Answer 1

Have you tried with hos ip as your PostgreSQL host. I have just tested with asp.net core 3.1 and PostgreSQL both in windows 10 docker Linux separate container.

Its running without issue.

my connection string is

optionsBuilder.UseNpgsql("HOST=192.168.1.100;DataBase=TestIdentity;UserName=postgres;Password=*****;");

docker run --name=XXX -d -p 8081:8081 --add-host=computername:IP address name This was what finally make it work
