Docker Postgres data volume on the host

Question

I've a simple tiny issue. I have an app (ASPNET Core) and db (Postgres). I run the container of the db first and then run the app container so that the app can discover the db at runtime. Now I can connect the Postgres database using pgAdmin tool (On Windows) and everything works fine.

Now if I run the Postgres container with a data volume command like:

docker run -p 5432:5432 -d -v pg-data:/var/lib/postgresql/data --network=isolated_network --name postgres -e POSTGRES_PASSWORD=5432 postgres

Here, I can connect to Postgres instance running in the container and I get my data there. Here I have the question that where the data volume pg-data is available on the host?

Moreover, if I mount my Windows directories to the Docker Engine and run the command:

docker run -p 5432:5432 -d -v d:/data:/var/lib/postgresql/data --network=isolated_network --name postgres -e POSTGRES_PASSWORD=5432 postgres

I do see the data folder on in the D:\\ drive but I can't connect to this instance of the Postgres container with pgAdmin tool and my app stops working.

In linux default location of volume is:

/var/lib/docker/volumes

For windows i am not sure. but you can inspect container that will give you path and all details that you want.

docker inspect containername
