I have the following setup:
- Windows (Host) – running docker desktop
- WSL2 – /home/user/workspace/nxg contains my project files
- Vscode connected with a Devcontainer
Project directory with relevant docker files:
.
├── .devcontainer
│ ├── devcontainer.json
│ ├── docker-compose.yaml
│ └── Dockerfile
├── docker-compose.build.yaml
├── docker-compose.yaml

]
}
},
"features": {

},
"postCreateCommand": {
"chown .pnpm-store" : "sudo chown node /workspace-nxg-/.pnpm-store",
"chown node_modules": "sudo chown node /workspace-nxg-/node_modules"
}
}
When I start DD (Docker desktop) and then VSC (visual studio code) to load my project I see 3/3 containers running:
- dev container
- postgres container
- nats container
This works great, I can query these container with docker ps -a and docker compose ls and both the containers are listed and the merged compose file by the devcontainer plugged is listed.
The problem and question:
The problem and question now is that I have another set of the exact same containers living somewhere in WSL. If I start VSC without DD it still works, these containers are not visible with docker ps -a and they’re always running the moment I start WSL.
In this situation where DD is not running here is the output of various commands:
On Windows:
C:UsersRohan>docker compose ls
NAME STATUS CONFIG FILES
C:UsersRohan>docker container ls
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
On WSL:

➜ ~ docker container ls -a

Please keep in mind that I have previously installed docker/k3s on WSL before I switched to DD so when cleaning WSL of the old docker I might have left some files. I feel like the devcontainers plugin has some kind of “backup” manner of managing containers but I don’t understand how to stop these containers and clean up their resources except for a killall and then also prevent this “backup” method.
I assume there’s a service file somewhere that’s starting these containers that I could delete but all of these are not the source of the problems in my opinion.
Hopefully I’ve provided enough info, there’s logs I could add with and without DD of the devcontainer plugin but those contain sensitive information so I’d prefer to scrub them and upload them only if needed.
