Airflow veterans please help,
I was looking for a cron replacement and came across apache airflow.
We have a setup where multiple users should be able to create their own DAGs and schedule their jobs.
Our users are a mix of people who may not know how to write the DAG python file. Also, they may not have access to the server where airflow is running.
Is it possible to create an airflow DAG via UI. I could not find any reference to the same. All examples speak about creating a python file and uploading it to the $AIRFLOW_HOME/dag/ directory. Users will not have access to this directory.
Rundeck for example allows user to add workflows and task dependencies via UI. Is there a plugin/functionality similar to this in airflow.
PS: I really like the way airflow shows the dependency graphs and want to try it out. But If creating a DAG is so complicated, then it will be a major problem for lots of my end users.

Because everything in Airflow is code, you can dynamically generate DAGs using Python alone. As long as a DAG object in globals() is created by Python code that lives in the dags_folder , Airflow will load it. In this guide, we'll cover a few of the many ways you can generate DAGs.
When your new DAG file is loaded in Airflow you can recognize it in the UI thanks to the version number. Because your DAG file name = DAG Id you could even improve the deployment script by adding some Airflow command line to automatically switch ON your new DAGs once they are deployed.
I don't think there is an out of the box solution. What I would try with your task is the combination: CWL(Common Workflow Language), Airflow, Rabix Composer
So, CWL is just a specification, you describe your workflow in YAML like syntax.
There is a package pip3 install cwl-airflow it can parse CWL into Airflow DAG https://github.com/Barski-lab/cwl-airflow.
Rabix Composer UI/graphical CWL editor.

elyra seems to be able to create airflow pipelines (did not try it):
