![]() ![]() Since this setting only affects VS Code and related sub-processes, VS Code needs to be restarted (or the window reloaded) for it to take effect. On Linux, if you are referencing a Dockerfile, image, or Docker Compose in devcontainer.json, this will also automatically update the container user's UID/GID to match your local user to avoid the bind mount permissions problem that exists in this environment (unless you set "updateRemoteUserUID": false). If the image or Dockerfile you are using already provides an optional non-root user (like the node image) but still defaults to root, you can opt into having Visual Studio Code (server) and any sub-processes (terminals, tasks, debugging) use it by specifying the remoteUser property in devcontainer.json: "remoteUser" : "user-name-goes-here" The first user on a machine typically gets a UID of 1000, so most containers use this as the ID of the user to try to avoid this problem. The actual name of the user / group does not matter. Because of this, your container user will either need to have the same UID or be in a group with the same GID. This is because there is fundamentally no way to directly map Windows-style file permissions to Linux.ĭocker CE/EE on Linux: Inside the container, any mounted files/folders will have the exact same permissions as outside the container - including the owner user ID (UID) and group ID (GID). ![]() Locally, all filesystem operations will use the permissions of your local user instead. Locally, all filesystem operations will use the permissions of your local user instead.ĭocker Desktop for Windows: Inside the container, any mounted files/folders will appear as if they are owned by root but the user you specify will still be able to read/write them and all files will be executable. ![]() Specifically:ĭocker Desktop for Mac: Inside the container, any mounted files/folders will act as if they are owned by the container user you specify. If you do so, there are some quirks with local filesystem (bind) mounts that you should know about. Many Docker images use root as the default user, but there are cases where you may prefer to use a non-root user instead. ![]()
