Why the docker run command is not recognizing the environment variable specified? - docker

Question

i am trying to download sentinel 2 data by running a docker container. I just want to download a single imagery for testing and so i am passing the filename as an environment variable but when i execute the docker run, it finds all relevant imageries and starts downloading all of them which is not what i want.
here is the command for executing the docker run statement
sudo docker run --rm -v $(pwd):/out_data \
> -e scihub_username=test \
> -e scihub_password=test \
> -e producttype=S2MSI2A \
> -e platformname=Sentinel-2 \
> -e files=S2A_MSIL2A_20190612T104031_N0212_R008_T31UGT_20190612T133140 \
> -e days_back=7 \
> -e footprint="POLYGON((5.8664000 50.3276000,9.4623000 50.3276000,9.4623000 52.5325000,5.8664000 52.5325000,5.8664000 50.3276000))" \

i have also defined the vairables in an ingestion.py file which is executing at docker build. it looks like this :
import os
import shutil
import logging
logging.basicConfig(level=logging.INFO, format='%(asctime)s - %(levelname)s - %(name)s - %(message)s')
logger = logging.getLogger("ingestion")
import requests
import datahub
scihub_username = os.environ["scihub_username"]
scihub_password = os.environ["scihub_password"]
result_url = "http://" + os.environ["BASE_URL"] + "/jobs/" + os.environ["JOB_ID"] + "/results"
logger.info("Searching the Copernicus Open Access Hub")
scenes = datahub.search(username=scihub_username,
password=scihub_password,
producttype=os.getenv("producttype"),
platformname=os.getenv("platformname"),
files=os.getenv("filename")
days_back=os.getenv("days_back", 2),
footprint=os.getenv("footprint"),
max_cloud_cover_percentage=os.getenv("max_cloud_cover_percentage"),
start_date = os.getenv("start_date"),
end_date = os.getenv("end_date"))
logger.info("Found {} relevant scenes".format(len(scenes)))
job_results = []
for scene in scenes:
# do not donwload a scene that has already been ingested
if os.path.exists(os.path.join("/out_data", scene["title"]+".SAFE")):
logger.info("The scene {} already exists in /out_data and will not be downloaded again.".format(scene["title"]))
filename = scene["title"]+".SAFE"
else:
logger.info("Starting the download of scene {}".format(scene["title"]))
filename = datahub.download(scene, "/tmp", scihub_username, scihub_password, unpack=True)
logger.info("The download was successful.")
shutil.move(filename, "/out_data")
result_message = {"description": "test",
"type": "Raster",
"format": "SAFE",
"filename": os.path.basename(filename)}
job_results.append(result_message)
res = requests.put(result_url, json=job_results, timeout=60)
res.raise_for_status()
that's how search looks like in datahub below:
def search(username, password, producttype=None, platformname=None, days_back=2, footprint=None, max_cloud_cover_percentage=None, start_date=None, end_date=None):
