Docker compose 在构建过程中抛出错误：Service 'postgres' failed to build: exec: \"/bin/sh\": stat /bin/sh: no such file or directory": 未知

Question

我拉了一个新的 cookiecutter django 模板，我想使用 docker。当我执行docker-compose -f local.yml build 时，我收到此错误：

服务“postgres”构建失败：OCI 运行时创建失败：container_linux.go:346：启动容器进程导致“exec：\”/bin/sh\“：stat /bin/sh：没有这样的文件或目录” : 未知

研究了这个问题，我发现它可能是图像损坏。因此，我删除了所有容器、图像并使用以下命令修剪了系统：

docker rm -vf $(docker ps -a -q)
docker rmi -f $(docker images -a -q)
docker system prune

然后我也做了：

docker-compose -f local.yml down
docker-compose -f local.yml up

我重启了 docker，重启了我的电脑....

当我列出所有容器和图像时，它们都消失了。然后我再次构建它，这让我感到困惑，因为我得到：

所以还有一些东西存在吗？我认为某些内容没有被删除。然后一切都失败了：

ERROR: Service 'postgres' failed to build: OCI runtime create failed: container_linux.go:346: starting container process caused "exec: \"/bin/sh\": stat /bin/sh: no such file or directory": unknown

所以我猜我的 postgres 图像有问题......我只是不知道还能尝试什么。我有另一个项目可以与 docker 和 cookiecutter 完美配合。因此，我认为重新安装 docker 不会有帮助。

还有什么我可以尝试的想法吗？我不是 docker 专家，这几乎是我的故障排除知识的结束......非常感谢帮助，谢谢！

以下来自cookiecutter的自动创建：

如果您使用其他一些 linux 发行版，请尝试将此添加到您的 postgres Dockerfile 更改 apk

RUN apk add --no-cache dos2unix
RUN dos2unix YOUR_SCRIPT_NAME
RUN chmod +x YOUR_SCRIPT_NAME

并确保第一行是#!/bin/sh
