standard_init_linux.go：178：exec用户进程导致“ exec格式错误” kubernetes

Question

我知道很多人都遇到过这个问题，但没有一个答案解决了我的问题。

工作流

• 我在一个Kubernetes集群(GoogleCloud)中运行我的所有dockers。
• 当我在GitHub上的主分支中提交时，我已经设置了编译触发器以自动构建我的dockerfile。
• 然后，我用以下方法更新我的Kubernetes部署： kubectl set image deployment/MYPROJECT MYPROJECT=eu.gcr.io/foo/MYPROJECT:$TRAVIS_COMMIT

哪儿错了？

我的pod停留在 crashloop back-off，日志：standard_init_linux.go:178: exec user process caused "exec format error"

一点背景

我的工作流程一直工作到2018年6月，我不知道出了什么问题，所以我根据网上的搜索结果，修改了我的dockerfile，更新了我的依赖项，更改了dockerfile的基本图像版本等等，但还是毫无办法。

Dockerfile

FROM golang:1.10-alpine3.7 AS builder
ADD . /go/src/github.com/foo/MYPROJECT
WORKDIR /go/src/github.com/foo/MYPROJECT/api
RUN CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -ldflags "-s -w" -a -installsuffix cgo -o /go/bin/api

FROM alpine:3.7
RUN apk --no-cache add ca-certificates
COPY --from=builder /go/bin/api /go/bin/api
COPY --from=builder /go/src/github.com/foo/MYPROJECT/api/sql /go/migrations/sql
COPY --from=builder /go/src/github.com/foo/MYPROJECT/api/.docs/swagger.yml /static/swagger.yml
RUN chmod +x /go/bin/api
ENTRYPOINT ["/go/bin/api"]

[EDIT: 12 June]

当问题出现时，我注意到docker的图像大小从6.3Mo增加到2.3Mo，我怀疑后面还会有新发现，我会继续研究。

Answer 1

Ok I found the issue. I post it here, in case someone is stupid like me. I made a change in my github repository, transforming 1 project/microservices into 1 monorepo for every microservices. During the refactor, I had no package main in my api microservice, and the go build DID NOT fail, but wrote a file of 90 Ko in the output destination.

SOLUTION

Ensure to have a main package

I feel really stupid but hey, it happens to everyone.

Thank you to commentators, you were right
