运行码头容器包含golang项目的问题

Question

当试图运行包含golang应用程序的我的坞映像时，我遇到了一些问题。这是一个错误：enter code herestandard_init_linux.go:211: exec用户进程导致"exec格式错误“。

这是我的环境：

码头文件：

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后，如下所示：RUN cd $SRC_DIR && env && goenv && export GO111MODULE=on && go get -u && go build -o application && cp application /app/

docker build .命令的输出：

Answer 1

standard_init_linux.go:211: exec user process caused "exec format error"错误是由于各种原因而发生的，而且不只是像许多论坛所说的那样，您尝试使用与主机不同的架构来启动映像。在我的示例中，发生此错误的原因是绑定程序被放置在停靠器容器中的错误目录中。

Answer 2

如果您查看输出错误，您可以清楚地看到错误消息：

/bin/sh: 1: goenv: not found

我猜你想在你的命令中输入go env？
