go build 时出现 undefined: kafka.Message
二、解决方法1、打开动态编译
ENV CGO_ENABLED=1
2、若是跨平台编译，目标平台是linux
需要添加：-tags musl
3、实例
FROM golang:1.13-alpine AS builder
ENV GOOS linux
ENV GOARCH amd64
# missed this very obvious change
ENV CGO_ENABLED 1
RUN apk update && apk upgrade &&
apk add --no-cache git
# needed for gcc
RUN apk add --no-cache git build-base
WORKDIR /build
COPY . ./
# confluent-kafka-go recommends musl tags for alpine linux builds
RUN go build -tags musl
