Answer 1

您的属性文件将复制到“构建器”阶段 - 在编译期间不需要它。相反，它应该被复制到最后阶段。

将 Docker 文件更新为：

FROM golang:1.13 as builder

WORKDIR /app

COPY invoke.go ./

COPY readproperties.go ./

#

# REMOVE:

#

# COPY config.properties ./

RUN CGO_ENABLED=0 GOOS=linux go build -v -o server

FROM fishtownanalytics/dbt:0.19.0

USER root

WORKDIR /dbt

COPY --from=builder /app/server ./

COPY script.sh ./

COPY jaffle-shop ./

#

# ADD:

#

COPY config.properties ./

#

# OR: copy it from the builder stage

#

#COPY --from=builder /app/config.properties ./

ENTRYPOINT ["./server"]
