Set Docker Compose project name

Visual Studio Code will respect the value you configure for the Docker Compose project name.

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.

To start VS Code from the command line:

# from bash
COMPOSE_PROJECT_NAME=foo code .

# from PowerShell
$env:COMPOSE_PROJECT_NAME=foo
code .

Alternatively, add the following entry to a .env file in the same folder as the docker-compose.yml:

COMPOSE_PROJECT_NAME=foo

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.
