使用 host.docker.internal 从 docker 连接到本地机器（主机）中的 SQL Server

Question

I'm trying to connect to my SQL Server instance running in my local computer using host.docker.internal (as recommended in https://docs.docker.com/docker-for-windows/networking/#use-cases-and-workarounds )

The host.docker.internal is successfully resolved to an IP, and it's ping-able

And I've opened up the port 1433 in my firewall configuration

Error message

Connection refused 192.168.65.2:1433

My connection string

Data Source=host.docker.internal,1433;Initial Catalog=;Persist Security Info=False;User ID=;Password=;MultipleActiveResultSets=True;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;

Answer 1

If anyone have similar problem, here's how I solve it

• Open SQL Server Configuration Manager
• Enable TCP/IP in Server Network Configuration
• Restart SQL Service Service

If it's still not working, there are a few more things to check

1. Firewall (open port 1433)
2. Enable remote connections to your sql server
