I am trying to get a simple windows postgreSQL container with external volume running…
The container itself runs perfectly on its own.
But when i want to shift the DATA directory to a docker volume, it always turns out empty.
According to https://docs.docker.com/storage/volumes/ - “Populate a volume using a container”,
it should migrate the content of C:\DATA to a new volume and mount it in the directorys place, but if i run:
docker run -it --entrypoint cmd --name pgtest --mount source=pgvol,target=C:/DATA pg
the directory C:\DATA is suddenly empty and postgres crashes…
I can’t find anything related in dockers logfile.
On researching this issue i only find this one: https://github.com/docker/for-win/issues/3499,
which is about mounting a host machine folder into a container…
Could someone confirm this behavior, or has an idea if i am doing something wrong?
