modal.Mount

class Mount(modal.object.Object)

Create a mount for a local directory or file that can be attached to one or more Modal functions.

Usage

import modal
import os
app = modal.App()  # Note: "app" was called "stub" up until April 2024

@app.function(mounts=[modal.Mount.from_local_dir("~/foo", remote_path="/root/foo")])
def f():
    # `/root/foo` has the contents of `~/foo`.
    print(os.listdir("/root/foo/"))

Modal syncs the contents of the local directory every time the app runs, but uses the hash of the file’s contents to skip uploading files that have been uploaded before.

add_local_dir

def add_local_dir(
    self,
    local_path: Union[str, Path],
    *,
    # Where the directory is placed within in the mount
    remote_path: Union[str, PurePosixPath, None] = None,
    # Filter function for file selection; defaults to including all files
    condition: Optional[Callable[[str], bool]] = None,
    # add files from subdirectories as well
    recursive: bool = True,
) -> "_Mount":

Add a local directory to the Mount object.

from_local_dir

@staticmethod
def from_local_dir(
    local_path: Union[str, Path],
    *,
    # Where the directory is placed within in the mount
    remote_path: Union[str, PurePosixPath, None] = None,
    # Filter function for file selection - default all files
    condition: Optional[Callable[[str], bool]] = None,
    # add files from subdirectories as well
    recursive: bool = True,
) -> "_Mount":

Create a Mount from a local directory.

Usage

assets = modal.Mount.from_local_dir(
    "~/assets",
    condition=lambda pth: not ".venv" in pth,
    remote_path="/assets",
)

add_local_file

def add_local_file(
    self, local_path: Union[str, Path], remote_path: Union[str, PurePosixPath, None] = None
) -> "_Mount":

Add a local file to the Mount object.

from_local_file

@staticmethod
def from_local_file(local_path: Union[str, Path], remote_path: Union[str, PurePosixPath, None] = None) -> "_Mount":

Create a Mount mounting a single local file.

Usage

# Mount the DBT profile in user's home directory into container.
dbt_profiles = modal.Mount.from_local_file(
    local_path="~/profiles.yml",
    remote_path="/root/dbt_profile/profiles.yml",
)

from_local_python_packages

@staticmethod
def from_local_python_packages(
    *module_names: str,
    remote_dir: Union[str, PurePosixPath] = ROOT_DIR.as_posix(),
    condition: Optional[Callable[[str], bool]] = None,
) -> "_Mount":

Returns a modal.Mount that makes local modules listed in module_names available inside the container. This works by mounting the local path of each module’s package to a directory inside the container that’s on PYTHONPATH.

Usage

import modal
import my_local_module

app = modal.App()  # Note: "app" was called "stub" up until April 2024

@app.function(mounts=[
    modal.Mount.from_local_python_packages("my_local_module", "my_other_module"),
])
def f():
    my_local_module.do_stuff()
