I'm running the latest SQL Server docker container from DockerHub in a Linux environment. Port 1433 is forwarded from my container, and everything is working fine.

However, when I have tried to connect via SSMS to do remote debugging of a Stored Procedure, I see that the Debug->Start Debugging greyed out in SSMS. From what I understand, Debugging needs port 135 to be open/enabled in the container mapping as well.

So I changed my container startup script to be the following:

create --name mssql2 -e 'ACCEPT_EULA=Y' -e 'SA_PASSWORD=P@$$12345'  -p 135:135  -p 1433:1433  -v /home/eric/docker/mssql:/var/opt/mssql -v /usr/share/zoneinfo:/usr/share/zoneinfo:ro -e TZ=America/Toronto microsoft\

docker start mssql2

However, when I try to telnet to port 135, however, the connection is immediately closed:

eric@localhost ~/docker $ telnet localhost 135
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.

If I login into the mssql2 container and running netstat (after installing the net-tools package) I see:

root@2a378b0479d9:/etc# netstat -ano

So clearly MSSQL isn't even listening on port 135 within the container. What do I need to do to enable the remote debug port on the docker container? I do not even see any reference to port 135 in the logfile either. Is there a special switch I need to use in the MSSQL configuration to tell it to enable remote debugging?
