Custom airflow.cfg inside official Airflow docker-compose-CodePudding

I am running Airflow from this official docker-compose. I would like to hide default DAGs in the web app. Normally one can do this in airflow.cfg, how to hide default DAGs in docker-compose?

Cheers.

CodePudding user response：

You can set any option that exists in airflow.cfg by using environment variables following this syntax AIRFLOW__{SECTION}__{KEY}:

Sets options in the Airflow configuration. This takes priority over the value in the airflow.cfg file. Replace the {SECTION} placeholder with any section and the {KEY} placeholder with any key in that specified section.

Check the docker-compose.yaml file you got from Airflow and change the value of AIRFLOW__CORE__LOAD_EXAMPLES var to false, like this:

version: '3'
x-airflow-common:
  &airflow-common
