GeoServer s3-geotiff module with custom S3 provider fails

Question

I'd like to use the s3-geotiff module within GeoServer with a custom provider (Minio). The minio server is running properly and I could reach the tiffs in the bucket from a variety of s3 tools.

Following the instructions of the docs I've created a s3.properties file with endpoint, username and password strings.

I've placed the s3.properties file in the root of Geoserver_Data dir and also in the security folder. Unfortunately, using the s3 buckets tiff as a datastore fails. Geoserver always wants to reach the bucket on an AWS S3 instance. Using AWS, everything works as expected.

Any ideas?

Answer 1

To use a custom S3 provider, the s3.properties file path must be included via java system properties. So attaching -Ds3.properties.location=/opt/geoserver_data/s3.properties to my JAVA_OPTS within my docker build did the trick
