Go环境搭建
root账户
下载Golang
[root@infra2-test-k8s /]# cd /usr/local/
[root@infra2-test-k8s local]# wget https://dl.google.com/go/go1.14.4.linux-amd64.tar.gz
[root@infra2-test-k8s local]# tar -xzvf go1.14.4.linux-amd64.tar.gz
创建Go目录
[root@infra2-test-k8s local]# cd /
[root@infra2-test-k8s /]# mkdir go
配置环境变量并设置代理
[root@infra2-test-k8s /]# vim /etc/profile
export GOROOT=/usr/local/go
export PATH=$PATH:$GOROOT/bin
export GOPATH=/go
export GO111MODULE=auto
export GOPROXY=https://goproxy.cn,direct
[root@infra2-test-k8s /]# source /etc/profile
[root@infra2-test-k8s /]# go version
go version go1.14.4 linux/amd64
[root@infra2-test-k8s /]# go env
Jenkins配置Golang环境
下载Go插件
在插件管理的可选插件中搜索Go然后点击直接安装,安装完毕之后需要重启jenkins。
file
配置Go环境
系统管理>全局工具配置>Go>Go安装
去掉自动安装的勾选,然后别名:go1.14.4,安装目录:/usr/local/go
file
如果出现以下问题:
go: command not found
解决办法:
[root@infra2-test-k8s bin]# ln -s /usr/local/go/bin/go /usr/bin/
还不行的话则尝试将环境变量配置到jenkins中:
GOROOT=/usr/local/go
PATH=/sbin:/usr/sbin:/bin:/usr/bin:/usr/local/sbin:/usr/local/jdk1.8.0_231/bin:/opt/apache-maven-3.6.3/bin:/usr/local/go/bin
GOPATH=/go
GO111MODULE=on
GOPROXY=https://goproxy.cn

Dockerfile
Dockerfile

ENTRYPOINT [“sh”, “/opt/docker/start.sh”, “test”]
start.sh:
#!/bin/bash
if [[ $1 == ‘prod’ ]]
then
sed -i “s/env=./env=DS_ONLINE/” ds.cnf
else
sed -i “s/env=./env=DS_DEV/” ds.cnf
fi
echo “启动应用”
./goapp > ./nohup.out
build.sh
#!/bin/sh
cd src/dataservice/
pwd
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -a dataservice.go
因为项目结构是:
dataservice
├── pkg
├── build.sh
└── src
├── dataservice
│ └── dataservice.go
│ └── start.sh
│ └── ds.cnf
└── go.mod
并且使用了go modle,如果直接build src/dataservice/dataservice.go文件的话会报错,提示找不到依赖的包,jenkins pipeline又不支持cd命令,进不了src/dataservice/目录,只能想了个折中的办法,使用build.sh脚本执行打包命令。
