Add another local file mount

Note: Mounting the local file system is not supported in GitHub Codespaces. Seedeveloping inside a container on a remote Docker host for information on mounting remote folders in this scenario.

You can add a volume bound to any local folder by using the following appropriate steps, based on what you reference indevcontainer.json:

• Dockerfile or image: Add the following to themounts property (VS Code 1.41+) in this same file:

  "mounts": [  "source=/local/source/path/goes/here,target=/target/path/in/container/goes/here,type=bind,consistency=cached"]

  You can also reference local environment variables or the local path of the workspace. For example, this will bind mount~ ($HOME) on macOS/Linux and the user's folder (%USERPROFILE%) on Windows and a sub-folder in the workspace to a different location:

  "mounts": [    "source=${localEnv:HOME}${localEnv:USERPROFILE},target=/host-home-folder,type=bind,consistency=cached",    "source=${localWorkspaceFolder}/app-data,target=/data,type=bind,consistency=cached"]

• Docker Compose: Update (orextend) yourdocker-compose.yml with the following for the appropriate service:

  version:'3'services:  your-service-name-here:    volumes:      -/local/source/path/goes/here:/target/path/in/container/goes/here:cached      -~:/host-home-folder:cached      -./data-subfolder:/data:cached     # ...

If you've already built the container and connected to it, runDev Containers: Rebuild Container from the Command Palette (F1) to pick up the change. Otherwise runDev Containers: Open Folder in Container... to connect to the container.
