Run this command on your docker host to export the database from the docker container to your docker host:
docker exec -u postgres metasfreshdocker_db_1 pg_dump -Fc -d metasfresh > ./metasfresh_backup.pgdump
Note: You can check the actual docker name using
docker ps.
Use this parameter to exclude big tables that contain data you do not want to transfer:
-T <schema>.<tablename>
Example:
docker exec -u postgres mf_db_1 pg_dump -Fc -d metasfresh -T public.ad_issue > ./metasfresh_backup.pgdump
