How to connect docker SQL Server linux with SQL Operations Studio (in windows)

As I mentioned, I have not managed to connect the container to SQL Operations Studio.

I am using docker compose to mount the containers, this is created correctly, but when I enter the credentials in SQL Server Operations Studio, it does not connect.

docker-compose.yml

version: '3'
services: 
  mssqllinux:
    image:  microsoft/mssql-server-linux:2017-latest

    env_file: 
      - ./docker.env
    ports:
      - "1433:1433"

docker.env

sa_password=RUc@ysd@f_P*yq4é
ACCEPT_EULA=Y
MSSQL_PID=Express

λ docker-compose ps

              Name                     Command           State           Ports
    -----------------------------------------------------------------------------------
    sqlserlinux_mssqllinux_1   /opt/mssql/bin/sqlservr   Up      0.0.0.0:1433->1433/tcp

Connection:

The error:

Several steps you can try.

First to remember, though you are inside of windows, but the database server is actually inside of Linux, and Linux is super case sensitive system. So, be sure your username is SA or sa.

Second thing is, in the server and port value, use a comma (,) instead of the colon (:), like below

Third, if the above steps didn't work for you, first make sure you can access the server using SQLCMD tool. You can follow this microsoft document for details. After you can successfully login to the database, you can reuse the server value and credentials in SQL Operations Studio Window.

Hope this helps.
