我一直在尝试制作一个Dockerfile,这将使我可以将我的go服务器构建为二进制文件,然后从头开始镜像或alpine运行它。该服务器在macOS 10.13.5上本地运行良好,当它不是来自Docker上的二进制文件时,我就使它可以工作。
我不断收到此错误:
standard_init_linux.go:190:exec用户进程导致“ exec格式错误”
我一直在四处搜寻,发现了一些有关系统架构的知识。我不确定如何检查这是否是错误和/或如何解决。
任何有关调试或可能修复的提示都将不胜感激。
我的Dockerfile:
FROM golang:1.10.3 as builder
WORKDIR /go/src/gitlab.com/main/server
COPY . .
RUN go get -d -v ./...
RUN CGO_ENABLED=0 GOOS=linux go build -a -o main .
FROM scratch
ADD main /
CMD ["/main"]
输出:

答案 0 :(得分:1)
正如@tgogos指出的那样,我是否需要使用第一步中构建的内容。
我的最终Dockerfile像这样以一些进一步的改进而结束:尽管重要的部分是倒数第二行:
FROM golang:1.10.3 AS build
WORKDIR /go/src/gitlab.com/main/server
COPY . .
RUN go get github.com/golang/dep/cmd/dep && \
dep ensure && \
rm -f schema/bindata.go && \
go generate ./schema
RUN CGO_ENABLED=0 GOOS=linux go build -a -o main .
FROM alpine
RUN apk add --no-cache ca-certificates
COPY --from=build /go/src/gitlab.com/main/server/main .
CMD ["/main"]
