Create SQL Server database from a script in docker - sql-server

Question

Simple question I hope. I cannot find anything anywhere.
How do you create a database in a Microsoft SQL Server Docker container?
Dockerfile:
I am looking at the following Dockerfile:
FROM microsoft/mssql-server-windows-developer:latest
ENV sa_password ab873jouehxaAGR
WORKDIR /
COPY /db-scripts/create-db.sql .
# here be the existing run commnd in the image microsoft/mssql-server-windows-developer:latest
#CMD ["powershell", "-Command", "$ErrorActionPreference = 'Stop'; $ProgressPreference = 'SilentlyContinue';", ".\\start -sa_password $env:sa_password -ACCEPT_EULA $env:ACCEPT_EULA -attach_dbs \\\"$env:attach_dbs\\\" -Verbose" ]
RUN (sqlcmd -S localhost -U SA -P ab873jouehxaAGR -i create-db.sql)
docker-compose.yml:
I have put together the following docker compose file:
version: '3.4'
services:
sql.data:
image: ${DOCKER_REGISTRY}myfirst-mssql:latest
container_name: myfirst-mssql_container
build:
context: .
dockerfile: ./Dockerfile
environment:
SA_PASSWORD: ab873jouehxaAGR
ACCEPT_EULA: Y
Bringing it together
I am running the command docker-compose up against the above. And assuming create-db.sql file will simply create a database which is not relevant here to keep things minimal.
Errors
The error I get above is that the login for SA is invalid when it runs the .sql script:
Step 7/7 : RUN (sqlcmd -S localhost -U SA -P ab873jouehxaAGR -i create-db.sql)
---> Running in 2ac5644d0bd9
Sqlcmd: Error: Microsoft ODBC Driver 13 for SQL Server : Login failed for user 'SA'..
It looks like this runs before the password has been changed to ab873jouehxaAGR which typically looks like the command from mssql-server-windows-developer:latest.json from inspecting the image in vscode - \start -sa_password $env:sa_password -ACCEPT_EULA $env:ACCEPT_EULA -attach_dbs actually does.
Environment
I am running docker Docker version 18.06.1-ce, build e68fc7a on Windows 10.
Attach or script
I am not specifying attaching a database using the environment variable attach_dbs of which I see in many examples.
I am trying to find a best practice for managing a sql container from a point of view of end to end testing and a lot of articles seem to not cover the data aspect part - ie Development Workflow
I would be interested to hear in comments thoughts on these two approaches in the Docker world.

using following commands can solve your problem
docker-compose up --build -d
version: '3.4'
services:
sql.data:
image: ${DOCKER_REGISTRY}myfirst-mssql:latest
container_name: myfirst-mssql_container
environment:
SA_PASSWORD: ab873jouehxaAGR
ACCEPT_EULA: Y
and after that:
docker exec myfirst-mssql_container sqlcmd
-d master
-S localhost
-U "sa"
-P "ab873jouehxaAGR"
-Q 'select 1'
