macos - docker 在 mac 上运行 ubuntu 没有任何反应

Question

我在 mac 上运行:

docker is configured to use the default machine with IP 192.168.99.100
For help getting started, check out the docs at https://docs.docker.com

my-mac:mydir$ docker run ubuntu /bin/bash
my-mac:mydir$

难道我做错了什么？我不应该进入 ubuntu shell ？

Answer 1

通过运行 docker run ubuntu /bin/bash , docker 从镜像 ubuntu 创建一个随机命名的容器并运行 bash没有 stdin , stdout也不是 stderr然后 bash退出(刚启动后)。

尝试至少设置一个 tty 和交互模式(又名 foreground mode ):

 docker ps -a
 # if not exited, stop it first
 docker stop <container_id>
 # remove the container which cannot be used
 docker rm <container_id>

 # let's try again
 docker run -it --rm --name=test ubuntu bash

如 commented来自 physincubus :

• '-it' is the bit that makes it interactive,
• '--rm' removes the container when you exit (so if you want to be able to exit for detach and reattach later, do not do this), and
• '--name' allows you to name the container more explicitly in case you want to run multiple instances of the same container
