docker - 跑 docker 导出

Question

我使用 docker save <repository>:<tag> > image.rar 导出图像，然后使用 docker import image.rar 将其导入另一个系统。
我可以在运行 docker image ls 时看到图像，但是当我尝试运行它时，似乎在图像上找不到任何命令。
例如:

# docker run -ti -p 3000:3000 myimage:latest /bin/bash
docker: Error response from daemon: OCI runtime create failed: container_linux.go:345: starting container process caused "exec: \"/bin/bash\": stat /bin/bash: no such file or directory": unknown.

我注意到其他一些文章提到使用 docker inspect 来检查“Cmd”值，但无论出于何种原因，我都显示 null

我不太确定在导入过程中可能出了什么问题。我想我以前可能已经成功地做到了这一点，但也许没有。

Answer 1

尝试使用 docker load而不是 docker import你应该很好。

docker 保存 => docker 负载

docker 导出 => docker 进口

以上是正确的顺序
