Go应用Docker容器中编译快速接入-应用实时监控服务(ARMS)-阿里云帮助中心

本文介绍如何在Go应用Docker容器中编译快速接入。

实施步骤

一、下载编译工具

在编译Go应用的Dockerfile文件中，在go build 之前加上下载instgo 和修改执行权限：

RUN wget "http://arms-apm-cn-hangzhou.oss-cn-hangzhou.aliyuncs.com/instgo/instgo-linux-amd64" -O instgo
RUN chmod +x instgo

在go build 时添加instgo：

RUN ./instgo go build {arg1} {arg2} {arg3}

WORKDIR /usr/src/app/

ENTRYPOINT [ "./checkoutservice" ]

二、添加环境变量运行

1、若使用阿里云容器环境，请参考容器服务 ACK 和容器计算服务 ACS 通过 ack-onepilot 组件安装 Go 探针中步骤一、步骤四完成接入。

2、若环境为非容器运行，请按如下示例配置环境变量：

export ARMS_ENABLE=true
export ARMS_APP_NAME=xxx   # 应用名称。
export ARMS_REGION_ID=xxx   # 对应的阿里云账号的RegionID。
export ARMS_LICENSE_KEY=xxx   # LicenseKey。

# run go
./main {arg1} {arg2} {arg3}

说明

LicenseKey获取方式：在DescribeTraceLicenseKey - 列出LicenseKey页面单击调试，选择需要上报的阿里云区域后单击发起调用即可获取LicenseKey。
