Jenkins部署Golang
编译环境：
1.安装go语言
2.优化测试
部署环境：
1.部署
第一步：编译环境（Jenkins）
1.安装golang语言
#1.下载golang
[root@jenkins opt]# wget https://golang.google.cn/dl/go1.16.7.linux-amd64.tar.gz
#2.安装
[root@jenkins opt]# tar -xf go1.16.7.linux-amd64.tar.gz -C /usr/local/
#3.添加软连接
[root@jenkins /usr/local]# ln -s /usr/local/go /usr/local/golang
#4.添加环境变量
[root@jenkins opt]# vim /etc/profile.d/go.sh
export GO_HOME=/usr/local/go
export GO_ROOT=/usr/local/go
export GO_PATH=/opt/go
export GOPROXY=https://mirrors.aliyun.com/goproxy/
PATH=$PATH:$GO_HOME:$GO_ROOT:$GO_PATH:$GO_HOME/bin
export PATH
[root@jenkins opt]# source /etc/profile
[root@jenkins opt]# printenv |grep GO
GO_PATH=/opt/go
GOPROXY=https://mirrors.aliyun.com/goproxy/
GO_HOME=/usr/local/go
GO_ROOT=/usr/local/go
2.测试
# 1.创建目录
[root@jenkins opt]# mkdir /opt/go
[root@jenkins go]# go mod init jenkins-go #创建一个go.mod文件
total 4
-rw-r--r-- 1 root root 27 Aug 16 20:40 go.mod
#2下载go
[root@jenkins go]# go get -u github.com/gin-gonic/gin #下载
#3.编写main.go文件
[root@jenkins go]# vim main.go
package main
import "github.com/gin-gonic/gin"
func main() {
r := gin.Default()
r.GET("/ping", func(c *gin.Context) {
c.JSON(200, gin.H{
"message": "pong",
})
})
r.Run("0.0.0.0:8888") // listen and serve on 0.0.0.0:8080 #因8080端口被占用，修改默认访问端口8080，改为8888
}
#4.运行go
# 方式一：
[root@jenkins go]# go run main.go
[GIN-debug] [WARNING] Creating an Engine instance with the Logger and Recovery middleware already attached.
[GIN-debug] [WARNING] Running in "debug" mode. Switch to "release" mode in production.
- using env: export GIN_MODE=release
- using code: gin.SetMode(gin.ReleaseMode)
[GIN-debug] GET /ping --> main.main.func1 (3 handlers)
[GIN-debug] Listening and serving HTTP on 0.0.0.0:8888
#方式二
[root@jenkins /opt/go]# go build main.go
[root@jenkins /opt/go]# ll
total 14556
-rw-r--r-- 1 root root 631 Aug 16 20:43 go.mod
-rw-r--r-- 1 root root 8914 Aug 16 20:46 go.sum
-rwxr-xr-x 1 root root 14883140 Aug 16 20:53 main
-rw-r--r-- 1 root root 235 Aug 16 20:48 main.go
[root@jenkins /opt/go]# ./main
[GIN-debug] [WARNING] Creating an Engine instance with the Logger and Recovery middleware already attached.
[GIN-debug] [WARNING] Running in "debug" mode. Switch to "release" mode in production.
- using env: export GIN_MODE=release
- using code: gin.SetMode(gin.ReleaseMode)
[GIN-debug] GET /ping --> main.main.func1 (3 handlers)
[GIN-debug] Listening and serving HTTP on 0.0.0.0:8888
第二步：部署环境（web）
1.准备源代码到远程仓库
#1.将源代码文件传到远程仓库
#下载远程仓库到本地
[root@k8s-m-01 go]# git clone git@192.168.15.101:root/jenkins-go.git
#将源代码移动到本地仓库
[root@k8s-m-01 go]# mv gin/ jenkins-go/
[root@k8s-m-01 go]# cd jenkins-go/
[root@k8s-m-01 jenkins-go]# ll
total 4
drwxr-xr-x 3 root root 88 Aug 16 21:07 gin
-rw-r--r-- 1 root root 24 Aug 16 21:09 README.md
[root@k8s-m-01 jenkins-golang]# git add gin/
#提交源代码到远程仓库
[root@k8s-m-01 jenkins-golang]# git commit -m 'init' .
[master d0dfdb5] init

#推送完成并创建标签
2.Jenkins部署
#!/bin/bash
git checkout $GIT_TAG
export GOPROXY=https://mirrors.aliyun.com/goproxy/
/usr/local/go/bin/go mod init jenkins-go
/usr/local/go/bin/go get -u github.com/gin-gonic/gin
rm -rf target && mkdir target
cd target
/usr/local/go/bin/go build ../gin/main.go
选择标签进行构建
在Jenkins服务器上测试构建
#go 保存的路径
[root@jenkins /usr/local/go/pkg/linux_amd64]# pwd
/usr/local/go/pkg/linux_amd64
[root@jenkins /usr/local/go/pkg/linux_amd64]# ls

构建前部署
# 先main同步到挂载目录
[root@jenkins /var/lib/jenkins/workspace/jenkins-go/target]# scp -r main 192.168.15.111:/nfs/v4
yaml部署
#1.编写配置清单上传远程仓库

构建后部署
#!/bin/bash
chmod +x /nfs/v9/target/main
kubectl get pods -n golang | awk '{print $1}' | grep -v "NAME" | xargs -I {} kubectl delete pod -n golang {}
3.测试访问
#!/bin/bash
chmod +x /nfs/v9/target/main
