Downloading data does not work from the local website

[josvandervelde]

Reproduction

1. Run the docker compose.
2. Go to a dataset
3. Click on "download" (top right)

Actual

ns_error_unknown_host

Expected

Download a dataset file

Reason

The files stored on MinIO needs to be accessible from

1. other containers (for instance, to run the evaluation engine)
2. the user (from the website)

For the former, the minio url needs to be an url with which a pod on K8s can communicate with the MinIO pod. This is "http://minio:9000". For the second, the url should be http://localhost:9000. Because we store the url in the db, we have to choose one of them for now.

Possible solutions

1. Don't store the complete url in the db
2. ...

[PGijsbers]

nitpick: minio url is not hard-coded in the database, but instead in the PHP code, if I am not mistaken.

There are hard coded paths in the openml.file table as well as the configured path produced for the description responses.
