CI pipeline
CD pipeline
项目规范与总体设计
公司里面要使用流水线要做持续集成CI/CD的项目越来越多,这对流水线的设计和开发有不同的要求。我们经常听到用户的反馈:
各种不同语言的技术栈, 如何使流水线适配呢? 从不同技术栈维护一套流水线模版,到我们使用共享库进行统一的管理和维护。
对于不同的项目,大家管理代码的方式也不同。可能还有一部分用户在使用Svn等不同的版本控制系统。
不同的项目,开发模式也不太一样, 编译构建工具不同,发布的方式也有不同的地方…
等等,不止上面的问题。所以在做流水线的使用应该提前把项目团队的规范定义好, 这样后期项目改造后可以直接集成CI/CD流水线。更加便捷。
1.团队信息
信息项 | 描述 |
---|---|
业务简称/编号 | devops4 |
开发模式 | 特性分支开发,版本分支发布,主干分支作为最新代码 |
项目类型与构建方式 | 前端: vue项目, npm打包, 制品目录 dist 后端:springboot项目, maven打包, 制品目录 target |
发布主机环境(vm) | LB: 192.168.1.200 Server: 192.168.1.121~192.168.1.122 |
2.CI/CD规范
通过上面的信息,我们采用如下规范:
工具链 | |
---|---|
GitLab 代码库 | 仓库组: devops4 项目仓库后端 devops4-ops-service 前端 devops4-ops-ui |
Jenkins作业 | 文件夹: devops4 |
作业命名: 后端 devops4-ops-service 前端 devops4-ops-ui | |
CI构建规范 | 前端项目采用npm打包后统一放到dist目录下, 静态文件以tgz打包。 |
后端项目采用maven打包后统一放到target目录下,以jar包。 | |
Sonar代码报告 | 前端项目:devops4-ops-ui 后端项目:devops4-ops-service |
项目团队可以使用devops4命名的自定义质量规则和质量阈。 | |
Nexus制品库目录 |
devops4-ops-service/version/devops4-ops-service-version.jar |
devops4-ops-ui/version/devops4-ops-ui-version.tar.gz | |
devops4 | 版本: 分割release分支获取版本号 |
发布规范 | 用户输入版本,下载制品库,使用脚本启动服务。 |
版本分支命名:RELEASE-1.1.1
特性分支开发,版本分支发布。
使用virtualbox创建2台虚拟机, 或者采用terraform操作云平台创建2台虚机。
本次,自己使用2台本地vmwareworkstation虚机测试。
制品版本命名:版本号-CommitID
Jenkins pipeline * 2
CI pipeline
CD pipeline
环境存在两个版本,蓝版本和绿版本同时存在,部署新版本然后进行测试,将流量切到新版本,最终实际运行的只有一个版本(蓝/绿)。好处是无需停机,并且发布风险较小。
nginx upstream模块实现:
upstream webservers {
server 192.168.1.253:8099 weight=100;
server 192.168.1.252:8099 down;
}
server {
listen 8017;
location / {
proxy_pass http://webservers;
}
}
nginx -s reload
将发行版发布到一部分用户或服务器的一种模式。这个想法是首先将更改部署到一小部分服务器,进行测试,然后将更改推广到其余服务器。一旦通过所有运行状况检查,当没有问题时,所有的客户将被路由到该应用程序的新版本,而旧版本将被删除。
nginx 权重模拟:
upstream webservers {
server 192.168.1.223:8099 weight=100;
server 192.168.1.222:8099 weight=100;
server 192.168.1.221:8099 weight=100;
}
server {
listen 8017;
location / {
proxy_pass http://webservers;
}
}
nginx -s reload
1、前端项目
复制静态文件到nginx站点目录,nginx -s reload
## 进入Web服务器的站点目录下
## 下载包
[root@master html]# curl -u admin:admin123 http://192.168.1.200:8081/repository/anyops/com/anyops/anyops-devops-ui/1.1.1/anyops-devops-ui-1.1.1.tar.gz -o anyops-devops-ui-1.1.1.tar.gz
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 196k 100 196k 0 0 24.0M 0 --:--:-- --:--:-- --:--:-- 24.0M
## 解压包
[root@master html]# tar zxf anyops-devops-ui-1.1.1.tar.gz
[root@master html]# ls
anyops-devops-ui-1.1.1.tar.gz index.html static
## 触发nginx重载
[root@master html]# nginx -s reload
2、后端项目
devops6-maven-service
到devops6-maven-service_CI
保存后,点击参数化构建,会发现branchName
的页面参数为空,我们先直接运行一次流水线看看效果:
运行一次流水线后,再次运行时,就会看到branchName
正常了。
接下来我们就用devops6-maven-service_CI
来测试。
可以看到,流水线运行成功。
可以看到nexus仓库里制品被上传成功了。
appName = "${JOB_NAME}".split('_')[0] //devops6-maven-service_CI
repoName = appName.split('-')[0] //devops6
appVersion = "${env.branchName}".split("-")[-1] // RELEASE-1.1.1 1.1.1
targetDir="${appName}/${appVersion}"
再次运行测试效果:
符合预期。
devops6-maven-service_CD
作业,然后添加一些页面参数点击参数化构建:
[root@Devops6 ~]#cd /opt/jenkinsagent/workspace/
[root@Devops6 workspace]#ls
day2-pipeline-demo devops6-gradle-service devops6-maven-service devops6-maven-service_CI@tmp devops6-maven-test devops6-npm-service test-maven
day2-pipeline-demo@tmp devops6-gradle-service@tmp devops6-maven-service_CI devops6-maven-service@tmp devops6-maven-test@tmp devops6-npm-service@tmp test-maven@tmp
[root@Devops6 workspace]#cd devops6-maven-service_CI
[root@Devops6 devops6-maven-service_CI]#ls
mvnw mvnw.cmd pom.xml sonar-project.properties src target
[root@Devops6 devops6-maven-service_CI]#git rev-parse HEAD #通过这个命令之可以获取仓库comitID的。
b5cfb8eeee597edd752cb11f5daa9ac843fb9f97
[root@Devops6 devops6-maven-service_CI]#
然后利用片段生成器生成代码:
sh returnStdout: true, script: 'git rev-parse HEAD'
然后集成到piepeline代码里。
这里直接写代码:
appVersion = "${appVersion}-${env.commitID}"
//获取commitID
env.commitID = gitlab.GetCommitID()
println("commitID: ${env.commitID}")
package org.devops
//获取CommitID
def GetCommitID(){
ID = sh returnStdout: true, script:"git rev-parse HEAD"
ID = ID -"\n"
return ID[0..7] //取前8位id
}
devops6-maven-service
里以main分支创建RELEASE-9.9.9
分支devops6-maven-service_CI
流水线测试成功。
下载制品
cd部分就不用再下载代码获取commitID了。
我们来使用gitlab api获取分支commit。
https://docs.gitlab.com/
curl --header "PRIVATE-TOKEN: " "https://gitlab.example.com/api/v4/projects/5/repository/branches/main"
先拿取下一些参数:
这里拿到Project ID
:
然后在gitlab上创建一个token:
TLDgj3sz-cioyk6AfxZi
调试:
http://172.29.9.101:8076/api/v4/projects/7/repository/branches/RELEASE-9.9.9
添加get请求,添加PRIVARE-TOKEN
,点击Send。
此时,我们就通过gitalb api拿到了分支commitID了,和之前手动执行git命令获取的commitID信息一致。
curl --location 'http://172.29.9.101:8076/api/v4/projects/7/repository/branches/RELEASE-9.9.9' \
--header 'PRIVATE-TOKEN: TLDgj3sz-cioyk6AfxZi'
创建Gitlab.groovy文件
package org.devops
//发起HTTP请求
def HttpReq(method, apiUrl){
response = sh returnStdout: true,
script: """
curl --location --request ${method} \
http:172.29.9.101:8076/api/v4/${apiUrl} \
--header "PRIVATE-TOKEN: TLDgj3sz-cioyk6AfxZi"
"""
response = readJSON text: response - "\n" //json数据的读取方式
return response
}
但是,这里的gitlab token是明文的,因此需要在jenkins里配置个凭据。
然后利用片段生成器来利用次token,生成代码:
withCredentials([string(credentialsId: '5782c77d-ce9d-44e5-b9ba-1ba2097fc31d', variable: 'gitlabtoken')]) {
// some block
}
package org.devops
//发起HTTP请求
def HttpReq(method, apiUrl){
withCredentials([string(credentialsId: '5782c77d-ce9d-44e5-b9ba-1ba2097fc31d', variable: 'gitlabtoken')]) {
response = sh returnStdout: true,
script: """
curl --location --request ${method} \
http:172.29.9.101:8076/api/v4/${apiUrl} \
--header "PRIVATE-TOKEN: ${gitlabtoken}"
"""
}
response = readJSON text: response - "\n" //json数据的读取方式
return response
}
但是,存在一个问题,apiUrl里我们还需要知道ProjectID才行,这里继续查找gitlab api。
http://172.29.9.101:8076/api/v4/projects?search=devops6-maven-service
curl --location 'http://172.29.9.101:8076/api/v4/projects?search=devops6-maven-service' \
--header 'PRIVATE-TOKEN: TLDgj3sz-cioyk6AfxZi'
package org.devops
//发起HTTP请求
def HttpReq(method, apiUrl){
withCredentials([string(credentialsId: '5782c77d-ce9d-44e5-b9ba-1ba2097fc31d', variable: 'gitlabtoken')]) {
response = sh returnStdout: true,
script: """
curl --location --request ${method} \
http:172.29.9.101:8076/api/v4/${apiUrl} \
--header "PRIVATE-TOKEN: ${gitlabtoken}"
"""
}
response = readJSON text: response - "\n" //json数据的读取方式
return response
}
//获取ProjectID
def GetProjectIDByName(projectName, groupName){
apiUrl = "projects?search=${projectName}"
response = HttpReq("GET", apiUrl)
if (response != []){
for (p in response) {
if (p["namespace"]["name"] == groupName){
return response[0]["id"]
}
}
}
}
//获取分支CommitID
def GetBranchCommitID(projectID, branchName){
apiUrl = "projects/${projectID}/repository/branches/${branchName}"
response = HttpReq("GET", apiUrl)
return response.commit.short_id
}
cd.jenkinsfile

流水线使用共享库运行流水线:

下载制品成功。
我们再运行一次流水线:
会看到多了一个包,
最后我们发布完,会把它清掉的:

然后打包,运行,观察效果:
最后,将devops6-maven-service
的RELEASE-9.9.9/
代码合并到main分支。
打上tag
推荐第一种。
第二种方法会存在很多逻辑问题的。
1、直接发布版本方式来回滚
先运行CI流水线
CI pipeline运行成功:
再运行CD:
观察效果:
可以看到发布老版本程序成功。
2、使用回滚代码
注意:如果要回滚时,就需要跳过发布阶段,否则会有问题的,因此这里我给发布
阶段加了一个判断选项。
发布1.1.1
发布9.9.9
回滚到1.1.1:
符合预期。
return ["dev", "uat", "stag", "prod"]
if (envName.equals("dev")){
return ["172.29.9.110,172.29.9.111"]
} else if (envName.equals("uat")){
return ["172.29.9.120,172.29.9.121"]
}
⚠️ 注意:记得删除前面定义好的envName和deployHosts选项参数。
符合预期。
这个就不做演示了,和上面这个实践有冲突。
return ["ansible", "saltstack"]
单选类型
选择关联的参数,多个参数用逗号分割

2023.7.2-云主机模式持续部署-ci-cd-code
gitlab-ce:15.0.3-ce.0
jenkins:2.346.3-2-lts-jdk11
sonarqube:9.9.0-community
nexus3:3.53.0
这2条流水线都是测试ok的。(以后就一直用这2条流水线来测试devops了)
gitlab仓库devops6-maven-service
:RELEASE-9.9.9和main分支都是一样的代码。
