AgitatedDove14 trainsConfig is totally optional and you can put the config file itself in it.. e.g.:
trainsConfig: |- sdk { aws { s3 { key: "" secret: "" region: "" credentials: [ { host: "minio.minio:9000" key: "DEMOaccessKey" secret: "DEMOsecretKey" multipart: false secure: false region: "" } ] } boto3 { pool_connections: 512 max_multipart_concurrency: 16 } } development { default_output_uri: "s3://minio.minio:9000/trains/" } }
