
fileOperations ([
folderCopyOperation(sourceFolderPath: "/path/to/src", destinationFolderPath: "/path/to/dest"),
folderCopyOperation(sourceFolderPath: "/path/to/foo", destinationFolderPath: "/path/to/bar")
])
