尝试运行包含golang应用程序的docker映像时遇到一些问题。 这是错误：请enter code here standard_init_linux.go：211：exec用户进程导致“ exec格式错误”

这是我的环境：

dockerfile：

FROM golang:1.12.0

WORKDIR /app

ENV SRC_DIR=/go/src/vk_acceptor/

ADD . $SRC_DIR

RUN cd $SRC_DIR; env; goenv; export GO111MODULE=on; go get -u; go build -o application; cp application /app/

RUN chmod +x application

ENTRYPOINT ["./application"]

格式化RUN command它看起来像这样： RUN cd $SRC_DIR && env && goenv && export GO111MODULE=on && go get -u && go build -o application && cp application /app/

docker build .输出docker build . 命令：

Answer 1

如果查看输出错误，则可以清楚地看到错误消息：

/bin/sh: 1: goenv: not found

我想您想在命令中键入go env ？

Answer 2

standard_init_linux.go:211: exec user process caused "exec format error"各种原因standard_init_linux.go:211: exec user process caused "exec format error"错误发生，这不仅是由于许多论坛所说的，不仅是当您尝试使用不同于主机的体系结构启动映像时。 在我的情况下，由于将捆绑的程序放置在Docker容器中的错误目录中而发生此错误。
