Running your kedro pipeline from the command line could not be any easier to get started. This is a concept that you may or may not do often depending on your workflow, but its good to have under your belt. I personally do this half the time and run from ipython half the time. In production, I mostly use docker and that is all done with this cli.
π Unsure what kedro is? Check out this post.
Kedro run #
To run the whole darn project all we need to do is fire up a terminal, activate our environment, and tell kedro to run.
kedro run
Specific Pipelines #
Running a sub pipeline that we have created is as easy as telling kedro which one we want to run.
kedro run --pipeline dp
Single Nodes #
While developing a node or a small list of nodes in a larger pipeline its handy to be able to run them one at a time. Besides the use case of developing a single node I would not reccomend leaning very heavy on running single nodes, let the DAG do the work of figuring out which nodes to run for you.
kedro run --pipeline dp --node create_model_input_table_node
kedro run --pipeline dp -n create_model_input_table_node
Some DAG concepts #
We will cover more of the benefits that we get from the graph nature of the DAG in the future, but here is a quick peek at some things we can do.
kedro run --pipeline dp --to-outputs preprocessed_shuttles
kedro run --pipeline dp --from-inputs preprocessed_shuttles
kedro run --pipeline dp --to-nodes create_model_input_table_node
Multiple things #
You can stack up multiple kedro dag concepts into a single run command.
kedro run --pipeline dp --to-nodes create_model_input_table_node --to-nodes preprocess_shuttles_node
