Connect to Remote MSSQL db from Linux Docker container

Question

I have a linux docker container built on microsoft/mssql-server-linux/ image. The container doesn't have anything at this moment, I am trying to connect to remote MSSQL db hosted on windows server somewhere. I am not sure exactly how can I do that.

The documentation for microsoft/mssql-server-linux/ doesn't provide much of details. Any help would be appreciated.

Updated: I have got container working now. But, the container gets exited with code 0 if I try to create and seed db through bash script.

Here is docker file & docker-compose files

version: '2'
services:
  db:
    build: .
    ports:
      - "1433:1433"
    environment:
        ACCEPT_EULA: Y
        SA_PASSWORD: Password
        PATH: /opt/mssql-tools/bin:/opt/mssql/bin:$PATH
    container_name: db

FROM microsoft/mssql-server-linux:latest
EXPOSE 1433
RUN echo $PATH
RUN mkdir -p /usr/src/app
COPY ./db/* /usr/src/app/
WORKDIR /usr/src/app
RUN ls
RUN chmod +x /usr/src/app/dbInit.sh
RUN chmod +x /usr/src/app/dbSeed.sh
CMD /bin/bash ./entrypoint.sh

Here is my entrypoint.sh:

/opt/mssql/bin/sqlservr & /usr/src/app/dbInit.sh

dbInit.sh contains SQLscripts to create db, some tables and seed them. something like this.

sqlcmd -S localhost -U SA -P password -d master -Q "CREATE DATABASE dbo"

The docker-compose up --build successfully creates db, tables and seeds them. But the container is exited with code 0. Seems like SQL Server it self is closed.

The documentation is pretty clear..see the Connect and Query for more details

1.First you have to install SQLCMD tools,as they are not installed automatically

• Import the public repository GPG keys.

curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -

• Register the Microsoft Ubuntu repository

curl https://packages.microsoft.com/config/ubuntu/16.04/prod.list | sudo tee /etc/apt/sources.list.d/msprod.list

• Update the sources list and run the installation command with the unixODBC developer package.

sudo apt-get update sudo apt-get install mssql-tools unixodbc-dev

You can check out for further enhancements here :Install tools on Ubuntu

now you can query like below

for local :

sqlcmd -S localhost -U SA -P ''

For remote:

sqlcmd -S 192.555.5.555 -U SA -P ''
