I am trying to install the a sample database in a docker container, using a Git Bash script file. This is on my Windows 10 development machine.
Yet when I try to execute a simple SQL query using 'git bash', I am getting the error

Error response from daemon: No such container: sqladventureworks /opt/mssql-tools/bin/sqlcmd

What am I doing wrong in my script file?

If I connect to the database using SSMS, the database behaves as expected.
