/bin/bash: Command not found in alpine docker
提问by salient
I'm trying to run this Makefilein an alpinedocker.
我正在尝试Makefile在alpinedocker 中运行它。
SHELL := /bin/bash
build:
GOOS=linux go build -o bin/server main.go
I have ascertained that both bash, make, gois there by interactively going into the container and checking all commands.
我已经确定，这两个bash，make，go在那里通过交互进入容器中，并检查所有的命令。
But this command mysteriously fails:
但是这个命令神秘地失败了：
+ make build
make: /bin/bash: Command not found
GOOS=linux go build -o bin/server main.go
make: /bin/bash: Command not found
make: *** [Makefile:17: build] Error 127
script returned exit code 2
I have a real hard time debugging this as it's in a docker and it's jenkinsthat is executing everything.
我真的很难调试它，因为它在 docker 中并且jenkins正在执行所有内容。

There is no /bin/bashin alpine:
/bin/bash高山没有：
$ docker run -i -t alpine
/ # ls /bin/bash
ls: /bin/bash: No such file or directory
Note that there is no makeor goneither. So, either you checked their existence in your host instead of in alpine, or you are not using vanilla alpine.
请注意，没有make或go都没有。因此，要么您检查了它们在您的主机中而不是在 alpine 中的存在，要么您没有使用 vanilla alpine。

use the package manager, named apk, this way:
使用名为 apk 的包管理器，如下所示：
% docker run --rm -it alpine /bin/sh
/ #
/ # apk add --no-cache bash
