Failed to connect. Is docker Installed?

[k3nd3r9]

Type: Bug

Visual Code fails to realize docker is installed.

I follow the post install instructions: https://docs.docker.com/engine/install/linux-postinstall/

I can "docker run hello-world" without sudo from terminal.

If I open code with sudo, it is able to run the extension fine.

If I open code normally, it is unable to find the extension, but I can open the terminal and run "docker info" and it reports normally. docker can see images from terminal.

I have added my user to the "docker group"

Seems like a permissions issue.

Ubuntu version 24.04.1 LTS

This could be a case where a full system restart is required for permissions to fully propagate. Can you try that if you haven't already?

[k3nd3r9]

Yes, I tried this already.

When you open VSCode normally (non-sudo), do you launch it from the terminal or somewhere else?

[k3nd3r9]

I launch it from the ubuntu apps normally. However this results in docker not being found. I got around this by launching in terminal with root access to find it could then see docker.

[bwateratmsft]

This might be a snap issue. Can you try the workarounds in here and see if that works?

[nanachan3835]

You can remove CODE config in ~/.config and then relogin VSCODe (non-sudo), after that you can see docker extension icon appear in taskbar. Remember sync this setting to your account. This work for me, you can try it. Hope you can fix this problem soon.

[niloykashyap]

Encountered the exact same issue. Followed all the steps mentioned

1. Added user to the group 'docker'
2. Confirmed changes after logging out and logging back in.
3. Able to use all docker commands without using sudo when using the terminal.
4. Issue persists only with VSCode not being able to detect the containers and images when VSCode is run as a non-root user.

Resolution: Device needs a full reboot for the changes to be reflected on VSCode. A logout is NOT sufficient.
