Attach VSCode to remote docker container using SSH (rootless-docker configuration) - docker

Question

I'm not able to make it working :( I have a setup where I connect using SSH to a remote server where I'm running several docker containers in a rootless-docker configuration.
I'm able to see the docker containers in VSCode and also to Attach shell to any of them.
However when trying to Attach Visual Studio Code I get the following error output:
[644094 ms] Start: Run in Host: docker version --format {{.Server.APIVersion}}
[644194 ms]
[644194 ms] Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
As you can see, it is trying to use unix:///var/run/docker.sock instead of unix:///var/run/user/1001/docker.sock which I configured in my workspace settings.json file:
{
"docker.environment": {
"DOCKER_HOST": "unix:///run/user/1001/docker.sock"
}
}
I have also enable rootless context under the Contexts menu.
Any idea why Attach shell is working while Attach Visual Code is not. I have read many of the solutions here and there, and tested them without success.
Edit:
I have also tried using the following settings.json but it doesn't work.
{
"docker.environment": {
"DOCKER_HOST": "ssh://jlanza#myserver.hostname.eu"
}
}
