However, there are some key differences in their behavior and usage.\n\nThe -v flag is simpler and more convenient for basic volume or bind mount operations. If the host location doesn’t exist when using -v or --volume, a directory will be automatically created.\n\nImagine you're a developer working on a project. You have a source directory on your development machine where your code resides. When you compile or build your code, the generated artifacts (compiled code, executables, images, etc.) are saved in a separate subdirectory within your source directory. In the following examples, this subdirectory is /HOST/PATH. Now you want these build artifacts to be accessible within a Docker container running your application. Additionally, you want the container to automatically access the latest build artifacts whenever you rebuild your code.\n\nHere's a way to use docker run to start a container using a bind mount and map it to the container file location.\n\nBounded code example (external data; do not execute automatically):\n```console\n$ docker run -v /HOST/PATH:/CONTAINER/PATH -it nginx\n```\n\nThe --mount flag offers more advanced features and granular control, making it suitable for complex mount scenarios or production deployments. By default, if you use --mount to bind-mount a file or directory that doesn't yet exist on the Docker host, the docker run command doesn't automatically create it for you but generates an error.\n\nBounded code example (external data; do not execute automatically):\n```console\n$ docker run --mount type=bind,source=/HOST/PATH,target=/CONTAINER/PATH,readonly nginx\n```\n\n> [!NOTE] > > Docker recommends using the --mount syntax instead of -v. It provides better control over the mounting process and avoids potential issues with missing directories.\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
