一、异常

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
