Mounting a Host DirectoryĬreating a bind mount is pretty simple. This includes /Users, which covers most operations, but if you need to you can fix this in the Docker settings under Preferences > Resources > File Sharing by adding the target directory to the list. However, macOS has extra protections, and mounts outside of a few host directories may fail with “mounts denied” at runtime.

Note: since mounts are handled through the Docker API, they will work regardless of the host OS. While there are likely some pure in-Docker solutions to your problems, sometimes it’s simpler to just mount a volume. For example, you may have a log ingestion and aggregation service that would prefer if the container’s log files were in a directory accessible from the host. It’s also useful in production, if you have host services that depend on files in containers. Whatever your use case, mounting files isn’t a bad solution. Or you may want to mount an entire NGINX config directory to work on your website. For example, you may be working on a JS file or PHP plugin that you can just drag-and-drop into the container. However, in a dev environment, being able to directly mount a directory to enable hot-reloading of config or code can be very useful. This allows you to quickly scale and move images without worrying about the hardware they run on. If you wanted to, for example, update an app’s code or configuration files, you’d likely want to build a new version of the container and re-deploy. Generally, with Docker, you’d want images to run independently of the host system. These can be very useful both in development and production environments. Docker provides tools to bridge the filesystems of containers and the host operating system running the container, such as bind mounts and volumes.
