The top-level property `name` in the `docker-compose.yml` can be used to set the project name.
Alternatively, you can set the `COMPOSE_PROJECT_NAME` environment variable for the VS Code process, or specify it in a `.env` file in the same folder as the `docker-compose.yml`.
> **Note**: make sure to close all open VS Code windows first.
When no project name is configured and the `docker-compose.yml` is in the `.devcontainer` folder, the Docker Compose default of using the `docker-compose.yml` folder's basename is overridden with `${project-folder-basename}_devcontainer` to avoid name collisions with other projects.
