Connect to SQL Server in local machine (host) from docker using host.docker.internal

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
