WSL2 Ubuntu 20.04 无 output 用于 Docker 容器

Question

Issue

I'm on WSL2 Ubuntu 20.04, trying to run a Docker container in "interactive tty" mode, and I simply can't see the output of the container in the terminal.

Steps to reproduce

1. WSL2 terminal - Run a container and execute a command

   $ docker run --rm -it alpine:3.12 # in container $ ls # hit enter, can't see anything

2. WSL terminal - Scroll up and then down, suddenly the output appears

I was able to overcome it with ttyd , but I prefer using my terminal, any leads on this one?

Things that I've tried

1. Ubuntu 20.04 is my default distribution

   PS C:\WINDOWS\system32> wsl --list --verbose NAME STATE VERSION * Ubuntu-20.04 Running 2 docker-desktop-data Running 2 docker-desktop Running 2

2. Docker for Desktop > Settings > Resources > WSL Integration > Checked both Enable integration with my default WSL distro and Ubuntu-20.04 . I also unchecked, Applied & Restarted > Same results
3. Troubleshooting Windows Subsystem for Linux > OpenSSH-Server connection issues
4. PowerShell as Administrator > wsl --shutdown > Same results
5. I can see the output of a container that prints something

    $ docker run -it --rm unfor19/catfact:1.0 sh Cat fact: The first cartoon cat was Felix the Cat in 1919. In 1940, Tom and Jerry starred in the first theatrical cartoon “Puss Gets the Boot.” In 1981 Andrew Lloyd Weber created the musical Cats, based on TS Eliot's Old Possum's Book of Practical Cats

Answer 1

I guess it's related to the fact my $PATH variable was changed in my ~/.bashrc file.

I was able to fix it by following the instructions in

• Troubleshooting Windows Subsystem for Linux > Running Windows commands fails inside a distribution

Adding the following line to my ~/.bashrc followed by wsl --shutdown fixed it

# Support Windows commands
export PATH="${PATH}:/mnt/c/Windows/system32"
