Bash completions not working in WSL in Docker Desktop 4.27.0+

[Conduitry]

Description

Upon upgrading to 4.27.0 (and persisting through 4.27.2), Bash command line completions have stopped working.

Reproduce

1. Open WSL prompt.
2. Type docker .
3. Press <tab>.

Expected behavior

Pressing <tab> should show Docker-specific subcommands and options, not a list of files and directories in the current directory.

Additional Info

I still have a /usr/share/bash-completion/completions/docker file, which is a symlink to /mnt/wsl/docker-desktop/cli-tools/usr/share/bash-completion/completions/docker, but the entire /mnt/wsl/docker-desktop/cli-tools/usr/share directory does not exist. /mnt/wsl/docker-desktop/cli-tools/usr only contains bin and local.

[segevfiner]

Same with zsh, you get compinit:503: no such file or directory: /usr/share/zsh/vendor-completions/_docker due to the now broken symlink

Having the same issue:

[matteo-zanoni]

4.28.0 released but still no fix...

[jonaskello]

Same issue, on start zsh:

compinit:503: no such file or directory: /usr/share/zsh/vendor-completions/_docker

There is a link to a missing file

❯ ls -lah /usr/share/zsh/vendor-completions/_docker
lrwxrwxrwx 1 root root 74 Feb 17 18:16 /usr/share/zsh/vendor-completions/_docker -> /mnt/wsl/docker-desktop/cli-tools/usr/share/zsh/vendor-completions/_docker
❯ ls -lah /mnt/wsl/docker-desktop/cli-tools/usr/share/zsh/vendor-completions/_docker
ls: cannot access '/mnt/wsl/docker-desktop/cli-tools/usr/share/zsh/vendor-completions/_docker': No such file or directory

So the actual missing file is /mnt/wsl/docker-desktop/cli-tools/usr/share/zsh/vendor-completions/_docker

So the actual missing file is /mnt/wsl/docker-desktop/cli-tools/usr/share/zsh/vendor-completions/_docker

Exactly same issue here: compinit:503: no such file or directory: /usr/share/zsh/vendor-completions/_docker

[hhromic]

Yes, same for me in Debian WSL2. I noticed that Docker autocompletion stopped working out of nowhere and after investigating I can confirm the issue is the same for me, the /mnt/wsl/docker-desktop/cli-tools/usr/share directory is missing:

$ ls -la /usr/share/bash-completion/completions/docker
lrwxrwxrwx 1 root root 78 Jan 18 22:26 /usr/share/bash-completion/completions/docker -> /mnt/wsl/docker-desktop/cli-tools/usr/share/bash-completion/completions/docker

$ stat -L /usr/share/bash-completion/completions/docker
stat: cannot statx '/usr/share/bash-completion/completions/docker': No such file or directory

$ ls -la /mnt/wsl/docker-desktop/cli-tools/usr/
total 8
drwxr-xr-x 4 root root 2048 Feb 19 10:23 .
drwxr-xr-x 3 root root 2048 Feb 19 10:23 ..
drwxr-xr-x 2 root root 2048 Feb 19 10:23 bin
drwxr-xr-x 4 root root 2048 Feb 19 10:23 local

[rickliujh]

temporally workaround found here https://gist.github.com/ro31337/b2c33ad0b90636e9e3bb76fb4fb76907

[zwik]

Still broken in 4.29.0.

[MtkN1]

Temporary workaround. Generate a completion file with docker completion SHELL.

bash:

docker completion bash > ~/.local/share/bash-completion/completions/docker.bash

[bsousaa]

FYI there is work internally at Docker happening in this area. Thanks for your patience.

[bsousaa]

Fix planned for Desktop 4.30 in a couple of weeks

[zwik]

Works in 4.30 for me in combination with zsh.

[jonaskello]

Can also confirm it works on my computer with 4.30 and zsh. Thanks for fixing!

[bsousaa]

Closing this issue as it's fixed with 4.30. Thanks again for your patience!
