Can I run dagster dev from a different directory than the workspace directory?

Yes, you can run

dagster dev

from a different directory than the workspace directory. The documentation provides several ways to tell Dagster how to find the Python code containing your assets and jobs, which allows you to run

dagster dev

from various locations. Here are the methods you can use: 1. From a file: You can specify the file containing your code directly using the

-f

argument when running

dagster dev

. For example:

dagster dev -f path/to/my_file.py

This command loads the definitions in

my_file.py

as a code location in the current Python environment. 2. From a module: You can load Python modules as code locations using the

-m

argument. For example:

dagster dev -m your_module_name

This loads the definitions defined at the top-level of the module, in a variable containing the

Definitions

object of its root

__init__.py

file. 3. Without command line arguments: If you have a

pyproject.toml

file with a

tool.dagster

section specifying the

module_name

, you can run

dagster dev

in the same directory as the

pyproject.toml

file without additional arguments. 4. Using a workspace file: By default, Dagster command-line tools look for workspace files (by default,

workspace.yaml

) in the current directory. To specify a different location for the

workspace.yaml

file, you can use the

-w

argument:

dagster dev -w path/to/workspace.yaml

Each of these methods allows you to run

dagster dev

from different directories by specifying the location of your code or workspace configuration.
