docker image sizes
our images are really big:
- textgridrep-portal 245MB
- textgrid-indexutil 509MB
- textgrid-resolver 479MB
- aggregator 1.07GB
- rdf4j-service 365MB
- elasticsearch:7.9.3 742MB
opensearch gets even bigger
- opensearch:1 838MB
- opensearch:2 1.47GB
it would be good to optimize this a bit, e.g. with native builds for our services, using the same base images (so the docker layer needs to be pulled only once) and searching a minimal opensearch distribution
