Setup and runnning

All search filters are optional except startDate and endDate. See ceda-ard-finder-luigi.cfg.example for more filter examples.

Generate state file with search results:

LUIGI_CONFIG_PATH=ceda-ard-finder-luigi.cfg PYTHONPATH='.' luigi --module ceda_ard_finder SearchForProducts --startDate=2021-01-01 --endDate=2021-01-31 --local-scheduler

Output results as symlinks to CEDA locations:

LUIGI_CONFIG_PATH=ceda_ard_finder/ceda-ard-finder-luigi.cfg PYTHONPATH='.' luigi --module ceda_ard_finder CreateSymlinks --startDate=2021-01-01 --endDate=2021-01-31 --local-scheduler

Output results in a text file instead of symlinks. The date range queried is included in the filename:

LUIGI_CONFIG_PATH=ceda_ard_finder/ceda-ard-finder-luigi.cfg PYTHONPATH='.' luigi --module ceda_ard_finder CreateTextFileList --startDate=2021-01-01 --endDate=2021-01-31 --local-scheduler
