k8s+docker部署Golang项目

Go环境搭建

• root帐户

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

建立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

# 添加如下内容：
export GOROOT=/usr/local/go
export PATH=$PATH:$GOROOT/bin
export GOPATH=/go
export GO111MODULE=auto
export GOPROXY=https://goproxy.cn,direct

# 使配置文件生效
[root@infra2-test-k8s /]# source /etc/profile

# 校验
[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

插件管理可选插件Go

配置Go环境

系统管理>全局工具配置>Go>Go安装

自动安装go1.14.4/usr/local/go

若是出现如下问题：docker

go: command not found

解决办法：apache

[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：vim

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
