Answer 1

I had this problem today and I resolved it using a separate network (instead of using default "bridge" network).

1. docker network create test_network

2. docker container run -p 1433:1433 -d --name mssql -v mssql_data:/var/opt/mssql -e SA_PASSWORD=********** -e ACCEPT_EULA=Y --network=test_network microsoft/mssql-server-linux

3. docker container run -p 5000:80 --rm -e ASPNETCORE_ENVIRONMENT=Development --name aspnetcore --network=test_network aspnetcore-image

Also I have such connection string:

Server=mssql;Database=master;User=sa;Password=**********;

About previous answers regarding Connection String with IP address, it is not a good approach, because this address can be changed dynamically, it is better to use container names, as hostnames.
