Data Persistency issue

[marbeno]

Hi,
I am running vcf-miner with Docker with a volume, i.e.
docker run -d -p 8888:8080 --name vcfminer --mount source=vcfMiner,target=/data/db/,type=volume vcfminer

If I load a vcf, stop the container and restart the same container vcf-miner is able to see the vcf previously loaded.
If the container is deleted and a new one is started the data are not available on vcf-miner. However, the data persist in mongodb as they can bee seen with mongo shell running inside the container.
