Docker 容器挂在 exec 命令上

Trying to execute shell commands in the docker container from localhost and inside the container,

  docker exec -i <container-id> sh -c "ls -l"

also tried docker exec -ti <container-id> sh -c "ls -l"

it lists the output and keeps on hanging in the terminal.

Executed the above command by login in to the container It lists the output and when i type exit command, it starts hanging

Server Free RAM: 3GB

docker logs --details <container-id> 

returns empty output

Answer 1

You need to allocate a pseudo-TTY with the -t option along with interactive or -i option. Try this:

$ docker exec -ti <container-id> sh -c "ls -l"

Answer 2

Had the same issue. I was passing a step-by-step docker tutorial. Was using Visual Studio 2022. In step-by-step tutorial worked fine.

When I tried myself docker exec command hanged.

The reason of the issue was that I used built in Visual Studio package manager console. But for running docker commands one should specifically start powershell console from the context menu of the solution.

Kind of similar happened for me too. Was using Phpstorm terminal and it hanged. Restarted server - nothing. Only complete reboot of phpstorm helped...
