解决docker 编译golang项目报错 error obtaining VCS status: exec: “git“: executable file not found in $PATH

运行docker编译命令:

docker build -t svc:v1.1 .

然后报错：
#10 30.64 go: missing Git command. See https://golang.org/s/gogetcmd
#10 30.64 error obtaining VCS status: exec: “git”: executable file not found in $PATH
#10 30.64 Use -buildvcs=false to disable VCS stamping
详细如图：

Dockerfile文件如下

FROM golang:alpine AS builder

WORKDIR /go/src/svc

COPY . .

RUN go env -w GO111MODULE=on 
    && go env -w GOPROXY=https://goproxy.cn,direct 
    && go env -w CGO_ENABLED=0 
    && go env 
    && go mod tidy 
    && go build -o tagging-count-svc .

FROM alpine:latest

COPY --from=0 /go/src/svc/svc ./

RUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories && apk add --no-cache tzdata

然后尝试在环境变量变量里添加GOFLAGS=-buildvcs=false
查看go env

再次尝试编译仍然报相同的错误。

发现并不是要在主机修改GOFLAGS参数，而是要在docker容器内的go环境修改该参数。
解决方法：在Dockerfile文件中添加一行 && go env -w GOFLAGS=-buildvcs=false
修改Dockerfile文件如下

FROM golang:alpine AS builder

WORKDIR /go/src/svc

COPY . .

RUN go env -w GO111MODULE=on 
    && go env -w GOPROXY=https://goproxy.cn,direct 
    && go env -w CGO_ENABLED=0 
    && go env -w GOFLAGS=-buildvcs=false   # 添加在这里
    && go env 
    && go mod tidy 
    && go build -o tagging-count-svc .

FROM alpine:latest

COPY --from=0 /go/src/svc/svc ./

RUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories && apk add --no-cache tzdata

再次运行docker build命令即可编译成功。
