如何在 docker 容器中运行 /bin/bash？

Question

How to run /bin/bash in a docker container that was started with the -d option , for example:

sudo docker run -P --name test-cnt3 -d base-tst:0.1? 

I really need a console in the container and I already despaired of running it

Answer 1

使用docker exec在已经运行的容器中运行命令，使用-it创建一个新的交互式伪 TTY：

docker exec -it test-cnt3 /bin/bash

Answer 2

If you use docker-composer or Dockerfile look at Entrypoint & CMD

And to connect use sudo docker attach awesome-container

Answer 3

In my case, docker exec -it test /bin/bash gave me

Error response from daemon: Container f63bba8... is not running

When I tried

docker start test

the container started, but trying exec again threw the same error as before.

In the end, I had to enter

docker run -it test /bin/bash

This starts the bash right before the container stops.

Answer 4

docker exec -it container-name /bin/bash
