Xarray.combine by coords with Docker

[A-Spork]

When dockerised the wrappermethod(Collection_Sentinel_SST_Data) throws an error:

Errormessage.txt

The same command on a lokal windowsmachine goes threw without an error

[nuest]

Can you please provide the exact runtime environments on your Windows machine an in the container? All package versions, Python version, etc.

[A-Spork]

The runtime environment of my lokal machine is attatched.

runtime environment lokal machine.txt

The runtime environment for the server will be added shortly by a member of the server-dev team

The Docker Specification:
We specified all used packages for this microservice in the req.txt. If no version is specified the most recent is installed. Packages are installed with pip. We use python 3.8.6 as specified in the dockerfile. Docker is running on a windows machine with the wsl2 backend.

"The most recent version is installed" - the differences that might occur on different systems here might help you to track down the error, so that's why I asked for the exact versions.

[nuest]

I recommend you compare the two lists and see if anything sticks out.

If you'd like me to take an actual look, please prepare a minimal reproducible example. Thanks!

In the docker-compose branch from our GeoSoft2_Project Repository in the minExample Directory is a Example script which reproduces the error. The job.json file is also required. (https://github.com/GeoSoftII2020-21/GeoSoftII_Projekt/tree/Docker-compose) It needs the requests and docker package installed and also docker and docker compose. Also at least 12gb ram are needed. The whole log from the Server is printed in the Commandline (if exectuted in a commandline). It does not Terminate the the Server after its completion!

Did you see pydata/xarray#4213 ?

The problematic function is used a few times in the code: https://github.com/GeoSoftII2020-21/GeoSoftII_DataServer/search?q=xr.combine_by_coords

The problematic line in the code seems to be https://github.com/GeoSoftII2020-21/GeoSoftII_DataServer/blob/main/Wrapper/Collections_Sentinel2_SST_Data.py#L583

You should be able to force the error by writing a test that calls the function merge_datacubes(ds_merge) with the input data that you use.

Error solved by replacing the xArray.merge_by_coords with the xArray.open_mfdataset, which is based on the merge_by_coord function
