GO 编译时在此[golang:1.20-alpine]docker镜像内编译失败?

[admininfon]

shell: GOARCH=amd64 go build -o bin/hawk-grpc -ldflags "-s -w" .

• Error:

  package command-line-arguments
  imports hawk-rpc-go/config/viper
  imports hawk-rpc-go/config/qconf: build constraints exclude all Go files in /Users/kanghuixin/go/src/hawk-rpc-go/config/qconf

  获取Qconf配置加载到viper组件内.

• File: hawk-rpc-go/config/qconf/index.go 与 driver/go/src/infra/go_qconf/go_qconf.go内容一致, 拷贝过来.

请查找下问题, 为啥忽略呢?

找到问题:

1. 没有在该镜像编译安装QConf
2. 没有加载cgo编译参数, 文件go_qconf.go import "C" 部分有注释说明, 添加 -L qconf -L m 参数

下面有追加镜像编译打包汇总.

• Golang 编译步骤与问题汇总:
  1. centos:latest 镜像编译安装QConf
  2. 更新DNF与yum, LInk:https://haydenjames.io/fix-error-failed-to-download-metadata-for-repo-appstream-centos-8/

     dnf --disablerepo '*' --enablerepo=extras swap centos-linux-repos centos-stream-repos
     dnf distro-sync

  3. 建立软链接: ln -s /usr/local/qconf/lib/libqconf.so /usr/lib64/libqconf.so 未找到libqconf.so解决方案
  4. go代理链接失败: go env -w GOPROXY=https://goproxy.cn,direct 解决方案
  5. 编译报错[build constraints exclude all Go files]: go build -o main-cli -ldflags "-L qconf -L m -s -w" . 添加cgo编译参数解决
  6. 感觉镜像比较大, 可以使用FROM ... AS build, COPY --from=build $DIST_DIR/bin $RPC_DIR/bin 压缩进新镜像减小体积
