Add another local file mount

Note: Mounting the local file system is not supported in GitHub Codespaces. See developing 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 in devcontainer.json:

• Dockerfile or image: Add the following to the mounts 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 (or extend) your docker-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, run Dev Containers: Rebuild Container from the Command Palette (kbstyle(F1)) to pick up the change. Otherwise run Dev Containers: Open Folder in Container... to connect to the container.
